Why is the fire on the gas stove blue?

As a necessary tool for cooking at home - gas cooker, some users will have questions in their minds, why the flame produced by some cookers is blue, while some are yellow, what impact do these colors have on gas cooktops or cooking, which color flame is the standard flame, if you don't know, you must take a closer look at the following knowledge

1Why does the blue flame appear?

There are three types of daily practical gas sources in the user's home, namely: liquefied gas, artificial gas and natural gas. Generally speaking, the composition of artificial gas is carbon monoxide.

Methane, the main component of natural gas.

The main component of LPG is propane.

and butane. Regardless of whether the gas source is the same or not, the gas source fuel that can be fully burned will show a blue flame on the fire cover of the gas cooker, professionally speaking, the blue flame is the most ideal flame for the gas cooker, and this flame is more common in the product image painting of many kitchenware brands. ↓↓

2Why is there a yellow flame?

There are many situations that can lead to the formation of a yellow flame in a gas cooktop, so let's take a look at the reasons for the yellow flame of a gas cooktop:

1. The practical artificial gas in many areas is a typical example, because most artificial gas contains more impurities, resulting in insufficient gas combustion, so the formation of yellow flames.

2. It may also be that there is less air inside the gas cooker, so the gas source cannot be completely burned, resulting in the formation of a yellow flame, which is a product problem, most of which is inferior products, and some are product debugging problems, which will return to blue with a little adjustment.

3. Some users use liquefied gas tanks at home.

Sometimes there is less liquefied gas left in the liquefied gas tank, which may also lead to the formation of a yellow flame, in this case, the flame may be yellow because the air increases when burning, so that the flame is yellow, in this case, you can try to adjust the gas stove damper, so that the proportion of the gas source and the air can be coordinated to make it fully combusted, and this problem can also be solved, and the flame can be restored to blue.

4. The aperture of the nozzle of the gas cooker is too large, the size of the nozzle aperture is different according to the different sources of gas, when the aperture is too large, the flow rate of the gas often exceeds the rated flow, and the yellow fire is produced, when the oxygen is seriously insufficient, black smoke will also be produced.

5. Some gas sources are of poor quality and the gas source content is not fixed, which can also lead to the formation of yellow flames in the gas stove.

The flame on the gas stove is blue, because the main component of natural gas is methane, and the flame color of methane is light blue when it is burned. So the fire on the gas stove is blue.

The fire on the gas stove is blue, the reason is that the gas stove circulates through the air, and this circulation process has enough oxygen, so that the gas becomes an old man, the flame is more vigorous, and the temperature is higher

The fire on the gas stove is blue, which proves that his fire is particularly hard, well, still tasteless. The meals and dishes in the car are particularly fast. In general, the flame of gas or sticker gas will be slightly blue.

Why is the fire on the gas stove blue? Because the fire of the gas stove is blue, the gas has fully burned the blue flame indicates that the temperature is the highest, if it is not fully burned, do not be yellow.

Hello, the fire on the gas stove is blue, this is because the gas contains methane in it, and the flame of methane is blue.

What kind of fire on the gas stove is blue, this should be because of the reaction of carbon monoxide combustion, this should be combustion with oxygen, this should be blue, so it should be possible to learn, and after chemistry, it should be more difficult to understand.

Because the composition of coal gas is the chemical gas gas, which emits blue light when it encounters fire, which is a normal physical phenomenon.

If the temperature of a fire is higher, the more blue it appears, the temperature of blue is very high, followed by the yellow flame, and then the red flame, if the gas stove is a flame every time, one is that the combustion is very full, and the temperature is also the highest.

The more fully the gas burns in the household gas stove, the more blue the color of the flame and the higher the temperature of the flame, which is also the reason why the gas stove needs a blue flame.

The fire on the gas stove is blue, which is normal, and when the gas is burned, it is blue.

Fully burned natural gas will show a blue flame on the fire cover of the gas cooker, and the blue flame is the most ideal flame for the gas cooker. Yellow is impurities, and red is moisture, which causes insufficient combustion.

This means that he has fully mixed gas and air, so its flame is blue, if the flame is red, it means that he has been burning liquefied gas and has not been fully mixed with air.

There is no other flame if it has been fully burned. Its color is indeed pale blue. This means that your intake valve is well adjusted.

