In the process of urbanization, garbage is once a burden for urban development as a product of urban metabolism, and many cities in the world have the situation of surrounding garbage. With the increasing emphasis on environmental issues, energy conservation and environmental protection have become the subject of development in various countries, and have begun to provide industrial development opportunities for garbage disposal. The annual growth rate of garbage all over the world is 8.42 percent, and the growth rate of Chinese garbage reaches more than 10 percent. Worldwide, 4.9 million tons of garbage are produced each year, and only China produces nearly 1.5 million tons of municipal garbage each year. The accumulated quantity of domestic garbage in China reaches 70 hundred million tons. Under such tremendous waste pressures, it is reasonable to believe that the waste disposal industry will become the star industry in the future.

At present, two main methods of garbage disposal are landfill and incineration. Although the landfill cost is low, the landfill garbage is not subjected to harmless treatment, and a large amount of bacteria and viruses remain; hidden troubles such as heavy metal pollution of the methane and the like are hidden; the garbage leakage liquid can pollute underground water resources for a long time, so the method has potential great harm and can bring endless future troubles to descendants. The method not only does not realize the resource treatment of the garbage, but also occupies a large amount of land, which is a dangerous practice of reserving pollution sources to descendants. Landfill is prohibited in many developed countries at present. The competent departments at all levels of the government of China gradually know the problems of the treatment technology and tend to forbid and eliminate the behaviors.

The waste incineration mode has higher environmental protection requirements on ash and tail gas, and further can only make a large article on the combustion efficiency and tail gas purification efficiency of the incinerator.
