COMBUSTION CONTROL METHOD OF REFUSE INCINERATOR, AND REFUSE INCINERATOR

摘要

PROBLEM TO BE SOLVED: To provide a combustion control method of a refuse incinerator, and the refuse incinerator capable of reducing harmful substances in exhaust gas and elongating a service life of a boiler tubes by reducing the variation of a combustion completion position near a gas combustion completion position on a design of the refuse incinerator, or by reducing the variation of O₂ concentration.;SOLUTION: The gas combustion completion position is estimated on the basis of a result of measurement of temperatures of several spots along the gas flowing direction near the gas combustion completion position on the design of the refuse incinerator, and the operation of an operating end of the refuse incinerator is adjusted to determine the estimated gas combustion completion position on a specific position. Otherwise, temperatures of several spots along the gas flowing direction near the gas combustion completion position on the design of the refuse incinerator are measured to adjust the operation of the operating end of the refuse incinerator on the basis of the tendency of variation of temperature difference of the measured temperatures of several spots to achieve the O₂ concentration of the exhaust gas within a specific range at a downstream side with respect to the gas combustion completion position on the design.;COPYRIGHT: (C)2006,JPO&NCIPI
