COMBUSTION CONTROL METHOD FOR FIRE GRATE TYPE GARBAGE INCINERATOR, AND GARBAGE INCINERATOR

摘要

PROBLEM TO BE SOLVED: To provide a combustion control method for a fire grate type garbage incinerator, and the garbage incinerator for attaining stable combustion of garbage on a fire grate even in the case of performing combustion under a low air ratio, and suppressing toxic substance in exhaust gas and improving heat recovery efficiency.;SOLUTION: Either one or more of garbage feed speed, fire grate speed and an air distribution quantity under the fire grate of primary combustion air are adjusted so that the difference between a gas temperature in a combustion chamber and a gas temperature in a mixing chamber is within a preset range. Further, it is preferable to adjust either one or more of the garbage feed speed and fire grate speed based on the quantity of garbage on the fire grate.;COPYRIGHT: (C)2005,JPO&NCIPI
