Title:
DUAL-FUEL GAS-STEAM COMBINED CYCLE POWER EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2022/148329
Kind Code:
A1
Abstract:
The invention provides dual-fuel gas-steam combined cycle power equipment and relates to the technical field of thermodynamics and thermal power. Externally, a low-grade fuel is in communication with an air heating furnace. Also externally, a high-grade fuel channel is in communication with a combustion chamber. Also externally, an air channel is in communication with the air heating furnace via a heat source regenerator. The air heating furnace also is provided with a gas channel in communication with the external environment via the heat source regenerator. Externally, the air channel is in communication with the combustion chamber via a compressor and the air heating furnace. The combustion chamber also is provided with a gas channel in communication with a gas turbine. The gas turbine also is provided with a gas channel in communication with the external environment via a high-temperature heat exchanger. A condenser is provided with a condensate pipe in communication with the high-temperature heat exchanger via a booster pump and the high-temperature heat exchanger in turn is in communication with a steam turbine via a steam channel. The steam turbine also is provided with a low-pressure steam channel in communication with the condenser. The condenser also is provided with a cooling medium channel in communication with the external environment. The gas turbine is connected to the compressor and transfers power. This forms the dual-fuel gas-steam combined cycle power equipment.
