The gas burns orange, red or yellow. Ozone is a blue gas
Thank you Peppilotta#33
Give me back my faith in humanity#33
Well, I noticed a long time ago that less than half of the forum attended Russian lessons.
But that there were never so many people in chemistry # 33
Due to the presence of sodium salts (it is they that give the red color), the fire cannot become colder.
I, too, would not hurt to re-read the textbook, but, as far as I remember, household gas has no color or smell at all. The color during combustion is due to salts of one or another metal (for example, cadmium would give a red color). The smell of gas is also an impurity for a person to notice when leaking.
Gas burns orange or yellow
Imbalance in the air-fuel mixture occurs for various reasons. Air intake holes clogged with dust particles. obstructing the passage of air. In the first year of operation, gas equipment is especially prone to plaque. After stamping, the burner and the ignition group tube retain an oil film for some time. Adhering dust impedes the passage of air, but not gas. Increased gas supply to the burner upsets the balance when mixing the fuel supply to the main burner. When dust or soot falling from above gets into the gas, when burned in the chamber, they give yellow or orange flame.
Error. When buying gas equipment for a different type of gas, and not the one you use, it is also the reason for the appearance yellow color flame. For proper combustion of liquid propane and natural gas different amounts of air are required. Therefore, if you decide to buy a gas water heater. pay attention to what type of gas it is configured for.
As for the gas stove. The air control damper may be closed, dropped or come off the mounting. Preventing the intake of the required amount of air. In the absence of sufficient oxygen, only some types of stoves can ignite without problems from electric ignition and have blue flames. the rest lose heat and smoke, the stove should be repaired.
Gas burns red
Carbon monoxide It is a by-product of the combustion of any fuel. Geysers, which, when gas is burned, have Blue colour flames, emit a safe level of CO. orange flame or red indicates an increased presence of CO emission. The symptoms of carbon monoxide poisoning are similar to flu symptoms, headache, dizziness and nausea. Carbon monoxide is called the silent killer, fatally poisoning the unsuspecting user, while, odorless and colorless. So if the gas burns in red and the geyser goes out, professional cleaning should be taken care of. A few decades ago, due to the lack of a gas control system, gas water heaters killed up to a hundred people a year by poisoning them with carbon monoxide. We, as a company engaged in the repair and sale of gas equipment, recommend not to bring things to this point, but at the first manifestations of a malfunction of gas water heaters, call a professional craftsman.
What to do in this situation
Solving this problem starts with understanding what yellow. red or orange gas is a danger. If these symptoms are detected, the next step will be the scheduled arrival of a qualified craftsman for a technical inspection and repair of a geyser or other gas equipment. Get ready for the fact that you will need to clean the geyser, adjust the air lock in the boiler, replace the burner nozzles. Air-fuel mixture adjustment can be done independently. An important element of every home boiler room is the installation of sensors for the presence of carbon monoxide in room
Eliminating flame smoking is a simple and short process for craftsmen with extensive experience. The required tool can be found in any home kit. On average, our technicians spend about 30 minutes on a client, so choose and calculate a convenient time for a visit and leave a request for repairs. Workshop contacts to call the master
Memo to the people of Kiev - what does the orange flame of a gas stove mean
The editorial office of Russian Spring receives reports from residents of Kyiv that household gas is burning in an unusual color - orange.
What this means and what precautions should be taken in connection with this phenomenon, we tell in a specially prepared memo.
No, this is not the machinations of the insidious GAZPROM. And not even the consequences of the unprofessionalism of the Klitschko administration. However, the flame of gas on your stove can really warn of possible danger. If it suddenly turns orange instead of the usual blue, the burners may need to be cleaned or reinstalled. The orange color of the flame warns of improper combustion.. which in turn can lead to the release of dangerous amounts of carbon monoxide.
Combustion principles
For complete and safe combustion of gas, the stove must receive a sufficient amount of fuel, mixed in the right proportions with oxygen. The combustion of this mixture produces carbon dioxide or CO2. When the mixture of gas and oxygen is not balanced, combustion does not occur completely and carbon monoxide or CO becomes a by-product. The color of the flame is proportional to the heat intensity - the higher the temperature of the flame, the more correctly the proportion of gas and oxygen in the mixture is calculated, the more complete the combustion of the gas, and the flame is blue. When the mixture of gas and oxygen is not balanced, bags of lower temperatures develop in the flame, as the fuel does not burn completely. The flame turns orange.
orange flame
An imbalance in the fuel-oxygen mixture can occur for a number of reasons. The holes of gas burners can become clogged with soot and then the fuel is supplied to the burner unevenly. When the flame burns the soot, the visible temperature radiation turns orange. It may also be the wrong type of burner for the gas you are using, liquid propane and natural gas have different air-fuel ratio requirements. The air damper may not be properly sized or may be damaged preventing the correct amount of oxygen from mixing with the gas. With insufficient oxygen supply, only part of the gas turns into a blue flame. high temperature, the rest goes into the orange flame of lower temperatures.
