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.
