Embodiment Construction

[0023] The present invention provides a pressurized CO with purge gas integrated OTM 2 The zero-emission SOFC / GT / AT / ST compound power system, the present invention will be further described below through the description of the drawings and specific implementation methods.

[0024] The basic system structure diagram is as follows figure 1 Shown: After the air is compressed by the air compressor 1, it flows through the first heat exchanger 2 and the second heat exchanger 3 in turn, and enters the cathode of the SOFC cell stack 4. After the fuel is compressed by the fuel compressor 9, it passes through the third heat exchanger. The heat exchanger 8 exchanges heat and enters the pre-reformer 7 and mixes and reforms the anode exhaust gas of the recycled part of the SOFC cell stack 4, and then enters the anode of the SOFC cell stack 4 to perform electrochemical reactions with the air in the cathode, and through DC / AC conversion The device 6 outputs electric energy. Thereafter, the...

Abstract

The invention belongs to the technical field of pressurized solid oxide fuel cell (SOFC) hybrid-power power generation with zero release of CO2 and particularly relates to a pressurized SOFC / gas turbine (GT) / air turbine (AT) / steam turbine (ST) hybrid power system with zero release of CO2 which is combined with scavenging and integrated with an optical terminal multiplexer (OTM). The invention integrates an SOFC stack system, an OTM system, the GT, the AT, a waste heat boiler, an ST system and a CO2 recovery system to obtain a high-efficiency energy-saving environment-friendly hybrid power system with zero release of CO2. The system energy utilization rate is high; the products of combustion are only CO2 and H2O and the separation and storage of CO2 are facilitated; the power consumption is less; the system has high efficiency while recovering CO2.

Description

technical field [0001] The present invention belongs to pressurized CO 2 The technical field of zero-emission solid oxide fuel cell hybrid power generation, especially a kind of pressurized CO combined with purge gas integrated OTM 2 Zero-emission SOFC / GT / AT / ST hybrid power system. Background technique [0002] The pressurized solid oxide fuel cell uses electrochemical process to generate electricity, which has high energy conversion efficiency, and its exhaust has high temperature and pressure, which can be used for waste heat and waste work through gas turbine, waste heat boiler and steam turbine Utilization, so as to form a high-efficiency power generation system with full cascade utilization of energy. And the solid oxide fuel cell is recovering CO 2 It has a unique structural advantage: when the fuel and air undergo electrochemical reactions, they flow in their respective channels and do not mix directly, avoiding a large amount of N in the air. 2 to CO 2 blending,...
