GAS STEAM COMBINED CYCLE CENTRAL HEATING DEVICE AND HEATING METHOD

Title:

GAS STEAM COMBINED CYCLE CENTRAL HEATING DEVICE AND HEATING METHOD

Document Type and Number:

WIPO Patent Application WO/2016/110124

Kind Code:

A1

Abstract:

A gas steam combined cycle central heating device comprises a gas steam combined cycle system, a heat supply network backwater heating system and a thermal station. The gas steam combined cycle system is connected to the thermal station by using the heat supply network backwater heating system. The gas steam combined cycle system comprises a gas turbine (1), a waste heat boiler (2), a direct contact flue gas condensing heat exchanger (3) and a steam turbine (4). The gas turbine (1) is connected to the waste heat boiler (2). The waste heat boiler (2) is connected to the direct contact flue gas condensing heat exchanger (3) and the steam turbine (4). The thermal station comprises a hot water absorption heat pump (5) and a water-water heat exchanger (6). The heat supply network backwater heating system comprises a steam absorption heat pump (7) used for recovering flue gas waste heat and a steam-water heat exchanger (8). The steam absorption heat pump (7) used for recovering flue gas waste heat is separately connected to the steam-water heat exchanger (8), the direct contact flue gas condensing heat exchanger (3), the waste heat boiler (2), the steam turbine (1) and the thermal station. The steam-water heat exchanger (8) is separately connected to the waste heat boiler (2), the steam turbine (4) and the thermal station. Further disclosed is a gas steam combined cycle central heating method.
