| 摘要 |
The invention relates to a district heating power plant (1) comprising a gas turbine (2) and a waste heat boiler (4) downstream of the gas turbine (2) in the flow direction of an exhaust gas (3) with a hot end (5) facing the gas turbine (2) and a diametrically opposed cold end (6), wherein an evaporator (7) with an outlet (8) is arranged in the region of the cold end (6), and the outlet (8) is connected to a suction medium inlet (9) of a jet pump (10), the propellant medium inlet (11) of the jet pump is connected to a water vapor circuit (12) of the district heating power plant (1), and the outlet (13) of the jet pump opens on a primary side into a heating condenser (14) and on a secondary side is switched into a district heating water line (15), wherein a device (23) for heating an exhaust gas (3) using a heat exchanger surface (24, 27) is arranged upstream of the evaporator (7), wherein the primary side of the heat exchanger surface (24, 27) is switched into a propellant vapor line (28) leading to the propellant inlet (11) of the jet pump (10). |
