Why is the gas flame red?

Question 1: What causes the red flame of gas stoves? I only know that gas stoves will emit blue flames and red flames. I always feel that this is a matter of course, but scientific facts have proved that These two little flames have a lot of knowledge! Don't you believe it? Then take a look! One morning during the summer vacation, I was brushing my teeth and washing my face, and my mother was cooking breakfast: two sausage buns, two fried eggs and a bottle of custard. Inadvertently, I discovered that red flames flashed from time to time among the blue flames under the pot. Why is this? Afterwards, I asked my mother for advice, but she didn’t know why. So I asked my father, the "doctor" at home, for advice. After hearing my questions, my father smiled, led me to the stove, and began to answer my questions. "First of all, let's talk about the reason why the red flame appears." Dad said. "One reason is that the air vent of the gas stove is closed too tightly, and too little air enters the stove. By the way, the air vent cannot be opened too large, otherwise the red flame will still appear." As he said, Point to a place under the gas stove. This place is where the air outlet switch is controlled. "There is another reason, that is, there is too much dust at the fire outlet." At this time, I asked my father: "Dad, is there any harm in this fiery red flame?" Dad replied: "This flame will cause the pot to There is a layer of black stuff on the bottom, which will affect heat transfer, so we have to spend more gas and more fire to cook things, causing waste. In order to put an end to this phenomenon, son, I want to teach you. "Destroy this red flame." I felt a little dizzy after hearing this. "Turn on the gas stove." So, I pressed the ignition button of the gas stove and twisted it to the left. Suddenly, blue flames rose. Dad said: "This situation shows that it is just right." Then, he said: "Try turning the switch of the air vent to the left to the end." Unexpectedly, as soon as I did so, some red flames replaced part of the blue flames. , appears before our eyes. Dad said: "This situation means that it needs to be adjusted. Turn the switch back to the previous position." Sure enough, as soon as I did so, all the flames were blue again. Wow! I am truly worthy of being a "doctor" dad. He solved all the things I didn't understand at once. It's amazing! Ginger is still spicy!

Question 2: What causes red flames in natural gas? Use a stove that is compatible with natural gas and the flame should be blue. The appearance of a red flame may be due to the quality of the stove itself not being suitable for natural gas, or the effect of the modified stove not meeting the requirements. It may be due to residual impurities in the pipeline that are formed as the gas burns. It is also possible that the stove damper is not adjusted properly, resulting in incomplete combustion and red flames. The calorific value of natural gas fluctuates too high. If the calorific value exceeds the design range of the stove, incomplete combustion will also appear. Red flames can be made based on the above possibilities. analyze.

Ten little ways to save gas.

1. Be prepared. Before using gas, you must make preparations before using the fire to prevent the gas from burning in the air. When cooking, you should prepare the food before lighting the fire; if you are making soup or stewing, first bring it to a boil over high heat, then turn down the heat and just keep the pot boiling without overflowing. When using fire, try to reduce the number of times the stove is turned on and off to reduce gas leakage, air pollution and wear and tear on electronic ignition parts and stove switches.

2. Adjust the flame. Adjust the height of the flame of the stove burner. Under normal circumstances, the flame height is divided into three levels: medium, medium and low. Flames of different heights are used according to the different purposes of use. Generally, strong fire is required for cooking, and low fire can be used for decoction, and the flame should be combined with the flame height. corresponding to the bottom of the pot for optimal use.

3. Adjust the air volume. Adjust the air volume at any time to keep the stove flame blue. When burning natural gas, coal gas or liquefied gas stoves, yellow flames sometimes appear due to insufficient air intake. At this time, the air intake should be increased until the flame reaches a blue state.

4. Maintain the stove. Pay attention to the maintenance of the stove components so that the gas can burn fully. After the stove has been used for a long time, sometimes the flame becomes smaller, the flame becomes red, and the stove head turns black.

This is caused by oil dirt and carbon deposits falling into the small holes or nozzles of the burner. The oil dirt and carbon deposits should be removed in time to keep the flame in a normal burning state.

5. Cookers are energy-saving. Use energy-saving cookware and improve your cooking methods. Those who had the habit of steaming rice switched to braised rice, using pressure cookers for main and side dishes, and using thinner iron cookware instead of thick and bulky cast iron pots.

6. Dry the pots and pots. You should wipe away the water stains on the surface of pots and kettles before putting them on the fire. This will allow heat energy to be transferred into the pot as quickly as possible and save gas.

7. Protect yourself from the wind. If there is wind and the flames are swaying, you can use a thin iron sheet to make a "windshield" to ensure that the firepower is concentrated.

8. Check for air leaks. Always check the stove and the hose connected to it to avoid air leakage. The focus of the inspection is: whether the gas pipe joints are loose, whether the gas pipes are falling off, loose, cracked, etc. If there is any air leakage problem, try to solve it as soon as possible.

9. Pay attention to the temperature. Users who use liquefied gas should also pay attention to the ambient temperature where the liquefied gas cylinder is placed. The suitable temperature for liquefied gas cylinders is 10-20°C. Cylinders cannot be placed outside the kitchen in winter.

