The reason why the pipe of the natural gas stove is larger than the gas stove

The differences between natural gas stoves and gas stoves are as follows:

1. Generally, the pressure of coal gas is large and the aperture of the gas nozzle is small, while the pressure of natural gas is small and the aperture is large, so it cannot be mixed. In addition, when designing the stove, it is usually also concerned about the oxygen (combustion capacity, i.e. mixing ratio, LPG requires more air, and the other two are less.

2. The working principle and shape of natural gas stove and gas stove are similar, the difference is that the orifice of the nozzle is different, the main reason is that the calorific value of natural gas and gas is different, and the pressure is different. The pressure of natural gas is 2800 Pa, and the pressure of pipeline gas is 2000 Pa. Piped gas stoves can be converted to natural gas stoves.

This process requires changing the nozzle and fire lid of the stove.

3. In terms of combustion characteristics, natural gas and coal gas are not interchangeable, so when gas is converted to natural gas, the original gas cooker, appliances, meters, and transmission and distribution pipeline network must be replaced or transformed. Among them, artificial gas stoves should be transformed or updated to natural gas stoves, and household stoves should be transformed into natural gas stoves by replacing nozzles and fire hole covers. Household water heaters are converted into natural gas water heaters by replacing nozzle (main fire, permanent open flame, etc.) burners.

Hello; Natural gas is a by-product of oil, which is pumped from the ground and is mainly composed of methane. Coal gas is a by-product of coking (coke, used in steelmaking), which is artificially smelted, and the main component is carbon monoxide. Their burning does not get in the way of each other.

It should be reminded that the pressure of natural gas is 2800 Pa and the pressure of pipeline gas is 2000 Pa.

Piped gas stoves can be converted to natural gas stoves. This process requires changing the nozzle and fire lid of the stove. The rest is taken care of by the gas company.

As long as it is changed, there is no danger, but it is very dangerous to burn natural gas with a piped gas stove that has not been changed.

The reason why the pipes of natural gas stoves are larger than those of coal gas. This is because the pressure of natural gas is high and the continuous combustion time is long.

Because the pressure of coal gas and natural gas is different, the required mixing ratio is different, so the nozzle aperture of gas is different, so they cannot be mixed. However, they can be used as long as the stove is replaced. At the same time, it will not happen even if it is mixed and used, but the thermal efficiency is not high.

The pressure of natural gas is 2800 Pa and the pressure of pipe gas is 2000 Pa, and they have different pressures. The combustion value is different.

Summary. At the same time, when we use the gas stove, we should open the windows for ventilation to prevent insufficient oxygen in the air and incomplete combustion of gas, resulting in inhalation of carbon monoxide poisoning. If you find a gas leak, stop using it immediately, turn off the main switch of the gas source immediately, and open the doors and windows for ventilation immediately.

If we finish cooking, don't turn off the hood right away, let it continue to run for 1 to 2 minutes, so that all the gas can be discharged. If the countertop is dirty, clean it directly, wipe the surface with a cloth and detergent.

Why does the gas stove use a lot of gas?

Hello dear, the reasons for the large gas consumption of the gas stove are: 1. The pipeline leakage will be caused, and the pipeline safety needs to be checked.

2. The gas pressure cooker is too large, the cross-sectional area of the flow changes, and the larger the differential pressure, the larger the gas flow. 3. The gas appliances used have been aged for too long. 4. The gas water heater is too high, resulting in a large amount of gas.

5. Affected by weather factors, the amount of use is generally large in winter and spring, and relatively less in summer.

At the same time, when we use the gas stove, we should open the windows for ventilation to prevent insufficient oxygen in the air and incomplete combustion of gas, resulting in inhalation of carbon monoxide poisoning. If you find a gas leak, stop using it immediately, turn off the main switch of the gas source immediately, and open the doors and windows for ventilation immediately. If we finish cooking, don't turn off the hood right away, let it continue to run for 1 to 2 minutes, so that all the gas can be discharged.

If the countertop is dirty, clean it directly, wipe the surface with a cloth and detergent.

At the same time, if you encounter a gas stove that is on fire but it will be extinguished after a while, because of the following reasons: 1. It is caused by the fire hole being blocked, and it needs to be dredged. 2. Because the thermocouple has been used for a long time and has been aged, the signal provided to the pulser is not strong, so the pulser will mistakenly think that there is no flame.

So when there is a small fire, it will be extinguished. It is recommended that replacement parts can be made. 3. Mainly due to the weakening of the signal due to internal aging, which affects the pulser, so there is a flameout.

Finally, I wish you a happy life and smooth work.

