Mechanical stoker type destructor and refuse burning method

Abstract

A mechanical stoker type refuse burning furnace, wherein the dehydration mechanical stokers, combustion mechanical stokers and rear combustion mechanical stoker in horizontal position are configured into step-form, so as to lower the height of the main block of the furnace. Furthermore, the primary combustion-air, the secondary combustion-air supplied into the main block of the mechanical stoker refuse burning furnace and the quantity of burning gas extracted from the upper side downstream the main block are adjusted so as to decrease the waste gas displacement from the furnace main block. The invention can facilitate the complete combustion of non-combustible gas and abate the occurrence of NO[X].

Description

technical field [0001] The present invention relates to a skirt-type garbage incinerator for treating waste (hereinafter referred to as municipal garbage) discharged from general households and factories by incineration, and a garbage incineration method using the skirt-type garbage incinerator . Background technique [0002] Where urban waste is disposed of by incineration, motorized grate type waste incinerators are widely used. The motorized grate type garbage incinerator can not only incinerate a large amount of urban garbage continuously and efficiently, but also needs less equipment cost, and has good practical value. [0003] image 3 Shown is an example of the existing motorized grate type refuse incinerator, and this motorized grate type incinerator 40 is made up of following several parts: furnace main body 41; Municipal waste funnel 42; Waste supply propelling machine 43; 44a, combustion motor grate 44b, motor grate 44 composed of post-combustion motor grate 44c...

AI Technical Summary

Problems solved by technology

[0012] However, the methods a, b, and c above all must blow in a large amount of exhaust gas or secondary combustion air A 2 Therefore, there is an increase in the amount of exhaust gas discharged from the furnace main body 41, and the problem of increasing the size of the exhaust gas treatment device installed on the downstream side of the motorized grate type garbage incinerator 40.

[0013] In addition, if the amount of unburned gas such as CO is suppressed by increasing the supply amount of combustion air, the amount of NO cannot be suppressed. x , on the contrary, if the combustion air supply is reduced to suppress NO x If the amount of generation is large, there is a problem of a large amount of unburned gas such as CO being discharged.
