COMBUSTION CONTROL METHOD OF FIRE GRATE GARBAGE INCINERATOR

摘要

PROBLEM TO BE SOLVED: To provide a combustion control method of a fire grate garbage incinerator and the garbage incinerator capable of realizing the stable combustion of garbage on a grate even when the combustion is performed under a low air ratio, and reducing the CO concentration and NOx concentration in exhaust gas.;SOLUTION: The supply amounts of the air and the exhaust gas supplied into a gas mixing chamber as the air for secondary combustion, are adjusted on the basis of the difference between a gas temperature in the combustion chamber and a gas temperature in the gas mixing chamber, the oxygen concentration, the CO concentration and the NOx concentration in the exhaust gas.;COPYRIGHT: (C)2005,JPO&NCIPI
