Abstract

PURPOSE:To enable combustion of high complete combustion efficiency without leaving unburnt fuel by detecting CO gas concentration in exhaust gas and adjusting the flow rate of recirculated exhaust gas or the quantity of required combustion air supplied dividedly, using the cncentration value as an adjusting index. CONSTITUTION:In an NOx reducing combustion device, fuel is injected from a fuel burner 2 and burnt with a primary air and a secondary air supplied from air holes 3 and 4. A part of exhaust gas G is drawn by a fan B and returned to a combustion furnace 1 via a pipe 8. To keep the ratio of the quantity of the secondary air flow to the quantity of flow of combustion air A constant, a ratio setter 10 is provided, and to keep the ratio of the quantity of returned exhaust gas flow to the quantity of combustion air A, a ratio setter 11 is provided. In the this case, multipliers 21 and 22 whereto signals based on the output of a CO concentration converter COT are inputted are installed after the ratio setters 10 and 11 and correct the output of the ratio setters.
