Problems solved by technology

However, the use of existing mechanical grate incinerators for waste disposal has encountered the following problems: due to the high ash content, low combustible components, and high water content of urban domestic waste in my country, and with the change of seasons, the composition of waste varies greatly. Especially in winter, the calorific value of the garbage i

Abstract

The invention discloses a waste incineration boiler. The waster incineration boiler mainly comprises a hearth and a combustion chamber, three flues and a tail flue which are connected to the hearth sequentially, wherein the upper part of the hearth is provided with a boiler barrel, and the lower part of the hearth is provided with a grate; and a slag and ash discharging device is arranged on the lower part of the grate. The waste incineration boiler is characterized in that the grate is a reciprocating multi-row grate; an auxiliary burner is arranged on the side wall on the lower part of the hearth; a start-up burner is arranged on the rear wall on the lower part of the hearth; and a high-temperature gas-air preheater and a superheater are respectively arranged in the three flues from bottom to top sequentially. The invention makes household waste with low heating value, high moisture content and high ash content sufficiently combusted and burnt out in the waste incineration boiler. The waste incineration boiler can effectively inhibit generation of harmful gas. Steam generated by the boiler is used for generating electricity and supplying steam. The waste incineration boiler realizes reduction, hazard-freetreatment and recycling of waste treatment furthest.

Description

technical field [0001] The invention relates to a technique for recycling garbage, in particular to a garbage incineration boiler that incinerates garbage and generates steam for power generation and steam supply. Background technique [0002] With the development of urban economic construction and the improvement of people's living standards, the amount of domestic waste generated is increasing year by year. Currently, domestic waste disposal methods include sanitary landfill, incineration and composting. The incineration method with the characteristics of reduction, harmlessness, and resource utilization is currently the best garbage disposal method. It is an effective way to deal with municipal solid waste through the development of waste incineration boilers for waste incineration. [0003] At present, the main types of waste incinerators are: mechanical grate incinerator, fluidized bed incinerator, gasification melting furnace and rotary kiln incinerator. Among them,...
