Problems solved by technology

At the same time, the fly ash content in the flue gas after incineration is high, the boiler ash is heavy, and the ash cleaning maintenance period is short
[0007] 2. With the increasing amount of garbage generated and piled up like mountains, the amount of garbage treatment must be effectively increased in order to meet market demand
[0010] Existing gasification incinerators, such as the following two invention patents: Multi-column segmented drive compound domestic waste incinerator (ZL200710092508.9) and two-stage waste incinerator (ZL201010268376.2) Unsolved problems: heat treatment of waste The mode is relatively backward, just drying-burning-burning, the process of solid combustion releasing heat; the thermochemical reaction in the furnace is dominated by oxidation reaction, supplemented by reduction reaction, which is easy to produce secondary pollutants; when garbage is burned in the furnace, the peroxygen coefficient Large, large amount of primary air and secondary air supply, high dust content in flue gas, great impact on heat energy recovery system and flue gas treatment system, easy to accumulate dust, large amount of flue gas, reducing heat conversion efficiency; Without a separate gasification furnace and ember furnace, waste can only be processed in batches, and large-scale continuous gasification and incineration of waste cannot be realized, and the amount of waste treated is small

Description

technical field [0001] The invention belongs to the technical field of solid waste incineration treatment, and in particular relates to a mechanical grate type garbage gasification incinerator and a boiler power generation system thereof. Background technique [0002] The existing waste treatment technologies mainly include incineration, sanitary landfill, composting, and waste recycling. Among the conventional waste treatment technologies, incineration has the advantages of obvious reduction effect, complete harmlessness, small land occupation, utilization of waste heat energy, and less secondary pollution, which meets the strategic requirements of my country's sustainable development. However, with the continuous improvement of environmental protection requirements at home and abroad, how to strengthen the control of secondary pollution is particularly important. Therefore, waste pyrolysis and gasification incineration technology is gradually pushed to the road of industr...
