3. General garbage: cardboard, paper scraps, wood chips, leaves, etc.

4. Special wastes: waste oil, waste solvent, sludge, dust collecting pool, paint on iron, mold filter residue, etc.

Domestic waste incinerator

At present, there are many types of incinerators used to incinerate domestic garbage in China. According to the combustion reaction process, they can be divided into direct combustion and pyrolysis gasification combustion. According to the combustion movement and gas-solid mixing mode, they can be divided into mechanical grate furnace, rotary kiln furnace and fluidized bed furnace. The organic content of domestic garbage to be treated in this project is 76.17%, and the inorganic content is 23.83%. The reciprocating push stratified air supply mechanical grate furnace is selected to incinerate garbage. Due to the calorific value content of garbage and the advantages of the design structure of this system, the garbage itself can spontaneously combust without adding auxiliary fuel. Through the convection heat transfer with hot air and the radiation heat transfer of flame and furnace wall, the drying, ignition, combustion and post combustion processes are completed. The combustion temperature and combustion efficiency meet the national standards
