Document Type and Number:
WIPO Patent Application WO/2022/206087
Kind Code:
A1
Abstract:
The present invention relates to the technical field of combined cycle thermodynamics and provided a dual-fuel combined-cycle power device, A low-grade fuel channel is externally provided and is in communication with a heating furnace, an air channel is externally provided and is in communication with the heating furnace via a heat source recuperator, and the heating furnace is provided with a fuel gas channel in communication with the outside via the heat source recuperator; a high-grade fuel channel is externally provided and is in communication with a second heating furnace, an air channel is externally provided and is in communication with the second heating furnace via a second heat source recuperator and the heating furnace, and the second heating furnace is provided with a fuel gas channel in communication with the outside via the second heat source recuperator; a condenser is in communication with an evaporator via a booster pump, and the evaporator is provided with a steam channel in communication with a steam turbine via the heating furnace and the second heating furnace and is then in communication with the condenser via the evaporator; an operating medium channel is externally provided and is in communication with a high-temperature expander via a compressor and the second heating furnace, and the high-temperature expander is provided with an operating medium channel in communication with the outside via the evaporator; and the condenser is provided with a cooling medium channel in communication with the outside, and the high-temperature expander is connected to the compressor and transmits power, thereby forming the dual-fuel combined-cycle power device.