Because this is a gas shipment, it is blue, which is very normal.

The fire on the gas stove is blue, and I think that if the flame is blue, the quality of the gas is good.

A blue flame indicates that your gas is well adjusted, such a fire is high, and it is not easy to burn the pot.

If the fire on the gas stove is blue, if it is yellow, the gas is not good.

Why is the fire on the gas stove blue? The train on the gas stove, the blue one is the longest and most normal, but if it is. Yellow. That's not normal.

<> the reasons why the blue flame of the gas stove turns red: 1. The damper of the gas stove is not adjusted well, and the damper is too large or too small will affect the combustion state of the gas. 2. The gas stove outlet hole is blocked by food residues, and it is recommended to clean the gas stove outlet hole from time to time.

3. The oil stain and pot ash at the bottom of the pot are thick, and the blue fire will turn red if the gas combustion is not sufficient.

This answer is applicable to most brands of gas stove models such as Changhong, Fangtai, and Boss.

There are about three types of fuel that you can use for cooking at home: gas, natural gas, and liquefied petroleum gas. Generally speaking, the composition of gas is carbon monoxide, natural gas is methane, and liquefied petroleum gas is propane and butane.

The common yellow flame is caused by insufficient combustion, which can be improved by adjusting the damper. In the case of modified cooktops, poor design or high air pressure, it is still more common for the flame color of the cooktop to be abnormal. When using liquefied gas, it is found that the flame is red or jumping, which may be due to insufficient air, resulting in incomplete combustion, which is also easy to burn the bottom of the pot black.

The flame is green, which generally occurs when the core of the stove is copper-plated on the surface, and the copper is oxidized at high temperature to make the flame green.

<> the flame should be blue. The red flame may be due to: (1) the quality of the stove itself is not suitable for natural gas; (2) The effect of the transformed stove does not meet the requirements; (3) The residual impurities in the pipeline are formed with gas combustion; This air inlet volume is too large or too small will lead to insufficient combustion, it is necessary to adjust the appropriate air inlet volume according to the pressure value of the gas to ensure that the gas is completely and fully combusted.

If the damper is set too large or too small, it will lead to red fire. The surface of the pot stand is enamel, and due to the special material of the enamel, the flame will be found around the pot stand in red, which is the color of metal ions at high temperatures.

In addition, the fiery red flame will cause a layer of black ash to form at the bottom of the pot, which will affect the heat transfer and cause gas waste, and affect the appearance of the cookware. Therefore, if there is a red flame in the gas stove, it must be adjusted to blue. The damper passage is blocked.

There are carbon deposits, rust, spider webs and other dirt in the ejection tube, which will also affect the ejection ability and produce yellow fire, at this time, the carbon deposits, rust or cobwebs and other dirt in the ejector should be removed, and the yellow fire can be removed. Have you spilled rice residue on the gas stove recently, causing the stove hole to be blocked? If so, poke it with a toothpick or wire to clean the hole.

This is mainly due to the fact that the stove is blocked, and the gas cannot be sprayed and burned normally, which will also lead to red fire.

The flame turns red, it could be a problem with the pot holder on the gas stove! The surface of the pot holder will be coated with enamel, which contains metal ions, which will change color when heated at high temperatures, which is normal, so don't worry about anything. This is the case for many families.

Because sometimes the combustion is sufficient, the carbon dioxide is discharged, and sometimes the combustion is insufficient, and the carbon monoxide is produced in contact with the oxygen in the air, and this is the principle.

Because the flame on the gas stove is divided into internal and external flames. They were already set to look like this when they were made.

Normally, the flame on the gas stove should be blue. If there is a red flame, it is necessary to see if there is something wrong, such as the gas stove throttle adjustment is incorrect.

When the flame is large, it is visually red, and when the flame is small, it is blue.

Under normal conditions, the flame of the gas stove is light blue, the flame is clear, the height is about 20mm, occasionally accompanied by slight noise, and the fire power is relatively strong. The reason for the formation of the gas stove is that the gas source is not pure.

No matter how much air there is, it can also be extinguished. The air and gas are mixed too much, the proportion of formation is not right, and the formation is not sufficient. The air humidity and the material of the extinguisher will provoke the ** flame to be red.

