Abstract

PURPOSE:To suppress the concentration of NOX contained in a combustion generated gas without degrading the efficiency of the incinerator by reducing the grate speed of the incinerator and the quantity of combustion air in priority to the stable control of the boiler evaporation quantity. CONSTITUTION:The quantity of NOX contained in the exhaust gas is constantly measured and monitored by an NOX analyser arranged in the vicinity of an entrance to the chimney of the incinerator. When the NOX value exceeds the upper limit set value set for controlling, each grate (a grate No.1 for cutting and succeeding grates) is retarded or stopped, and simultaneously the quantity of air for combustion is suppressed temperarily. When the NOX value measured has reached the lower limit set value, the original combustion condition is restored. Accordingly, the stable combustion of refuses is performed, the concentration of NOX contained in the combustion produced gas is reduced without almost degrading the efficiency of the devices of the incinerator.