Carbon monoxide is a by-product of combustion. Gas stoves that produce blue flames generally emit harmless amounts of carbon dioxide into the air. orange flame - danger sign the fact that the concentration of carbon monoxide in the air is increased. Carbon monoxide poisoning has flu-like symptoms: headache, dizziness, and nausea. In extreme cases, carbon monoxide lives up to its name as a silent killer, deceiving unsuspecting victims with its lack of color and smell. Incorrectly installed and out of time repaired gas stoves are the cause of hundreds of deaths from carbon monoxide poisoning a year.
Green light
Solving the problem starts with recognizing that the orange color of the gas is a danger sign.
The next step is to call a qualified gas service for a detailed inspection of your stove and gas communications. The technician may need to clean the burner holes, adjust the choke position, or replace an incorrectly sized burner. It will not work on your own to adjust the balance of gas and oxygen in the combustible mixture. Important step to home security - the installation of special monitors that monitor the content of carbon monoxide in the air and warn if its content exceeds the norm.

Let's say in the morning it burns with a blue flame by orange in the evening?
It is possible that the hydraulic fracturing equipment (gas control point) is junk (or cannot cope with the load), and in the evening, with an increase in gas consumption, it does not keep the required gas pressure at the outlet. That is, the gas pressure decreases with an increase in its consumption, which leads to poor performance of gas appliances, because they are designed for a nominal gas pressure, usually 130 mm of water. column (1274 Pa) if the pressure is less, then your case may occur (low gas pressure leads to insufficient air suction due to a decrease in the energy of the gas jet leaving the nozzle and heading to the stove burner).
Low-quality gas is allowed into the houses of Ukrainians, which does not heat
If the gas burns red or orange, then it is poorly purified.
Experts from the gas processing plant claim that the gas. which Ukrainians are now receiving, not too good quality due to its insufficient purification, Gazeta.ua reports.
If the gas burns red or orange, it means that it is poorly purified from hydrocarbons: propane, butane, hexane or butylene. Through these residues in the blue fuel poor heat transfer. As a result, the kettle boils longer. Because of this, the population burns more gas. It is impossible to mix the purified gas with any substances and compounds. It's not water or sand. And purified gas with untreated gas - theoretically, yes, it is possible, - says an employee of the Kachanovsky gas processing plant in the Sumy region.
The fact is that Russian gas is mixed with Ukrainian gas and the mixture is already served to Ukrainians. However, Ukrainian blue fuel is not of very good quality, which is why it gives negative effects, such as red flames and black oil on burners after prolonged use.
Earlier, the communist Oleksandr Golub expressed his suspicion that the gas that enters the apartments of Ukrainians is diluted with something: We still have to deal with the gas that our citizens receive today. The gas that goes to apartments and houses today is not the same as it was a few years ago. In the sense that to boil a kettle today it takes half an hour for it to stand on this gas.

Gas equipment is an unsafe device. Therefore, it is necessary to know the signs of various breakdowns in order to quickly eliminate them. The most common cause in gas equipment is a change in the color of the gas burning. Normally it should be blue. But if you notice that the color has turned red, orange or yellow, and an unpleasant smell has appeared and black soot is falling, then most likely the flame is smoking. In case of violation of injection, orange or yellow color appear on the flames. This indicates a lack of air.
In our article we will talk in detail about the burning of gas and the signs of poor performance of gas equipment.
Gas burns yellow or orange
An imbalance in the air-fuel mixture occurs due to various reasons. The air intake holes may be clogged with dust particles. Thus, an obstacle is created for the passage of air. Most of all, gas equipment is exposed to plaque in the first year of use. Since after stamping, the ignition group tube and the burner retain an oil film for some time. Therefore, the dust sticks and prevents the passage of air, but the gas passes perfectly. There is a large gas supply to the burner. And the balance is disturbed when the fuel supply to the burner is mixed.
Consequently, the gas enters with dust and soot, which is why the yellow and orange color of gas combustion occurs.
Another major mistake is the purchase of gas equipment for a different type of gas. After all, if you use one gas, and your equipment is designed for another, then the yellow color of gas combustion appears.
In order for propane and natural gas to burn correctly, different proportions of air are needed. Therefore, before buying gas equipment, you need to find out what type of gas it is intended for.
