Abstract
Abstract 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.
