  • Installation for recovering energy from solid fossil fuels, more particularly bituminous coal high in inerts
    Patent number: 4425757
    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.