The two kinds of gas supply are different, the difference is that the pressure is different, the pressure of bottled liquefied petroleum gas (Lao Baixing pipe is called gas) is higher than that of pipeline natural gas (Lao Baixing is also referred to as pipeline gas), and there are two kinds in the manufacture of gas stoves, one is the use of bottled gas, and the other is the use of pipeline gas. The size of the nozzle is different, (small with bottles, large pipes) now you want to continue to make you have to find a professional to pay to renovate your gas stove, it is too old to buy a new one, but you have to explain that you use piped gas, you must pay attention to the use of piped gas must not use bottled gas stoves.

You are a typical technical blind problem.

When you say gas stove, is it gas? I think it can be called a gas stove, if the bottled gas used in front of it, it should be liquefied petroleum gas, so the stove should be a liquefied petroleum gas stove.

There are many kinds of pipeline gas, and now the main thing in various urban agglomerations is natural gas, but there are also some cities with artificial gas in the pipeline, and some cities are liquefied petroleum gas.

That is, what kind of stove is your stove, you don't know, what kind of gas your gas is, you don't know, how can the fire be normal? As a thematic researcher, I would like to remind you not to sacrifice your health in order to save a few small bucks. Traditionally, a stove can only use one type of gas code for the rest of its life from the date it leaves the factory.

The three types of gas I just talked about, each of which has many different codes.

No matter what career you are in, when the time is right, you should lower your head and care about the kitchen, it is related to our health.

The most fundamental problem is the mismatch of air supply. If you have time, go to my Weibo to take a look, there are not a few people who die in the kitchen now. I'm definitely not alarmist, paying attention to the kitchen is **** health.

Try mediating the downwinder.

The difference between a gas (liquefied petroleum gas) stove and a natural gas stove is that the gas output of the gas hole is inconsistent, the gas pressure is large, and the gas outlet of the stove is small. The liquefied gas pressure is small and the air outlet hole is large.

Similar to the difference between a car and a gasoline car, gas stoves are a general term, and natural gas stoves are one of the categories.

There are gasoline vehicles and diesel vehicles, and gas stoves are divided into artificial gas stoves, liquefied petroleum gas stoves and natural gas stoves. More than that, gasoline has a number; Natural gas is also divided into 12t and 10t, artificial gas has codes such as 7R, 6R, and 5R, and liquefied petroleum gas also has codes such as 19Y, 22Y, and 20Y. What kind of car burns what oil, in the same way, what stove also burns the corresponding gas.

Generally, when buying gas appliances, you will be asked whether to use pipeline gas or filled gas, if it is filled, they will give you another interface, if you already have a gas appliance, then go to the gas appliance market to buy an interface to replace it There is also a reminder to the downstairs owner, pipeline gas is better than filling gas, although the installation fee is more expensive, but the benefit is lifelong, our natural gas company has door-to-door pipeline inspection every year to ensure safety, and it will be automatically closed if it is not used for a long time. And the most important thing is that using natural gas is much cheaper than liquefied gas, a tank of liquefied gas (a family of three) cooking for a month and a half at most, the cost is seventy or eighty, but you add seventy or eighty yuan of natural gas can be used for at least two months, this is my experience with natural gas and liquefied gas, I hope it will help you.

If it's too big, change it.

The approximate amount of gas used per hour for a household gas stove is related to the actual situation.

1. The heat flow rate of each stove is different, and the nameplate under the stove will have a heat flow value. Depending on the heat flow, the amount of gas consumed per hour is also different.

2. The size of the stove is different, and the gas consumed per hour is also different.

3. The gas pressure is different, and the gas consumed per hour is different.

4. The gas consumption per hour is different when the household gas stove is turned on with double heads and when it is turned on with a single head.

5. The power of the gas stove is different, generally between, and the stove is marked.

6. When the household gas stove is turned on with the maximum single-head firepower, the hourly gas consumption = power * calorific value 10e6 power * calorific value cubic meters.

7. If you want to calculate accurately, you should measure the density and calorific value of liquefied gas before calculation, and the above method is the method to calculate. The easiest way to do this is to connect it to a flow meter and you can directly know how much gas is used per hour.

There are two rotatable iron sheets in the lower part of the gas stove, called the damper. They are the inner ring flame damper and the outer ring flame damper.

There are two possibilities for a large flame to be spewed out of the nozzle and at the same time air is brought in from the damper (Bernoulli's principle).

1. The amount of air entering the damper is too much, and the air flow velocity of each flame is large, resulting in stable flames;

2. If the gas pressure cooker is too large, the cross-sectional area of the flow will change, and the larger the differential pressure, the greater the flow velocity;

Treatment method: close the small damper, but the damper is not unlimited, so small that when the combustion oxygen is insufficient, the flame will turn red and the combustion efficiency will decrease;

Reduce the pressure of the gas pipeline, adjust the pressure reducing valve of the pipeline, and appropriately reduce the pressure of the pipeline. After adjusting the pipe pressure, readjust the damper until the flame turns pale blue.

