FOSSIL FUEL POWER PLANT WITH INTEGRATED CARBON SEPARATION FACILITY

摘要

As integrated fossil fuel power plant and a method of operating the power plant is provided. The integrated fossil fuel power plant includes a gas turbine arrangement and a carbonate fuel cell having an anode side and a cathode side. The operating method for the integrated fossil fuel power plant includes partially expanding combustion gases in the gas turbine arrangement so that the temperature of the partially expanded combustion gases is optimised for reaction in the cathode side of the carbonate fuel cell, and feeding the partially expanded combustion gases at the optimised temperature to the cathode side of the carbonate fuel cell for reaction in the cathode side of the carbonate fuel cell.

1. An operating method for a fossil fuel power plant comprising a gas turbine arrangement coupled to a molten carbonate fuel cell (MCFC) arrangement, the method including the steps of:
(i) partially expanding combustion gases in the gas turbine arrangement to a predetermined temperature and pressure substantially greater than ambient pressure and temperature and compatible with reaction in a cathode side of the MCFC arrangement; and (ii) feeding the partially expanded combustion gases at the optimised temperature to the cathode side of the carbonate fuel cell for reaction in the cathode side.
