Why gas burns with a red flame on the stove: factors affecting the color of the flame

How to clean nozzles

First, turn off the gas and check if the stove has cooled down. To clear the blockage, remove the cover and divider. As I said, there is a small hole inside. Take a sewing needle and clean it gently. It's not worth pushing and pushing him. It is enough to insert the tip and gently rotate the needle between your fingers.

At the same time, if there is dirt, it is useful to clean the divider itself and the cover. You can use a toothbrush, washing-up gel for dishes and a stream of warm water. It is impossible to pick with wire, carnation.Today's burners are not the ones used 50 years ago. They can't handle that kind of vandalism. Then wipe the whole thing dry, dry for half an hour or a little longer, collect and put in place. When assembling, make sure that the grooves and protrusions of the burner match. The cover must be in place evenly, without displacements and distortions.

Exploring fire in your own kitchen

Kitchen gas stoves work on two types of fuel:

1. The main natural gas is methane.
2. Propane-butane liquefied mixture from cylinders and gas holders.

The chemical composition of the fuel determines the temperature of the gas stove fire. Methane, burning, forms a fire with a power of 900 degrees at the top.

Combustion of a liquefied mixture gives heat up to 1950 °.

An attentive observer will note the uneven coloring of the tongues of the gas stove burner. Inside the fire torch, there is a division into three zones:

• A dark area located near the burner: there is no combustion due to lack of oxygen, and the temperature of the zone is 350 °.
• A bright area lying in the center of the torch: the burning gas is heated to 700 °, but the fuel does not burn completely due to a lack of oxidizer.
• Translucent upper section: reaches a temperature of 900°, and the combustion of the gas is complete.

The figures for the temperature zones of the fire torch are given for methane.

How to modify the jet

To get rid of the problem with smoky gas burners, you can adjust the jet by adjusting the size of the central hole. The larger the hole, the less pressure. Strict observance of alignment and verticality is required, otherwise the gas will poison to the side, which is fraught with accidents. This can only be done by a professional mechanic or a person who is well versed in technology. To work, you will need a set of needles, a soldering iron and solder.

General algorithm of work:

• shut off the gas supply;
• unscrew the top cover of the stove and find the jets (immediately under the burners);
• unscrew the jet with a spanner wrench;
• an oxide film is removed from the surface of the jet, which will improve the solder. The hole is carefully cleaned, the upper platform is cleaned with sandpaper;
• a small drop of solder is placed on the head of the bolt. She should close the hole and cover her edges;
• the excess is removed with a file or sandpaper. The area should be leveled so that a drop of solder slightly rises above it. Everything must be done very carefully, since you can remove the layer that holds the drop by the jet and the work will have to be redone;
• with the smallest needle, pierce the surface of the solder, making a new hole;
• using different needles, gradually expand the lumen;
• when the diameter reaches 0.5 mm, it is worth screwing into place, checking the operation of the plate. It is worth warning that the average value of jets for propane stoves is 1 mm, you may have to increase the size;
• if the gas burns steadily, with a blue flame, the job is done. By the way, while the burner has not warmed up, the appearance of individual rare yellow flames is permissible;
• if there are flashes, the flame is too small, the hole is enlarged by 0.1 mm, repeating the test.

However, I would advise you not to bother, especially since the presented method is not welcomed by either the fire or gas services. Necessary nozzles are sold everywhere. If you unscrew the sample, you can purchase the same one at a hardware store or a special store, but with a smaller hole. The price of this stuff is a penny. Problems with verticality and centering are excluded, which means that safety is ensured.

The gas in the column burns yellow: the fuel mixture is out of balance

The correct color for fire is blue.
She suddenly changed, turned yellow? This may be an indication that the burner is not getting enough air.

And this happens for several reasons:

• The suction holes can become clogged with dust particles that interfere with the normal air supply;
• The gas in the column lights up yellow if the type of equipment does not match the type of gas used.
  