Summary. Gas stoves generally use natural gas or liquefied petroleum gas, and these gases are delivered to the home gas stove through pipelines. There is a certain relationship between the pressure of the pipe and the pressure inside the gas stove, but the reason for the low pressure of the gas stove is not just the high pressure of the pipe

Gas stoves generally use natural gas or liquefied petroleum gas, and these gases are delivered to the home gas stove through open pipes. There is a certain relationship between the pressure of the pipe seepage belt and the pressure of the excitation part of the gas stove, but the reason for the low pressure of the gas stove is not only the high pressure of the pipe

In order to ensure the safety of household gas, the gas company has set up a pressure reducing valve on the vertical pipeline, please note: the pressure reduced by the pressure reducing valve is different from that of the gas stove.

The gas regulator is usually used inside the gas stove to adjust the pressure, and the high pressure of the natural gas or liquefied petroleum gas accompanied by the pipeline is adjusted to the low pressure suitable for the combustion of the gas stove, so as to ensure sufficient combustion and reduce potential safety hazards.

In addition, the design of the gas stove needs to consider the dispersion and dissipation of heat, and the components of the gas stove and the installation method of the stove also have a direct impact on the normal use and pressure of the gas stove

Summary. Dear, I am glad to answer for you: why is the pressure of the pipe high and the pressure of the gas stove small? ：

The pressure of a gas stove and a gas pipe are two different concepts. Normally, the gas supplier will deliver natural gas to the gas pipeline in the user's home and create a large enough pressure in the pipe to deliver the gas to the user's home. Gas stoves, on the other hand, need to depressurize the high-pressure natural gas transported in the pipeline to low-pressure natural gas suitable for combustion.

Therefore, when the gas pipeline enters the gas stove, a pressure reducer is usually installed to depressurize the high-pressure natural gas transported in the pipeline to low-pressure natural gas suitable for combustion. This is because too high a gas pressure not only consumes more natural gas, but can also lead to safety incidents.

What is the relationship between the pressure of the gas meter pipe and the pressure of the gas stove. Whoever is under more pressure and who is less stressed.

Why is the pipe pressure high and the gas stove pressure small?

Dear, I am glad to answer for you: why is the pressure of the pipe high and the pressure of the gas stove small? : The pressure of the gas stove and the gas banquet beam pipe are two different concepts.

Normally, the gas supplier will deliver natural gas to the gas pipeline in the user's home, and create a large enough pressure in the pipeline to deliver the gas to the user's home. Gas stoves, on the other hand, need to depressurize the high-pressure natural gas transported in the pipeline to low-pressure natural gas suitable for combustion. Therefore, when the gas pipeline enters the gas stove, a pressure reducer is usually installed to depressurize the high-pressure natural gas transported in the pipeline to low-pressure natural gas suitable for combustion.

Therefore, although the pressure of the gas pipeline is much greater than that of the gas stove, the gas pressure used by the gas stove is smaller due to the action of the pressure reducer. When using the gas stove, it is necessary to ensure the normal operation of the decompression shelter and work carefully and comply with the relevant rules and precautions to ensure the safe and stable operation of the gas stove.

Dear, you see, under normal circumstances, the pressure of the gas meter pipe and the pressure of the gas stove are two different concepts, and there is no necessary or direct correlation between them. The gas meter is a meter used to measure the flow rate and usage of natural gas in the macro and medium gas pipelines. There is always a pressure reducer in front of the gas meter, which reduces the pressure of high-pressure natural gas into low-pressure gas measured by the gas meter, and then transports it to gas stoves and other equipment through gas pipelines.

The gas stove uses low-pressure gas, which is usually reduced by a pressure reducer to meet the combustion needs of the gas stove. The gas pressure of a gas stove is much smaller than the gas meter pipe pressure, usually around MPA.

Therefore, there is no simple difference between the pressure of the gas meter pipe and the pressure of the gas stove, they are all set according to different usage needs.

Pro, the pressure of natural gas in the bend of the gas pipe in the liquid channel is much greater than the gas pressure obtained after passing through the gas stove pressure reducer. This is because the gas pipeline needs to transport a certain distance of natural gas to the user's home, and in order to ensure the stable flow of natural gas, the gas pipeline needs to maintain a certain level of pressure and burial force. The gas stove uses the gas in the gas pipeline after the pressure is reduced by the pressure reducer, and its pressure is relatively small, usually around MPA.
