Abstract (en)
[origin: WO2014048742A2] The invention relates to a method for operating a gas and steam turbine system (1), wherein the heat contained in the expanded working medium of an associated gas turbine is used in an associated waste-heat steam generator (6) to produce steam for an associated steam turbine (3) having at least one low-pressure part (9) and one high-pressure part (7), wherein a low-pressure stage (14) having a low-pressure drum (48) is associated with the low-pressure part (9) in the waste-heat steam generator (6), wherein gases dissolved in the water or steam are substantially degassed from steam for the low-pressure part (9) from the low-pressure drum (48) and the steam production in the low-pressure drum (48) is varied in order to control the degassing in that heat is shifted within the waste-heat steam generator (6), wherein the heat is shifted in the waste-heat steam generator (6) in that less heat is drawn from the working medium in a medium- (42) or high-pressure stage (22) of the gas and steam turbine system (1).
