Abstract
A method of operating a gas turbine in which variations in power requirements are accomplished by varying the rate of steam injection into the combustor while maintaining the temperature of the fluid flowing to the turbine at a constant value. The steam injection flow rate is varied by varying the pressure in the evaporator of a HRSG that receives exhaust gas from the turbine. Preferably, the flow area of the turbine is increased so as to allow the use of especially high rates of steam injection.