In the first case, for the complete combustion of propane / methane, air is needed - in sufficient quantities. Mixed with gas fuel, it provides a high intensity of heating of the coolant.

If there is not enough air, and the “gas component” is much larger, the latter does not burn out in full, releasing carbon monoxide and turning the light yellow.

You will have to deal with if the flame soon turns red.This means that even more “blue fuel” enters the burner, its consumption goes astray, soot appears, and, for this reason, the column may spontaneously
. The equipment must be cleaned, and only a specialist can do this.

Yellow or orange fire

Most likely, the owners of any gas stoves periodically see the flame of such colors, but the problem quickly disappears on its own, so the owners do not worry. True, it also happens that the problem becomes permanent, and then the owners may become worried.

In fact, the problem is not so critical, and, most likely, you can even solve it yourself. Most often, it is observed on new stoves purchased no more than a year ago, but this is not an indicator of the poor quality of kitchen appliances - the phenomenon is observed both on cheap Chinese devices and on expensive samples of famous brands. The problem is that for any combustion process, abundant air is needed, and in this case, the holes for its suction are clogged, because there is not enough air.

In new stoves, this problem is due to the fact that, in order to prevent oxidation, their parts are covered with a thin film of oil during storage in a warehouse, on which fine dust sits perfectly. Since the air holes are quite small, this dirt can block a significant part of the gap and provoke the characteristic red tint of the flame. During the first year of operation, the problem is usually eliminated - the oil dries up, some of the litter burns out, and if a good owner also regularly cleans the stove, then problems generally quickly disappear.

By the way, the displacement of the damper located on the burner can also cause a change in the color of combustion. For some manufacturers, its shape is not well thought out, because its fall or partial displacement can partially block the access of air to the place of combustion.

Another reason for this phenomenon is that different gases can be used in systems. Natural gas and propane have different combustion temperatures, and they also need different amounts of air, so when buying a stove, a situation is possible when the equipment is designed for a different type of fuel. Here you can’t fix anything - due to incompatibility, the burners will always burn orange.

In most cases, small blockages are not such a terrible problem, but if the phenomenon becomes permanent, the danger may increase. Due to lack of air, a weak flame can simply go out. Most often, it goes out in the oven, where it is difficult for air to get in, and you won’t even notice it right away. At the same time, the included, but not burning, gas will begin to accumulate in the room, and in the worst case scenario, it can provoke an explosion that can smash the entire entrance.

Operating rules to prevent repeated violations

In general, the change in the color of the flame to orange-yellow, green, red happens due to insufficient cleaning and design errors.

Therefore, approach the purchase of equipment carefully.

• Before going to the store, find out what kind of gas is used in the house / apartment.
• After that, ask the sellers which models are designed for your type of gas.

These simple steps will minimize gas color change.

You can also eliminate the appearance of defects by replacing equipment with specialists (they can do the replacement themselves or observe you). Regular diagnostics of the condition by gas workers will extend the service life and prevent the occurrence of malfunctions. For independent control, you can take the regulator, it will reflect the state of the mixture of gas with air.

Compliance with instructions

Household appliances must be used according to the instructions, and the gas stove is no exception. By studying and following the manufacturer's recommendations, you make the operation safe and prolong the life of the equipment.

Proper maintenance of equipment

Below is the sequence of cleaning when the wrong shades appear on the gas.

1.	Do not use products containing chlorine
2.	Glass ceramics can be cleaned with soap and water and a sponge
3.	Do not use abrasive products if the surface is enamel or metal
4.	If you need to clean the holes from the burners - use a stiff brush, for the rest - a simple sponge

After cleaning, wipe the surfaces with a cloth until dry, and then just turn on the device.

For a thorough cleaning of the equipment, you can look at the structure in the instructions. In addition to the scheme, cleaning options are described there, which will allow you to organize everything qualitatively.

Wash household appliances completely daily so that accidental dirt does not get inside the structure. Because the dust, which is not immediately removed, begins to melt, char and cleaning is difficult. With continued operation, with each inclusion, the work worsens and you can finally break the equipment.