On a gas stove, the air control damper may fall, come off, or be closed. Thus, the required amount of air is not supplied. If there is not enough oxygen, then not all stoves can burn from electric ignition and have a blue flame. Many hoard and lose heat. In this case, it is necessary to repair the gas stove.
Gas burns red
Carbon monoxide is a by-product of the combustion of absolutely any type of fuel. Gas equipment releases a safe level of gas when the gas burns with a blue flame. If the flame turns red or orange, then this may indicate an increased release of carbon monoxide. If you have nausea, headache, dizziness, then these may be signs of carbon monoxide poisoning.
Carbon monoxide, as everyone knows, is colorless and odorless, so you need to control the color of the flame. If the geyser starts to go out and the gas burns red, then it is necessary to clean the equipment. For this, it is better to call a specialist.
In the past, when there was no gas control system, many people died as a result of carbon monoxide poisoning. Therefore, at the first suspicion of a carbon monoxide leak, it is urgent to call the appropriate specialists.
The correct color of gas burning is blue
In order for the gas to burn completely and be released maximum amount heat needs enough air. It mixes with the gas in the burner in the required proportions. Thus, a high intensity of heating and heat generation will be ensured. If there are any obstacles to the air intake, the gas does not burn completely and carbon monoxide is released. And the flame turns yellow.
The heating of the coolant and the color of the flame depend on the amount of incoming air. If the right amount of air is supplied, the color of the flame turns blue.
If the air-fuel mixture contains more gas than air, the flame may turn yellow. And after some time, it can even become red or white. This is due to the increased gas supply to the main burner. In this case, an incorrect fuel consumption occurs, and the burner begins to smoke. If the burner smokes, then it will not heat the water, the boiler will heat the coolant poorly, a black mark from the gas stove will be left on the dishes, and thus the food will be saturated with sulfur.
What to do in such a situation
After the color of the flame has turned orange, red or yellow, it should be understood that this indicates danger. Therefore, it is necessary to find the problem and fix it. After you have discovered a change in the color of the flame burning, you should contact a qualified specialist to diagnose and repair the gas device.
It may be necessary to clean the gas equipment, replace the burner nozzles and adjust the air lock in the boiler. You can adjust the air-fuel mixture yourself. This does not require the help of a wizard.
The main requirement before installing gas equipment is the installation of carbon monoxide detection sensors.
For qualified specialists, it will not be difficult to eliminate flame smoking. This does not require special tools. At the slightest suspicion of a carbon monoxide leak, contact a specialist immediately.
A change in the color of the flame of a gas stove burner may indicate the presence of carbon monoxide.
The flame of a gas stove or water column should be blue. The presence of flashes of orange, red or scarlet color in the fire indicates incomplete combustion and the formation of carbon monoxide, the poisoning of which is fatal.
“The main condition for burning gas in everyday life is the flow of air. In the process of gas combustion, a chemical reaction occurs between the combination of oxygen contained in the air with carbon and hydrogen in the fuel. The reaction occurs with the release of heat, light, as well as carbon dioxide and water vapor. It takes about 10 cubic meters of air to burn 1 cubic meter of natural gas. With incomplete combustion of gas, a long, smoky, luminous, opaque, yellow torch is observed. A change in the color of the combustion of natural gas to yellow, orange, reddish may indicate incomplete combustion of gas for a number of reasons. Like: lack of air intake, excess air, clogging of the gas burner (dust, soot, etc.). The whole range of reasons in each specific case can be assessed by a specialist only during an on-site inspection, ”Alexey Mizharev, head of the department for the technical operation of gas equipment at SVGK LLC, told AiF-Samara.
The blue color of the flame in the gas column is an indicator of the release of a safe level of carbon monoxide (CO) during combustion. Orange or red flame is an indicator of increased CO emission. Carbon monoxide is colorless, odorless, the symptoms of carbon monoxide poisoning in mild cases are similar to the symptoms of the onset of the flu. Therefore, gas equipment should be treated carefully.
If the color of the flame in the gas burners of the stove or column (boiler) changes to yellow, red or orange, you must contact the gas service at the place of residence and call a specialist to determine the causes and eliminate them. In an emergency, you should contact the 24-hour emergency service at 04 (or 104 for cellular subscribers) for help. And be sure to ensure before their arrival a good flow of air into the room where the gas appliance works.
Gas safety rules
Work on the installation or transfer of gas equipment should be entrusted only to a specialized gas company.
It is unacceptable to install gas water heaters (columns) without proper removal of fuel combustion products. Experience shows that with poor ventilation of the premises, cases of carbon monoxide poisoning are not uncommon.
