What is the difference between Cohen appliance gas

  • Detail

Natural gas is a multi-component mixed gaseous fossil fuel, the main component of which is methane, with a small amount of ethane, propane and butane. After combustion, there is no waste residue and waste water. Compared with coal, liquefied gas and other energy sources, it has the advantages of safe and clean use. Many families used liquefied gas before, but if they want to cook with natural gas, they have to replace the stove with natural gas stove, and eliminate the original liquefied gas stove. Those who don't want to buy a new stove want to change the liquefied gas stove into natural gas stove. Is it safe to change the liquefied gas stove into natural gas stove

[transformation of gas stoves] method of changing liquefied gas stoves into natural gas stoves differences between liquefied gas stoves and natural gas stoves

if families previously used liquefied gas, it is urgent to change stoves to use natural gas. Because of the different combustion gases, there are some differences in special stoves. If liquefied gas stoves are directly used to burn natural gas, there are many potential safety hazards. If you don't want to change the stove, you can refit it

if the original gas stove uses liquefied gas, the aperture of its "gas outlet nozzle" (gas valve outlet) is generally 0.8mm, while that of natural gas should be 1.2mm. Therefore, if you have such practical ability, you can use a 1-1.1mm "straight shank fried dough twist drill" drill to ream the outlet hole (in order to consider the error in reaming, you don't directly use a 1.2mm drill)

method of changing liquefied gas stove to natural gas stove

1. First go to the hardware store to buy 1.2mm nozzle and corresponding tools for natural gas

2. Take down the 0.8mm nozzle on the liquefied gas furnace, use an electric drill and two drill needles of corresponding size to expand the hole, and change the hole diameter to 1.2mm

3. Install the nozzle in place, tighten it and test for leakage. Vent the gas in the original pipe, and then connect the pipe. Check whether the connection is tight to prevent gas leakage

4. Cover the gas stove panel, so that the gas stove can be changed

difference between liquefied gas stoves and natural gas stoves

1. First of all, we should understand the difference between natural gas and coal gas

natural gas is generally dry gas, mainly composed of methane, basically free of impurities, high calorific value, slow flame propagation speed and high transmission pressure. Coal gas is a mixture of various gases, containing impurities such as water, oil and dust, ammonia naphthalene, hydrogen sulfide, etc., and the transmission pressure is low. As an efficient, clean and high-quality fuel, natural gas has been widely used. The calorific value of natural gas is about 2.3 times that of artificial gas. Its main component is methane, with a content of more than 90%, and the rest is ethane, etc. Natural gas, like artificial gas, has the characteristics of flammability and explosion. Oxygen must be used to support the combustion when burning. At the same time, a large amount of carbon dioxide gas will be produced. If you stay in the closed space using gas for a long time, you will suffocate and die. When the gas content in the air exceeds 5%, a flash explosion accident will occur when encountering an open fire. Usually, the pressure of gas is high and the aperture of gas nozzle is small, while the pressure of natural gas is low and the aperture is large, so they cannot be mixed. In addition, when designing stoves, we usually care about the combustion supporting capacity of oxygen (20.9%) in the air, that is, the mixing ratio. LPG requires more air, and the other two are less

2. The working principle and shape of natural gas stoves and gas stoves are similar. The difference is that the eyelets of gas nozzles are different. We all know that the main reason is that the combustion calorific value of natural gas and gas is different, and their pressure is different. Everyone should choose according to their own needs. The pressure of natural gas is 2800 PA and that of pipeline gas is 2000 PA. Pipeline gas stoves can be changed into natural gas stoves. This process requires changing the nozzle and fire cover of the stove. Other things are solved by the gas company. The difference between natural gas stoves and gas stoves will not be dangerous as long as they are changed, but it is very dangerous to burn natural gas with the unchanged pipeline gas stoves

3. In terms of combustion characteristics, natural gas and gas are not interchangeable, so when gas is converted to natural gas, the original gas stoves, appliances, meters, transmission and distribution pipelines must be replaced or transformed. Among them, artificial gas appliances should be transformed or updated into natural gas appliances, and household stoves should be transformed into natural gas appliances by replacing nozzles and fire hole covers. The domestic water heater is converted into a natural gas water heater by changing the burner of the nozzle (main fire, long open fire, etc.)

is it safe to change the liquefied gas stove into a gas stove?

generally, it is not recommended to change the liquefied gas stove into a natural gas stove by yourself. It can be used after changing the nozzle, but there are also potential safety hazards, such as gas leakage caused by the rupture of the hose due to high pressure, carbon monoxide caused by insufficient gas combustion, etc. if it must be changed, it is best to ask the manufacturer of the stove to see whether it can be transformed, and invite professionals to refit it