There is no need to be shy about contacting gas companies either. They will be able to eliminate systematic failures, give advice on operation and extension of service life.

Why do the colors of the flame change?

Many citizens may have noticed that in winter the amount of gas consumed increases significantly. Far from always this is facilitated by a decrease in the temperature outside and inside the room. Incorrect fuel consumption can be tracked even by the color of the flame. Today, there are several main reasons why it is changing.

Many citizens may have noticed that in winter the amount of gas consumed increases significantly

Incomplete gas combustion

Citizens should remember that the correct color for burning is blue. If it has changed to yellow or bright orange, then an impurity is involved in the supply. This may be due to both the ingress of industrial oil and the presence of carbon monoxide.
It is also worth noting that if air is not involved in the supply, the gas does not burn completely. Additionally, it can be distinguished that the air consists of several chemical components, without which the combustion reaction cannot occur.

Citizens should remember that the correct color for burning is blue.

With proper and stable combustion, 10 cubic meters of air should be removed per 1 cubic meter of domestic gas. In winter, its number is significantly reduced, this can be explained quite simply - citizens close their windows, hoping to prevent a draft.
Experts also say that it is very dangerous to allow the simultaneous operation of a gas stove and a hood over it. The absence of air can lead to the release of toxic decay, which negatively affects the well-being of households. The red flame of a home gas stove indicates the release of the decay of hazardous substances.

The red flame of a home gas stove indicates the release of the decay of hazardous substances.

Mechanical causes

Often the burners are simply clogged with dust or small particles of food. Even with timely visual cleaning, it is rare that housewives remove the protective panel and wipe it. Moreover, the fuel supply pipes themselves are almost impossible to reach.
It is also worth noting that when purchasing a new gas stove, it is worth preparing for the fact that in the first year the walls will clog constantly. This can be associated with a special oil film that settles during the manufacture of pipes.
In fact, dust delays the air supply, clean gas enters the burner itself, which can significantly increase consumption.

Often the burners are simply clogged with dust or small particles of food.

Important! The color of the flame itself also begins to change due to the admixture of decaying dust and the oil itself. Correct - blue or blue

What to do when the stove smokes

If the gas stove smokes, you first need to rinse it well:

• Remove the flame spreaders, if pieces of food and fat have stuck to their cells, they must first be soaked in a washing solution, then carefully cleaned of adhering dirt.
• If the nozzle hole is clogged, it can also be soaked, and then cleaned with a thin metal wire or needle. Then dry well.

If after washing the burners did not stop smoking, then you should pay attention to the diameter of the nozzle outlet. Modern models are equipped with two sets of nozzles (with a diameter of 6-7 mm - for liquefied, 8 mm - for central gas supply). If you decide to change the nozzles yourself, then you should remember that you need to twist them strictly perpendicular to the surface of the tile

Otherwise, the gas will be unevenly supplied to the burner. This can backfire

If you decide to change the nozzles yourself, then you should remember that you need to twist them strictly perpendicular to the surface of the tile. Otherwise, the gas will be unevenly supplied to the burner. This can lead to unpleasant consequences.

If the parts of the burner are deformed during operation, then they must be replaced with new ones, you should not even begin to correct them.

Carburizing view of the welding flame

If the ratio of oxygen to acetylene in the welding torch is less than 1, a carburizing welding flame is formed. The core of such a flame does not have a sharp contour, and the top of the core turns green, which indicates an excess amount of acetylene.

The recovery zone in such a flame is lighter than in a normal flame, and the torch has a yellow color. There is no clear boundary between the zones. Excess acetylene breaks down into carbon and hydrogen. Carbon easily passes into the weld pool, therefore, a carburizing flame is used if there is a need to carburize the weld metal or to replenish carbon if it burns out during welding. Such a flame is well suited for gas welding of cast iron.

Poor-quality cylinder gas

If the gas stove smokes, then the reasons are two possible problems.

