ABSTRACT:
In a combined cycle plant boiler an inlet temperature is adjusted or controlled while concurrently modulating the IGV's and the load of the gas turbine and the attemperator of the boiler, and concurrent modulation of the IGV's, the gas turbine load, the attemperator is effected as upon three independent control variables to adjust and/or maintain the boiler outlet temperature independently of steam turbine operation and to maximize gas turbine load control range. Control of the output temperature of one boiler is also managed in relation with the mixed temperature of steam from other boilers fluidly connected to the steam turbines.
