Abstract
A method for maintaining a nominal working temperature of flue gases during operation of a PFBC power plant having a pressure vessel with a combustor enclosed therein for combustion of a fuel in a fluidized bed, a gas turbine for receiving flue gases formed during the combustion in the combustor, a compressor driven by the gas turbine for compression of air which is utilized as combustion air during the combustion in the combustor, and a steam turbine driven by steam generated in tube bundles in the bed, includes the steps of burning a complementary fuel in the flue gases generated during the combustion in the fluidized bed downstream of the tube bundle for increasing the flue gas temperature to a nominal level for the process and using oxygen residues in the flue gas as oxidizing agents during combustion of the complementary fuel.
