Gas fuel is a gaseous fuel at room temperature, which has very outstanding advantages compared with various solid fuels and liquid fuels: less pollution, high heat generation, easy operation, etc. It is an ideal quality boiler fuel. There are two kinds of gas fuels: natural gas fuels and artificial gas fuels.
Natural gas fuel
There are two kinds of natural gas fuel: gas field gas and oil field associated gas. Gas field gas is a kind of combustible gas from pure gas field, and oil field associated gas is a combustible gas produced in the process of oil extraction. Both of these natural gaseous fuels are mainly composed of methane, but also contain small amounts of alkanes, olefins, carbon dioxide, hydrogen sulfide and nitrogen, etc. Both have a high calorific value. Because natural gas is an important chemical raw material, only a few boilers near the production area can use natural gas as fuel.
Artificial gas fuels
There are various types of artificial gas fuels, including blast furnace gas, coke oven gas, generator coal gas and liquefied petroleum gas. Except for liquefied petroleum gas, all of them have low calorific value and are low calorific value gas. Although blast furnace gas and coke oven gas have lower calorific value, they are mainly used as chemical raw materials and fuel for various heating furnaces, and only a small amount is used as boiler fuel in situ. The occurrence of furnace gas and liquefied petroleum gas, generally not used as boiler fuel.