• The first is based on an excess of sulfur content - it is she who, when burned, gives the same black smoke. In most cases, the cylinders are filled with propane, but a high sulfur content in them is also possible.
• The second reason is the unregulated gas pressure, which exceeds the nominal values ​​\u200b\u200bof the device.In most cases, the presented problems are encountered when using gas cylinders.

The cylinder is used to supply gas mainly in summer cottages

If consumers saw a smoking gas device, they need to take the following actions:

• To begin with, decide on further actions - use the gas in its current state, or try to relocate the cylinder or stove. In this case, one should be guided by the features of the soot content - so that less damage is done to the entire device.
• Next, they turn to an organization that is engaged in refueling gas cylinders. When applying, you can receive compensation, but you will have to prove your case - an increased sulfur content in the composition of the gas.
• If you cannot receive compensation, you should contact Rospotrebnadzor to restore justice.
• Already on the fact of the appeal, an analysis of the gas contained in the cylinder will be carried out. If it was initially decided to restore justice, it is recommended not to take additional independent actions in relation to the gas cylinder. During the examination, experts will not only confirm the increased sulfur content, but also determine the amount of remaining gas. This will help calculate the amount of compensation.

What to do when the gas stove does not burn well

As noted above, if the burners are intermittent, it is necessary to understand why this is happening and, based on this, make a decision to either flush or replace the burner.

Is it possible to fix the damage yourself

How can I flush the burner? The flush operation looks like this:

1. Remove the grate from the surface of the stove that covers the faulty burner.
2. Remove the divider (cover) from the surface of the burner and pull out the burner itself.
3. In order to get to the nozzle, it may be necessary to unscrew a few screws. However, it depends on the plate model.
4. Surely a certain amount of debris has accumulated under the burner, which must be removed.
5. Washing the burner and the parts included in its composition. To do this, you need to prepare a cleaning solution. It contains 10 parts of any dishwashing detergent and 1 part of water. It makes sense to keep the components of the burner in this composition for some time. The duration of soaking is determined by the degree of contamination. For thorough processing of the divider, it is advisable to use a toothbrush and toothpicks. After all parts are washed, they must be thoroughly dried.
6. The nozzle also needs to be washed, a toothpick can be used to clean the hole.
7. After all parts are dry, you can reassemble and install the nozzle and burner in place.

If electric ignition is installed on the stove, then it can also cause unstable burner operation.

If the spark is yellow or orange, then the entire unit will most likely need to be replaced. This device is beyond repair.

Calcium

Calcium is an element of the 4th period and the PA group of the Periodic System, serial number 20. The electronic formula of the atom is 4s2, oxidation states +2 and 0. Refers to alkaline earth metals. It has a low electronegativity (1.04), exhibits metallic (basic) properties. Forms (as a cation) numerous salts and binary compounds. Many calcium salts are sparingly soluble in water.In nature, it is the sixth chemically abundant element (the third among metals) and is found in a bound form. A vital element for all organisms. The lack of calcium in the soil is replenished by the application of lime fertilizers (CaCO3, CaO, calcium cyanamide CaCN2, etc.). Calcium, calcium cation and its compounds color the flame of a gas burner in a dark orange color (qualitative detection).

Calcium Ca

Silver-white metal, soft, ductile. In humid air, it tarnishes and becomes covered with a film of CaO and Ca(OH)2. Very reactive; ignites when heated in air, reacts with hydrogen, chlorine, sulfur and graphite:

Recovers other metals from their oxides (an industrially important method is calciumthermy):

Obtaining calcium in industry:

Calcium is used to remove non-metal impurities from metal alloys, as a component of light and antifriction alloys, to isolate rare metals from their oxides.

Calcium oxide CaO

basic oxide. The technical name is quicklime. White, highly hygroscopic. It has an ionic structure Ca2+ O2-. Refractory, thermally stable, volatile on ignition. Absorbs moisture and carbon dioxide from the air. Reacts vigorously with water (with a high exo effect), forms a strongly alkaline solution (hydroxide precipitation is possible), the process is called lime slaking. Reacts with acids, metal and non-metal oxides. It is used for the synthesis of other calcium compounds, in the production of Ca(OH)2, CaC2 and mineral fertilizers, as a flux in metallurgy, a catalyst in organic synthesis, a component of binders in construction.

