JP3064672U - Ventilation of incinerators - Google Patents

Abstract

(57) [Summary] [Purpose] To promote complete combustion in the combustion chamber. An incinerator having a structure in which an air injection hole is provided in an inner wall of a combustion chamber and more air is injected upward.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention particularly relates to forced ventilation of an incinerator.

[0002]

[Prior art]

 Conventionally, incinerators with a uniform structure in which the amount of air injected from each injection port in the forced ventilation of incinerators is uniform are often used.

[0003]

[Problems to be solved by the invention]

 Conventionally, most of the air injected from the lower layer by the forced ventilation of the incinerator is used for thermal decomposition of the incineration target. The air injected from the middle and upper layers is used for combustion with the gas generated by pyrolysis. However, if too much plastic is added, the amount of gas generated by thermal decomposition will be too large, and the amount of air injected from the middle and upper layers will not catch up, causing incomplete combustion and generating black smoke.

[0004] An object of the present invention is to perform complete combustion even when plastics having a high smoke-generating property are added during operation of an incinerator.

[0005]

[Means for Solving the Problems]

In order to achieve the above object, the structure of the forced ventilation of the incinerator in the present invention has a structure in which the amount of air injected into the furnace increases in the order of lower layer, middle layer, and upper layer.

[Action]

[0007] The gas generated by the thermal decomposition in the incinerator completely burns with a necessary and sufficient amount of air injected from the middle and upper layers, and discharges a colorless and transparent gas.

【Example】

[0008] The hole diameter of the combustion air injection nozzle (1) provided in the combustion chamber of the incinerator is gradually increased as going upward.

[Effect of the invention]

[0009] The gas generated by the thermal decomposition in the incinerator completely burns with a necessary and sufficient amount of air injected from the middle and upper layers, and discharges a colorless and transparent gas.
