　　Gas generator sets use coal mine gas, biogas, and other fuels, and their gas composition is complex, containing impurities such as dust, hydrogen sulfide, moisture, and heavy hydrocarbons. Untreated gas may cause engine corrosion, carbon deposition, increased wear, and even lead to safety accidents such as explosions. Therefore, building an efficient gas purification system is the core link to ensure stable operation of the unit and extend its service life.

　　一、氣體雜質類型及危害
