Abstract
An installation for recovering energy from solid fossil fuels more particularly bituminous coal high in inerts consists of at least one unit in which the solid fuels are converted into gas. A gas-turbine and a steam-turbine are provided to recover the energy from the gases. The gases are freed of dust and desulfurized before the gas turbine. The installation is characterized in that a wet-bottom boiler using the ground fuel is provided with pressure firing, the flue gases therefrom being passed to a gas-gas heat exchanger, the desulfurizing unit and dust-removing unit before being utilized in the gas-turbine.