Install a carbon monoxide alarm.
Monitor the normal operation of gas-consuming appliances. Check the draft before turning them on and during operation. At the slightest suspicion of poor draft in the chimney, you must immediately stop using the gas and contact a specialist to check the chimney and restore normal ventilation.
It is unacceptable to turn off the safety and regulation automation, use a heating boiler with faulty automation. It is necessary to invite a representative of a specialized service organization to repair.
It is forbidden to use gas appliances with closed windows, gratings of ventilation ducts, absence of draft in the chimney and ventilation duct, slots under the doors of the bathroom where the gas water heater is installed.
Simultaneous operation of a gas column and an exhaust hood over a gas stove with a closed window is dangerous, even with a working chimney and ventilation duct! In this case, as a rule, there is a violation of the removal of combustion products. As a result, odorless carbon monoxide enters the dwelling and leads to severe poisoning of people.
With the onset of sub-zero temperatures, freezing of chimneys is dangerous, which can lead to a violation of the ventilation of residential premises. Owners of houses (both private and departmental, as well as municipal) are required to check chimneys for proper draft.
It is unacceptable to leave gas appliances unattended, except for those designed for continuous operation and having appropriate automation.
It is dangerous to use gas and gas appliances for other purposes, in particular for space heating.
If you smell gas in a residential area, you must: immediately stop using gas appliances, turn off the taps to and on gas-consuming appliances, open windows or vents for ventilation, call the gas supply emergency service from a non-gassed room by calling 04 or 104 for cellular communication.
As a measure to prevent carbon monoxide poisoning, it is possible to install a gas pollution control sensor in the apartment with a gas valve that stops the gas supply when a danger to human life is detected.
Household gas equipment is considered a high-risk device, so it is important to know some of the symptoms of breakdowns for a prompt response. If you find that a yellow color prevails in a gas appliance during the combustion of gas, black soot falls, an unpleasant smell of burning is felt, most likely the flame is smoking. Yellow or orange color on the flames indicates a lack of air mixture (injection failure). In this article we will talk in detail about the combustion of gas and analyze external signs poor performance of the gas burner.
Proper combustion of gas - blue color
In order for the gas to burn completely, with maximum heat release and high heating intensity, it must receive the necessary amount of air, which is mixed with the gas in the main burner in the correct proportions. But when the amount of incoming air is limited by something, the combustion of gas is incomplete, a large amount of carbon monoxide (CO is a by-product) is released and the flame turns yellow.
The color of the flame and the heat load (heating of the coolant) directly depends on the amount of oxygen supplied. The intake of air within the normal range paints the flame blue. If the air-fuel mixture is unbalanced (gas predominates), the flame will turn yellow and eventually turn red and white. This is caused by increased gas supply to the main burner.As a result, the fuel is consumed incorrectly - the burner smokes. At the same time, the column does not heat the water, the boiler heats up the coolant poorly, the gas stove leaves a black mark on the dishes, “saturating” the food with sulfur.
Gas burns orange or yellow
Imbalance in the air-fuel mixture occurs for various reasons. The air intake holes become clogged with dust particles, preventing air from passing through. In the first year of operation, gas equipment is especially prone to plaque. After stamping, the burner and the ignition group tube retain an oil film for some time. Adhering dust impedes the passage of air, but not gas. Increased gas supply to the burner upsets the balance when mixing the fuel supply to the main burner. When dust or soot falling from above gets into the gas, when burned in the chamber, they give a yellow or orange color to the flame.
Common mistake. When buying gas equipment for a different type of gas, and not the one you use, it is also the cause of the yellow color of the flame. Propane and natural gas require different proportions of air to burn properly. Therefore, if you decide to buy a gas water heater, pay attention to what type of gas it is configured for.
As for the gas stove. The air control damper may be closed, dropped, or come off the mount. Preventing the intake of the required amount of air. In the absence of sufficient oxygen, only some types of stoves can ignite without problems from electric ignition and have blue flames, the rest lose heat and smoke, the stove should be repaired.

Ozone is a gas. Unlike many others, it is not transparent, but has a characteristic color and even a smell. It is present in our atmosphere and is one of its most important components. What is the density of ozone, its mass and other properties? What is its role in the life of the planet?
blue gas
In chemistry, ozone does not have a separate place in the periodic table. This is because it is not an element. Ozone is allotropic modification or a variation of oxygen. As in O2, its molecule consists only of oxygen atoms, but has not two, but three. Therefore it chemical formula looks like O3.
