Combustion controller for stoker type incinerator

Abstract

A combustion control unit for stoker-fired combustion furnace including air flow rate regulating means (30a) for regulating of the rate of air flow to air flow channel (30); temperature detecting means 35(35a) for detecting of the temperature of air-mixed recirculating gas; and combustion control means (60) adapted to have the value of detected temperature of air-mixed recirculating gas inputted from the temperature detecting means 35(35a), to compute, on the basis of the value of detected temperature, the area of flow channel of air flow rate regulating means (36) allowing the temperature ofair-mixed recirculating gas to become a preset target temperature and to control the flow rate regulating means (36) at the value of flow channel area computed.

Description

technical field [0001] The present invention relates to a combustion control device for a charging type incinerator. The primary air is introduced from the bottom of a feeder for inputting garbage, industrial waste, etc. The upper portion of the combustion chamber performs secondary combustion. Background technique [0002] The feeding type (スト一カ) incinerator is an incinerator configured as follows. It is equipped with a feeder configured by alternately arranging the grate of the fixed section and the movable section. While stirring and advancing the garbage (incinerated materials) put into the hopper, the garbage is dried in the drying zone arranged on the upstream side of the feeder, and the primary air is injected into the next main combustion zone, and the main combustion is carried out, and the most downstream The ember burning area on the side burns the remaining amount of embers. [0003] Patent Document 1 (Japanese Patent No. 3582710) provides a technique in which,...
