With the increasing garbage output in China, the reasonable treatment of garbage becomes more important. At present, three main methods for garbage disposal are available: landfill treatment, incineration treatment and composting treatment. The incineration method is a method of putting garbage in a high temperature furnace to fully oxidize combustible components therein, the generated heat is used for power generation and heating, although the simple incineration method can realize garbage treatment at the fastest speed and does not occupy a large amount of land, the air is polluted by discharged gas after the garbage is incinerated, and the residue of the incinerated garbage still needs secondary landfill. The composting method has poor effect on reducing the garbage and has higher cost. The landfill method occupies a large amount of land resources and is easy to cause secondary pollution to water and soil.

The use of the garbage cracking gasification furnace increases the efficiency of harmless treatment of garbage, and the generated combustible gas can be continuously utilized.
