Title:
DUAL-FUEL COMBINED CYCLE POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2022/156521
Kind Code:
A1
Abstract:
The present invention relates to the technical field of thermodynamics and thermal power, and provides a dual-fuel combined cycle power plant. There is an air channel outside, which is divided into two paths after passing through a heat source regenerator-the first path is communicated with an air heating furnace and the second path is communicated with a boiler by means of the air heating furnace; there is low grade fuel outside, which is communicated with the air heating furnace; the air furnace is further provided with a primary gas channel in communication with the boiler; there is further a high grade fuel channel outside, which is communicated with the boiler, and the boiler is further provided with a gas channel that is communicated with the outside by means of the heat source regenerator; a compressor is provided with a circulating working fluid channel that is communicated with an expansion machine by means of the boiler, and the expansion machine is further provided with a circulating working fluid channel that is communicated with the compressor by means of a high temperature heat exchanger; a condenser is provided with a compensate pipe that is communicated with the high temperature heat exchanger by means of a booster pump, and then the high temperature heat exchanger is provided with a steam channel in communication with a steam turbine; the steam turbine is further provided with a low pressure steam channel in communication with the condenser; the condenser is further provided with a cooling medium channel in communication with the outside, and the expansion machine is connected to the compressor and transmits power, forming the dual-fuel combined cycle power plant.
