Abstract

The invention belongs to the technical field of pressurization CO2 zero discharge soild oxide fuel battery composite power, and particularly relates to a pressurization CO2 zero discharge SOFC (solid oxide fuel cell) / GT (gas turbine) / AT (air turbine) / ST (steam turbine) composite dynamical system of integrated OTM (oxyanion transmission film) cathode exhaust producing oxygen. The composite dynamical system is characterized in that an SOFC / GT / AT / ST composite dynamical system which cannot recover CO2 is utilized as a reference system so as to integrate an OTM, a high temperature air turbine (AT) and a CO2 recovery unit to obtain a high-efficiency energy-saving environment-friendly CO2 zero discharge composite dynamical system, and the energy of the system can be fully and effectively used in a cascading manner, and the efficiency is high; and the combustion exhaust is only CO2 and H2O so as to be convenient to separate and collect CO2, the power consumption is less, and the system can keep a higher efficiency after 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, especially relates to a kind of pressurized CO that integrates OTM cathode exhaust gas to produce oxygen 2 Zero-emission SOFC / GT / AT / ST hybrid power system. Background technique

[0002] The solid oxide fuel cell uses electrochemical power generation, breaks through the limitation of Carnot's theorem, has high efficiency, and its exhaust gas has a very high temperature. Under pressurized conditions, it can be used with gas turbines, waste heat boilers and steam The turbines form an efficient power generation system. And because of its unique mechanism: fuel and air are not mixed directly, avoiding the N 2 to CO 2 Blending, which provides convenient conditions for improving energy power system efficiency and reducing emissions. The working temperature of OTM is usually 700°C-1000°C, and the cathode exhaust gas of the battery sta...
