Title:
DUAL-FUEL COMBINED CYCLE POWER DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/206085
Kind Code:
A1
Abstract:
The present invention relates to the field of combined cycle thermal technology and provides a dual-fuel combined cycle power device. A low-grade fuel channel is provided outside and communicated with a heating furnace; an air channel is further provided outside and communicated with the heating furnace via a heat source regenerator; the heating furnace is provided with a fuel gas channel which is communicated with the outside via the heat source regenerator; a high-grade fuel channel is provided outside and communicated with a second heating furnace; an air channel is provided outside and communicated with the second heating furnace via a second heat source regenerator; the second heating furnace is further provided with a fuel gas channel which is communicated with the outside via the second heat source regenerator; a condenser is communicated with an evaporator via a booster bump; the evaporator is provided with an evaporating channel which is communicated with a turbine via the heating furnace and the second heating furnace; the turbine is provided with a low-pressure steam channel which is communicated with the condenser via the evaporator; a working medium channel is provided outside and communicated with a high-temperature expander via the compressor, the heating furnace and the second heating furnace, and then communicated with the outside via the evaporator; the condenser is provided with a cooling medium channel which is communicated with the outside; the high-temperature expander is connected to the compressor and transmits power, so that a dual-fuel combined cycle power device is formed.
