Garbage incinerator combustion chamber

Abstract

The invention discloses a garbage incinerator combustion chamber and relates to the technical field of environmental friendly electric generation. A combustion chamber front arch and a combustion chamber rear arch are formed by hanging refractory bricks; a combustion chamber rear wall and a combustion chamber front wall are formed by casting materials; a pusher level difference wall, a drying section grate level difference wall, a combustion section grate level difference wall and an ash section grate level difference wall between a pusher, a drying section grate, a combustion section grate and an ash section grate are formed by casting materials; bilateral side walls of the drying section grate, the combustion section grate and the ash section grate are formed by air cooling walls; refractory bricks are symmetrically arranged on bilateral sides of the grates; exteriors of the refractory bricks are provided with insulating bricks; an air cooling wall channel is formed between the refractory bricks and the insulating bricks; the upper end and the lower end of the air cooling wall channel are respectively provided with a hot air outlet and a cold air inlet. The garbage incinerator combustion chamber has the advantages of allowing long-time stable combustion and operation, being simple in operation, not only guaranteeing normal combustion of low heating value garbage and but also guaranteeing high heating value garbage not coking the furnace wall.

Description

Technical field: [0001] The invention relates to the technical field of environmental protection power generation, in particular to a combustion chamber of a garbage incinerator. Background technique: [0002] Municipal solid waste disposal is an important part of urban management and environmental protection, an important symbol of social civilization, and is related to the vital interests of the people. Waste incineration has become one of the main methods of urban waste disposal. [0003] my country's waste classification management level is low, and the waste composition is complex, uneven, high in moisture, high in ash content, and low in waste calorific value. Setting up a suitable combustion chamber furnace wall structure is an important issue to ensure the complete combustion of complex waste. [0004] It is usually used to increase the combustion temperature by reducing the heat volume of the combustion chamber, and the operation period of the waste incineration pl...

Problems solved by technology

[0004] It is usually used to increase the combustion temperature by reducing the heat volume of the combustion chamber, and the operation period of the waste incineration plant is as long as 30 years, and the combustion will be insufficient in the later stage of the operation of the incineration plant; or install a radiation adjustment baffle in the combustion chamber, according to the Calorific value to adjust the baffle angle, the adjustment is more complicated
