Chinese town domestic garbage accounts for about 1.5 hundred million tons per year, accounts for 30 percent of the total garbage amount of the whole world, and increases at a speed of more than 10 percent each year. At present, the amount of domestic garbage which is not properly treated reaches billions of tons, and the surrounding area and the city of garbage become important obstacles for the healthy development of the economic cycle of the village and the city, and are the toxicomas of the development burden and the environmental deterioration of the village and the city.

At present, the municipal solid waste treatment modes widely adopted at home and abroad mainly comprise: sanitary landfill, composting method, burning method and fermentation biogas production method. The composting process is in an atrophied state. The direct landfill treatment of garbage has the problems that a garbage landfill is a pollution source, mosquitoes and flies are tilled, mice are in disasters, odor is diffused, a large amount of garbage sewage permeates into the underground from the ground surface, and serious pollution is caused to urban environment and underground water sources. The best mode for treating the garbage is incineration, which is a process of carrying out high-temperature thermochemical treatment on the domestic garbage to change the domestic garbage into inorganic ash, and the volume of the domestic garbage can be reduced by 80-95% after the incineration treatment. Small occupied area, flexible site selection and great reduction of garbage transportation cost.

The technical development of the large-scale incinerator is mature, but the large-scale incinerator has high construction cost, high operation technical requirement and high operation cost, and is not suitable for treating the domestic garbage in rural areas in remote mountainous areas.
