Title:
DUAL-FUEL COMBINED CYCLE STEAM POWER DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/141611
Kind Code:
A1
Abstract:
The present invention provides a dual-fuel combined cycle steam power device, which belongs to the technical fields of thermodynamics and thermal powers. An external low-grade fuel channel is in communication with a boiler, an external air channel is further in communication with the boiler by means of a heat source regenerator, and the boiler is further provided with a gas channel in communication with the outside by means of the heat source regenerator; an external high-grade fuel channel is further in communication with a second boiler, an external air channel is further in communication with the second boiler by means of a second heat source regenerator and the boiler, and the second boiler is further provided with a gas channel in communication with the outside by means of the second heat source regenerator; a condenser is in communication with a steam turbine by means of a boost pump, an evaporator, the boiler and the second boiler; a compressor is provided with a steam channel which is in communication with the steam turbine by means of the boiler and the second boiler; the steam turbine is further provided with a low-pressure steam channel which, after being in communication with the evaporator, is in communication with the compressor directly and is in communication with the condenser by means of a second steam turbine; and the condenser is further provided with a cooling medium channel in communication with the outside, and the steam turbine is connected to the compressor and transmits power, which form a dual-fuel combined cycle steam power device.
