At present, the fuels used in industry mainly include solid fuels, liquid fuels, and gas fuels. From the perspective of international development trends, the application of gas fuels is becoming increasingly widespread.
　　 Gas fuel is generally coal gas. If classified according to its production method, it can be divided into two categories: natural gas and artificial gas. In natural gas. There are gas wells, mine gas, petroleum mixed gas, and natural biogas extracted from underground through drilling. In artificial gas, there should be coke gas, generator gas, and liquefied petroleum gas.
　　 gas producerThe product also belongs to a thermal processing process of solid fuel (coal or coke) through gas, which uses oxygen or oxygen compounds (steam, carbon dioxide) to pass through a high-temperature solid fuel (coal, coke) layer, and the organic substances (air, steam) that act as oxidants are called gasifiers, generating a mixed gas containing hydrogen, carbon monoxide, methane, etc., called coal gas. According to the different gas agents, they are divided into the following three types:
1、 Air gas: using air as a gasifying agent.
2、 Water gas: using water vapor as a gasifying agent.
3、 Mixed gas: using air and water vapor as gasification agents. The composition of the three types of gas mentioned above is as follows: (expressed in volume percentage)
