Abstract
PURPOSE:To contrive to reduce the heat loss carried away with exchaust gas by a method wherein the exhaust amount is suppressed to necessary minimum amount without generating incomplete combustion by stably burning a combustion equipment at the air-fuel ratio nearer to its limit than usual. CONSTITUTION:A main controlling unit 37 receives the signal indicatig the steam pressure of a boiler from a pressure gage 31 and sets the desired value of the steam pressure of the boiler and the PID (proportional-plus-integral-plus-derivative) constant. A limiter 43 calculates the amount of variation of a manipulated variable DELTAT12=T1-T2, wherein T1 is the manipulated variable of the boiler at the time and T2 is the predetermined manipulated variable of the boiler. When the amount of variation DELTAT12 lieswithin the allowable value of variation DELTAT, T1 is adopted and when DELTAT12 lines out of DELTAT, T2+ or -DELTAT is adopted. Furthermore, the output of an excess air ratio setting circuit 46 is applied to an excess air M correction circuit 47 in order to calculate alphaXDELTAT or alphaXDELTAT12 in case that the amount of variation T is positive or in order to calculate betaX¦DELTAT¦ or betaX¦DELTAT12¦ in case that the amount of variation DELTAT12 is negative. When the corrected excess air ratio is determined at the correction circuit 47, said corrected ratio is applied through a decision circuit 48 to an air flow rate setting circuit 49.
