4485745 METHOD FOR THERMAL PROCESSING OF SOLID WASTE AND THE APPARATUS FOR CARRYING OUT THE METHOD Gerd-Peter Bracker, Hanns-Helmut Riemann, Bochum, Federal Republic Of Germany assigned to Mannesmann Veba Umwelttechnik GmbH
In a method of thermal solid waste exploitation the pure pyrolysis gases are used for auxiliary heating in combustion and the flue gases from combustion are used for heating in pyrolysis. In a solid waste processing installation the pure gas outlet of the pyrolysis unit is connected to the auxiliary burner of the combustion unit and the pyrolysis reactor is arranged between the flue gas outlet of the combustion unit and a waste heat retrieval unit.
A method and apparatus for reducing pollutant emissions, and in particular, for reducing WOx and particulate emissions, from a spreaderstoker-fired furnace and from a fluidized bed combustor. A combustible material of various sized particles is obtained and those smaller particles which would normally combust during the suspension phase of the spreader-stoker-fired furnace or fluidized bed combustor are separated from the larger particles. The larger particles of combustible material are then introduced into the spreader-stoker-fired furnace or fluidized bed combustor and combusted to produce heat.

An apparatus for neutralizing acidic or acidcontaining pollutants in furnace flue gases comprising a Aue gas duct having an inner pipe suspended therein and arranged so that the flue gases can flow both inside and outside the pipe. Preferably, the gases flow upwards around the outside of the pipe to an outlet zone. Atomizers project into the inner pipe for spraying an ex-
