Abstract: Energy is produced from solid fossil fuel high in inerts by burning a fuel under atmospheric pressure with production of smoke gas so that heat is released during the burning and stored in the smoke gas. Thereupon the burning of the fuel, water steam is generated from the heat released and stored in the smoke gas, which steam is used for operation of a steam turbine. The smoke gases are cleaned from noxious materials, compressed and desulfurized. The obtained cleaned gas is provided to cool the smoke gas discharged after burning and to operate a gas turbine. The expanded gas is then used to preheat air which is used for burning the fuel.

Abstract: In an apparatus and process for energy recovery from solid fossil, inerts containing fuels the fuel is burned in a pressurized fluidized bed reactor for operating a gas turbine and a steam turbine. The flue gases of the fluidized bed are cleaned of injurious materials before introduction into the gas turbine. The gases are sharply cooled before material removal and warmed to gas turbine temperatures after removal.

Abstract: A plant for producing power from solid fossil fuels, more particularly bituminous coal, is made up of at least one boiler in which the solid fuels are burned. The plant furthermore has a steam turbine and a gas turbine for producing power from the gas, the gases being cleaned of dust and sulfur before running into the gas turbine. The boiler of the plant is a pressure-fired boiler in which firing takes place in the dry condition, that is without melting of ash.
