Energy generating system from solid, fossil fuels - using fluidic bed reactor and pollutants scrubbing prior to application to steam and gas turbine combination

摘要

After fuel combustion in a pressurised fluidic bed reactor, the heat is used for driving a gas and a steam turbine for electric power generation. The flue gases from the fluidic bed combustion are scrubbed of pollutants prior to their supply to the gas turbine. After this scrubbing the flue gases are deeply cooled and then reheated to the gas turbine temperature, prior to intake to the same. Pref. the flue gases are cooled down to approximately 30 deg. K above the dew point temp. prior to scrubbing. Before intake to the gas turbine the flue gases may be heated to 900 deg. C, or below. The flue gas heating may take place in a gas heater as associated to the fluidic bed reactor. Part of the flue gas flow may be separated in front of the gas heater and gas turbine for regulating the fluidic bed and/or the flue gas temp.
