Abstract

The invention belongs to the technical field of power generation of hybrid power of an MCFC (molten carbonate fuel cell), and particularly relates to a hybrid power system using a normal pressure MCFC to recover CO2 in exhaust gas of a gas turbine. According to the hybrid power system disclosed by the invention, a gas-steam combined cycle system which does not recover the CO2 is taken as a reference system, and then an integrated scheme utilizing the MCFC to capture the CO2 is proposed. The hybrid power system comprises a gas turbine, an MCFC, an oxygen ion transport film, a high-temperature air turbine, a residual heat boiler and a CO2 recovery unit, and low-CO2 emission of the gas turbine is further realized. Products of an after-combustion chamber of the MCFC only comprise CO2 and H2O, and the loss of power is reduced during the separation and storage processes of the CO2; and the hybrid power system disclosed by the invention fully utilizes residual heat in the high-temperature exhaust gas of the gas turbine and a component thereof, namely the greenhouse gas CO2, as well as the residual heat in the high-temperature exhaust gas of the MCFC and an OTM (optical touch module), and the CO2 in the exhaust gas of the gas turbine can be recovered by utilizing the MCFC with low energy consumption.

Description

technical field [0001] The invention belongs to the technical field of molten carbonate fuel cell (MCFC) composite power generation, and in particular relates to a method for recovering CO in gas turbine exhaust by atmospheric pressure MCFC. 2 Achieving low CO in gas turbines 2 Emissions compound powertrain. Background technique [0002] Molten carbonate fuel cells use electrochemical processes to generate electricity and have high energy conversion efficiencies. Moreover, the high exhaust temperature of MCFC can be recovered by turbine, waste heat boiler and steam water system to form a high-efficiency power generation system with full cascade utilization of energy. And the present invention realizes gas turbine low CO 2 It has unique advantages in terms of emissions: on the one hand, the high-temperature exhaust gas of the gas turbine can provide CO in the MCFC cathode electrochemical reaction with a molar ratio of 2:1. 2 with O 2 , which greatly reduces the CO in gas...
