摘要： A combination power plant is provided with a gas turbine (1) with generator (28) and with steam generators (2, 10) for a steam turbine (6) with generator (29), wherein the exhaust gas of the gas turbine (1) is fed to a first waste heat boiler (2) with superheaters (23, 24), economizer (3), HP evaporator (22) and auxiliary burner (27), and flue gases of a thermal conversion unit are fed to a second waste heat boiler (10). A high-pressure (HP) evaporator (16) with a supporting tube system (13) and HP steam collecting drum (11), on the one hand, and a low-pressure (LP) evaporator (17) with a supporting tube system (14) and LP steam collecting drum (12), on the other hand, are arranged in the second waste heat boiler (10), through which flue gases flow. The P evaporator (16) is connected via a steam line (21) to the first (23) and second HP steam superheaters (24) arranged in the first waste heat boiler (2). An HP steam collecting drum (5) with surface cooler (46) is arranged upstream of the two HP steam superheaters (23, 24). The HP steam superheater (24) is connected to the steam turbine (6) via an HP steam line (20) and the LP evaporator (17) [is connected to the steam turbine (6)] via an LP steam line (25).
