Abstract
Adequate cooling of the coolant of a gas turbine of a gas and steam turbine system is assured under all operating conditions, and especially in peak-load operation. The coolant of the gas turbine is cooled by heat exchange with a medium circulating in a separate evaporator loop connected to the steam drum. The cooling capacity is adapted to the operating state of the gas and steam turbine system. An injector connection is provided between a feedwater delivery pipe and the separate evaporator loop.