10. Choose the stove. The stove should be a brand-name product from a major manufacturer. Residential users must go to large stores or specialty stores to buy well-known brands. They should not buy off-brand stoves at street stalls for cheap. Most of these stoves cannot guarantee the quality and often have many faults, poor combustion, and black smoke. They are a waste of gas and harmful. Human health.

Question 3: Why does the gas stove have a red flame? The flame of the gas stove is red, which may be caused by the following reasons:

1. The air outlet of the gas stove is closed too tightly. , too little air entering the stove. Increase the size of the damper plate to increase the primary air intake and provide sufficient oxygen to support combustion.

2. The air outlet cannot be opened too large, otherwise the blue flame will turn red again. If the amount of air sucked in is too much at one time, the gas cannot be fully burned and some of it will escape.

3. There is dirt in the burner pipe. There is too much dust and oil residue at the fire outlet, and the gas supply is not smooth. It should be cleaned regularly to ensure smooth gas transportation.

4. The mixing tube and the gas combustion nozzle are not on the same axis, which interferes with the gas flow, or the fire cover is not properly covered, and red flames will appear. As long as you make slight adjustments and check that all parts of the burner are placed correctly, you can prevent and change the red fire into a blue fire.

5. The gas is impure, has impurities, or the gas pressure is too low. When the pressure of the gas pump in the community is insufficient, this situation is likely to occur during peak cooking hours. Avoiding peak cooking hours will improve the situation.

In addition, the fiery red flame will form a layer of black ash on the bottom of the pot, which will affect heat transfer, cause a waste of gas, and affect the appearance of the cookware. Therefore, if a red flame appears on a gas stove, it must be adjusted to blue.

Question 4: Why does a red flame appear on a gas stove? So I asked my father, the “doctor” at home, for advice. After listening to my question, my father smiled, then led me to the stove and started to answer the question. My question. "First of all, let's talk about the reason why the red flame appears."

So, I pressed the ignition button of the gas stove and twisted it to the left. Suddenly, blue flames rose. Dad said: “This situation is just right.

"Then, he added: "Try turning the switch of the air vent to the left to the end. "Unexpectedly, as soon as I followed the instructions, some red flames replaced part of the blue flames and appeared in front of us. Dad said: "This situation means that adjustments are needed. Turn the switch back to its previous position. "Sure enough, as soon as I followed the instructions, all the flames immediately turned blue again. Wow! As expected of a "doctor" dad, he solved all the things I didn't understand in one go. It's amazing! He is still hotter than ever!

Question 5: Why does the red flame appear on the gas stove? One morning, I was brushing my teeth while my mother was cooking breakfast. Inadvertently, I discovered that red flames flashed from time to time in the blue flame. Flame. Why is this? Afterwards, I asked my mother for advice, but she didn’t know why. So I asked my father, the “doctor” at home, and he smiled after hearing my question. At the stove, he began to answer my questions. "First, let's talk about the reason for the red flame. "Dad said. "One reason is that the air outlet of the gas stove is closed too tightly, and too little air enters the stove. By the way, the air outlet cannot be opened too large, otherwise red flames will still appear. "As he spoke, he pointed to a place under the gas stove. This place is where the size of the air outlet switch is controlled. "There is another reason, that is, there is too much dust at the fire outlet. "At this time, I asked my father again: "Dad, is there any harm in this kind of fire-colored flame? Dad replied: "The flame will form a layer of black stuff on the bottom of the pot, which will affect heat transfer. Then we will have to spend more gas and more fire to cook things, which will cause waste." In order to put an end to this phenomenon, son, I am going to teach you how to ‘destroy’ this red flame. "Turn on the gas stove." "So, I pressed the ignition button of the gas stove and twisted it to the left. Suddenly, the blue flame rose. Dad said: "This situation shows that it is just right. "Then, he added: "Try turning the switch of the air vent to the left to the end.

Turn the switch back to its previous position. "Sure enough, as soon as I followed the instructions, all the flames immediately turned blue again. I finally solved my question.

Question 6: Why does the gas flame turn red? Insufficient combustion!

p>

The reason is that after your pot is placed on the stove, it affects the air exchange between the outside world and the stove plate, so the oxygen between the bottom of the pot and the stove plate is reduced in a situation that is not conducive to ventilation.

In other words, the oxygen provided by the outside per unit time is not enough to make up for the oxygen consumed by combustion, but the flame will not go out.

If you remove the pot, it will resume immediately. Basket of Purple

Question 7: Why is the flame red when my gas is burning? I don’t know what material your pot is made of, but the electrons in the flame will turn red if potassium chloride is added. , when the flame generates energy, its electrons are adjusted to the top, and then jump down, producing light particles, and because the particles are red, red is produced

Question 8: The flame of a natural gas stove is red. What is the reason? What should I do? Lack of oxygen and insufficient combustion. Adjust the windshield under the stove to increase the air intake. Just check if the flame is blue.
