Abstract

The invention relates to a boiler which is used for incinerating household garbage and generating steam to be used for steam supply and electricity generation. According to the technical scheme, the waste incineration boiler with a furnace dedusting device comprises a steel frame, a boiler chamber and a fire grate, wherein the boiler chamber is composed of a hearth, a burned ash chamber and three smoke flues, and a horizontal flue and a flue with a U-shaped tail portion are arranged behind the boiler chamber. By mean of the technical scheme, the compound-type waste incineration boiler is capable of guaranteeing timely drying, full burning and burning out of the household garbage which is low in calorific value, high in moisture and high in ash specification and effectively reducing flying ash amount in smoke.

Description

technical field [0001] The invention relates to a boiler for incinerating domestic garbage and generating steam for steam supply and power generation. Background technique [0002] In recent years, my country's industry has developed rapidly, the population has been concentrated, and cities have expanded rapidly, resulting in more and more domestic waste. Garbage management has become an urgent and unavoidable problem. Using the waste incineration treatment method can effectively reduce the waste capacity, save land, is not easy to cause pollution, and can generate steam for steam supply and power generation. [0003] In view of the advantages of waste incineration in "reduction, harmlessness and resource utilization", it has become the mainstream way of waste disposal. The main components and volume of flue gas from waste incineration are related to the composition of waste, combustion method, and flue gas treatment equipment. In order to better incinerate domestic waste...