The reason for the gas stove is that it is hot, or it may be that the damper of the gas stove is not well adjusted, and the damper is too large or too small will affect the extinguishing state of the gas. The treatment method is to adjust the damper conditioning plate of the gas stove, usually on both sides of the bottom of the gas stove, until the flame turns blue. The vents of the stove and fire lid of the gas stove can easily be blocked by food debris, and the fire outlet will be blocked.

To often clear the gas stove vent, you can use a toothpick to poke in the vent to clear out the dirty things inside, and the stove and fire cover of the gas stove should also be cleaned with baking soda or dish soap, and the gas stove will return to the blue flame.

There will be a valve under the gas stove, usually a knob, it is to regulate the air intake volume of the gas stove, because the extinguishing is inseparable from oxygen, the conditioning of the damper, to put it bluntly, is to control the size of the air volume, to ensure that the gas is abundant and extinguished, so the damper is too big, too small is not good, it will make the gas extinguish when the red fire is generated, we can properly adjust the damper, until the gas is extinguished for the blue fire. Sometimes, when we stir-fry and cook, oil or dirt gets on the fire hole, which will cause the fire hole to be blocked, and when the gas is extinguished, these foreign substances are mixed, which will cause the flame to be "impure" and turn into a red flame, and we can stop cleaning the fire hole.

If the gas is not pure, or lacking, it will cause the flame to turn red, we should check whether the gas is lacking at this time, and replenish it in time. It is also possible that the valve is too small, resulting in less gas intake, and we should twist the valve a little more.

This is very normal, and it is related to the situation of combustion, and if the combustion is not sufficient, the color change will occur.

It is normal for the gas to burn particularly well as a blue flame and for a small damper to be red.

This is not very reasonable, at this time it is likely that the fire hole of the gas stove is blocked, and sometimes there is no way to fully burn, and there will be some red fire.

Hello dear, what is the difference between a gas stove and a blue fire: the difference between a gas stove and a blue fire is that the definition is different. The blue fire of the gas stove means that the combustion of natural gas is the most sufficient at the moment, the heat generated is the largest, and the gas is the most efficient.

And the smoke and dust caused by this kind of combustion have the least harmful components and are the most environmentally friendly. The red fire of the gas stove is the main manifestation of insufficient gas combustion, and the actual effect of cooking rice is not good. The distinction between natural gas red and blue fire is different.

The blue fire of the gas stove means that the combustion of natural gas is the most sufficient at the moment, the heat generated is the largest, and the gas is the most efficient. And the smoke and dust caused by this kind of combustion have the least harmful components and are the most environmentally friendly. The red fire of the gas stove is the main manifestation of insufficient gas combustion, and the actual effect of cooking rice is not good.

The flame produced by gas that can be fully burned is blue. Hotel stoves are generally red flames, because the combustion rate is low, and a lot of gas or oil is not fully burned and lost.

After the gas stove is ignited, the flame is light blue, the fire power is vigorous, the height of the flame is uniform, and the utilization rate of gas is high. If you use an infrared gas stove to mix the gas with air well in advance and then burn it, the combustion will be intense and sufficient, and the bottom of the pot will not be blackened after long-term use.

It is not normal for a gas stove to be red. This is because the natural gas is not fully combusted. Normal flames are blue.

The main reasons for the appearance of red flames are as follows:

1. There are many impurities in the gas stove.

Some ingredients slip off the side of the pot during the usual cooking process and fall into the gas stove, accumulating more and more impurities, blocking the damper of the gas stove, causing the fire to be red. On the one hand, it is necessary to regularly clean the nozzles, air pipes, and fire cover holes for foreign objects, and the method is very simple: just poke the gas hole with a toothpick or wire.

On the other hand, it is also necessary to clean up the impurities at the bottom of the pot in time.

2. Adjust the damper.

If the damper is too small, use a tool to adjust the damper to the left, and observe the change of flame coloring, if the color of the flame does not change, continue to adjust the damper to the left; If a blue flame appears, stop adjusting the damper.

3. The gas is not pure.

Some households still use canned gas instead of natural gas, and some unscrupulous businesses add too many impurities to the gas in order to increase profits, and the burning flame will appear red. Insufficient combustion of gas can produce toxic substances, and people are even at risk of poisoning if they are in a confined environment. At this time, it is better to replace the gas tank or use natural gas.
