Gas or gas is a general term for gaseous fuels
3, artificial gas (R)There are two main methods:One is the raw material of coal or coke into the industrial furnace in the combustion, and pass into the air and water vapor to generate combustible gas;Or isolated air heating, so that the occurrence of physical and chemical changes in coal, heating can be made after the purification of the gas can be obtained tar, ammonia, crude benzene and other chemical productsMain ingredients: H2; CO; CH4; C2; N2; CO2.Divided into three categories: 5R, 6R, 7R, rated pressure of 1000Pa.
2, natural gas (T)The main component is CH4, there are a small amount of unsaturated hydrocarbons and CO2, N2, O2 and so onDivided into five categories: 4T, 6T, 10T, 12T, 13T.10T, 12T, 13T rated pressure of 2000Pa, 4T, 6T rated pressure of 1000Pa;Vanward's products are mainly 12T, 13T. currently has basically not 13T production, the so-called natural gas is currently mainly refers to 12T products
Coal gas or gas is a general term for gas fuel, which can burn and release heat. There are many kinds of gas, which are mainly used for the residents and industrial enterprises, such as natural gas, artificial gas, liquefied petroleum gas1, liquefied petroleum gas (Y)It is a by-product of oil extraction and refining. The main components are C3H8 and C4H10.