Equations of the most important reactions:

Obtaining CaO in industry - roasting limestone (900-1200 ° C):

CaCO3 = CaO + CO2

Calcium hydroxide Ca(OH)2

basic hydroxide. The technical name is slaked lime. White, hygroscopic. It has an ionic structure Ca2+(OH-)2. Decomposes on moderate heat. Absorbs moisture and carbon dioxide from the air. Slightly soluble in cold water (an alkaline solution is formed), even less so in boiling water. A clear solution (lime water) quickly becomes cloudy due to the precipitation of hydroxide (the suspension is called milk of lime). A qualitative reaction to the Ca2+ ion is the passage of carbon dioxide through lime water with the appearance of a precipitate of CaCO3 and its transition into solution. Reacts with acids and acid oxides, enters into ion exchange reactions. It is used in the production of glass, bleaching lime, lime mineral fertilizers, for causticizing soda and softening fresh water, as well as for the preparation of lime mortars - pasty mixtures (sand + slaked lime + water), serving as a binder for stone and brickwork, finishing ( plastering) walls and other construction purposes. The hardening ("seizure") of such solutions is due to the absorption of carbon dioxide from the air.

Conclusions and useful

It is not always possible to figure out from the first time how to clean the gas burner from scale and dirt. The video below offers a detailed annotation on how to do this:

So, the usual color of a gas flame is blue.

If your burners burn differently, this is a reason to clean them or call a specialist for the most complete diagnosis. Do not delay with this question, because not just the color of the flame changes, but the composition of the combustion products.

The accumulation of carbon monoxide can lead to unnecessary consequences. Therefore, the issues of gas safety must be addressed first.

No, these are not the machinations of the dangerous GAZPROM. And not even the consequences of the unprofessionalism of the Klitschko administration. But the flame of gas on your stove can indeed warn of a possible threat. If it suddenly turned 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 unsafe amounts of carbon monoxide.

Combustion principles

For complete and safe combustion of gas, the stove must receive a sufficient amount of fuel mixed with oxygen in the required proportions. As a result of the combustion of the consistency given to us, carbon dioxide or CO2 is produced.

When the consistency of gas and oxygen is unbalanced, combustion does not occur one hundred percent, but carbon monoxide or CO becomes its 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, the flame is blue. When the consistency of gas and oxygen is unbalanced, bags of the lowest temperatures appear in the flame, since the fuel does not burn completely. The flame turns orange.

orange flame

An imbalance of fuel-oxygen consistency can occur in a number of circumstances.

Gas burner openings can become clogged with soot, resulting in uneven fuel delivery to the burner. When the flame burns off 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 proper amount of oxygen from mixing with the gas. With an insufficient supply of oxygen, only part of the gas is converted into a blue flame of the highest temperature, the rest goes into an orange flame of the lowest temperatures.

Carbon monoxide is a by-product of combustion. Gas stoves that produce blue flames typically release safe amounts of carbon dioxide into the air.An orange flame is a terrible sign that the concentration of carbon monoxide in the air is increased. Carbon monoxide poisoning has symptoms identical to flu 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 odor. Incorrectly installed and mismanaged gas stoves are responsible for hundreds of carbon monoxide poisoning deaths a year.

Green light

The solution of the problem begins with the recognition that the orange color of the gas is a terrible sign. The next step is to call in a qualified gas service professional for a detailed inspection of your stove and gas lines.

It may be useful for the master to clean the holes of the burners, adjust the position of the air damper, or replace the burner of the wrong size. It is impossible to adjust the balance of gas and oxygen in a combustible consistency yourself. A fundamental step towards home security is the installation of special monitors that track carbon monoxide in the air and warn if it exceeds the norm.
