Air intake method for furnace of waste incineration boiler and waste incineration boiler equipment

Abstract

The invention discloses an intake method of a garbage incineration boiler hearth and garbage incineration boiler equipment thereof, and belongs to the technical field of garbage incineration boiler operation methods and equipment thereof. The intake method comprises the following steps: a) a primary intake temperature of an air chamber is reduced; and b) the position of an intake pipe on a secondary intake furnace wall is raised. The garbage incineration boiler equipment comprises an air preheating device, a direct connecting pipe, an electric circular air door and a DCS distributed control system; the air preheating device includes a preheating pipe, an air inlet and an air outlet; the direct connecting pipe includes multiple sections of straight pipes and multiple 90-degree shrimp elbows; one end of the direct connecting pipe is connected with a primary intake port of the air preheating device, and the other end is directly communicated with an air chamber intake port below the hearth; the electric circular air door is arranged on one section of straight pipe; the DCS distributed control system can be disconnected or electrically connected with the electric circular air door; and three sets of furnace wall intake pipes are respectively arranged on the front and back walls of the upper and middle parts of the hearth. The Intake method of the garbage incineration boiler hearth and the garbage incineration boiler equipment thereof have the following beneficial effects: the furnace slag caking phenomenon and the furnace slag blockage cannot be generated; and the outlet temperature of the hearth is high, so that the combustion is sufficient.

Description

technical field [0001] The invention relates to an air intake method for a boiler furnace and boiler equipment thereof, in particular to an air intake method for a garbage incineration boiler furnace and the equipment for the garbage incineration boiler, and belongs to the technical field of the operation method and equipment for the garbage incineration boiler. Background technique [0002] At present, the amount of urban and rural domestic waste in my country is hundreds of millions of tons per year, and the cumulative amount is several billion tons, and it is increasing at a rate of 8-10% every year. Only a few of them have been treated innocuously. Serious, it poses a great threat to the environment and human health, and also causes a huge waste of resources. The harmless, volume reduction and resourceful treatment of urban and rural domestic waste is imminent. The traditional way of garbage disposal is landfill, but it is easy to cause secondary pollution of the atmosph...

Problems solved by technology

[0005] The object of the present invention is to aim at the gas intake method of the furnace of the above-mentioned garbage incineration boiler and the prior art of the equipment of the garbage incineration boiler. After the household garbage in the furnace is burned at high temperature, the phenomenon of slag agglomeration occurs, so that the slag cannot be distributed from the air. The plate is normally leaked down, causing slag blockage, and in the upper dilute phase area, the furnace outlet temperature is low, which cannot reach the decomposition temperature of dioxin, and the combustion is insufficient, which will cause a large amount of ash in the flue gas, which will damage the boiler components. Abrasion occurs and the service life is shortened. The gas intake method of the furnace of the garbage incineration boiler and the equipment of the garbage incineration boiler are provided. After the domestic garbage in the furnace is burned at high temperature, there is no slag agglomeration phenomenon, and the slag can be separated from the cloth. The normal leakage of the wind plate will not cause clogging of slag, and in the upper dilute phase zone, the furnace outlet temperature is high, reaching the decomposition temperature of dioxin, so that the combustion is sufficient, and the flue gas will not contain a large amount of ash, and will not Abrasion of boiler parts and prolonging service life
