Title:
DUAL-FUEL GAS-STEAM COMBINED CYCLE POWER DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/156523
Kind Code:
A1
Abstract:
The present invention relates to the technical field of thermodynamics and thermal power, and provides a dual-fuel gas-steam combined cycle power device. An external low-grade fuel passage is communicated with a combustion chamber; an external high-grade fuel passage is communicated with a heating furnace; an external air passage is communicated with the heating furnace by means of a heat source regenerator; the heating furnace is provided with a gas passage communicated with the outside by means of the heat source regenerator; the external air passage is communicated with the combustion chamber by means of a second compressor and a high temperature regenerator; the combustion chamber is communicated with a gas turbine by means of the heating furnace; the gas turbine is communicated with the gas turbine per se by means of the high temperature regenerator; the gas turbine is provided with a gas passage communicated with the outside by means of the high temperature regenerator; a condenser is communicated with a high temperature heat exchanger by means of a booster pump and an evaporator; the compressor is provided with a steam passage communicated with the high temperature heat exchanger; the high temperature heat exchanger is communicated with the compressor and the condenser by means of a steam turbine and the evaporator, respectively; the condenser is provided with a cooling medium passage communicated with the outside; the gas turbine is connected to the compressor; the gas turbine is connected to the second compressor to form the dual-fuel gas-steam combined cycle power device.