Ozone is a gas blue color. It has a distinct pungent odor reminiscent of chlorine if the concentration is too high. Do you remember the smell of freshness in the rain? This is ozone. Thanks to this property, it got its name, because from the ancient Greek language “ozone” is “smell”.
The gas molecule is polar, the atoms in it are connected at an angle of 116.78°. Ozone is formed when a free oxygen atom is attached to an O2 molecule. This happens during various reactions, for example, the oxidation of phosphorus, an electric discharge, or the decomposition of peroxides, during which oxygen atoms are released.
Ozone properties
Under normal conditions, ozone exists in molecular weight almost 48 g/mol. It is diamagnetic, that is, it is not able to be attracted to a magnet, just like silver, gold or nitrogen. The density of ozone is 2.1445 g/dm³.
In the solid state, ozone acquires a bluish-black color, in the liquid state, an indigo color close to violet. The boiling point is 111.8 degrees Celsius. At a temperature of zero degrees, it dissolves in water (only in pure water) ten times better than oxygen. It mixes well with nitrogen, fluorine, argon, and under certain conditions with oxygen.
Under the action of a number of catalysts, it is easily oxidized, while releasing free oxygen atoms. Connecting with it, it immediately ignites. The substance is able to oxidize almost all metals. Only platinum and gold are not amenable to its action. It destroys various organic and aromatic compounds. Upon contact with ammonia, it forms ammonium nitrite, destroys double carbon bonds.
Being present in the atmosphere in high concentrations, ozone spontaneously decomposes. In this case, heat is released and an O2 molecule is formed. The higher its concentration, the stronger the heat release reaction. When the ozone content is more than 10%, it is accompanied by an explosion. By increasing temperature and decreasing pressure, or by contact with organic matter decomposition of O3 is faster.
Discovery history
In chemistry, ozone was not known until the 18th century. It was discovered in 1785 thanks to the smell that the physicist Van Marum heard next to a working electrostatic machine. Another 50 years later did not appear in any way in scientific experiments and research.
The scientist Christian Schönbein studied the oxidation of white phosphorus in 1840. During the experiments, he managed to isolate an unknown substance, which he called "ozone". The chemist came to grips with the study of its properties and described methods for obtaining the newly discovered gas.
Soon, other scientists joined the research of the substance. The famous physicist Nikola Tesla even built the first in history. The industrial use of O3 began at the end of the 19th century with the advent of the first installations for supplying drinking water to homes. The substance was used for disinfection.
Ozone in the atmosphere
Our Earth is surrounded by an invisible shell of air - the atmosphere. Without it, life on the planet would be impossible. Components atmospheric air: oxygen, ozone, nitrogen, hydrogen, methane and other gases.
Ozone does not exist on its own and only occurs as a result of chemical reactions. Close to the surface of the Earth, it is formed due to electrical discharges of lightning during a thunderstorm. In an unnatural way, it appears due to exhaust emissions from cars, factories, gasoline fumes, and the action of thermal power plants.
Ozone in the lower layers of the atmosphere is called surface or tropospheric. There is also a stratospheric one. It occurs under the influence of ultraviolet radiation coming from the sun. It is formed at a distance of 19-20 kilometers above the surface of the planet and stretches to a height of 25-30 kilometers.
Stratospheric O3 forms ozone layer planet, which protects it from powerful solar radiation. It absorbs approximately 98% of ultraviolet radiation with a wavelength sufficient to cause cancer and burns.
Substance use
Ozone is an excellent oxidizer and destroyer. This property has long been used to purify drinking water. The substance has a detrimental effect on bacteria and viruses that are dangerous to humans, and when oxidized, it itself turns into harmless oxygen.
It can kill even chlorine-resistant organisms. In addition, it is used to cleanse Wastewater from destructive to environment petroleum products, sulfides, phenols, etc. Such practices are common mainly in the United States and some European countries.
Ozone is used in medicine for the disinfection of instruments, in industry it is used to bleach paper, purify oils, and obtain various substances. The use of O3 to purify air, water and premises is called ozonation.
Ozone and man
Despite all their beneficial features, ozone can be dangerous to humans. If there is more gas in the air than a person can tolerate, poisoning cannot be avoided. In Russia, its permissible rate is 0.1 μg / l.
If this norm is exceeded, typical signs of chemical poisoning appear, such as headache, irritation of the mucous membranes, dizziness. Ozone reduces the body's resistance to infections transmitted through the respiratory tract, and also reduces blood pressure. At gas concentrations above 8-9 μg / l, pulmonary edema and even death are possible.
At the same time, it is quite easy to recognize ozone in the air. The smell of "freshness", chlorine or "crayfish" (as Mendeleev claimed) is clearly audible even with a low content of the substance.
