Abstract

Thermal treatment apparatus for combustion, gasification or pyrolysis of material into at least a gas and a solid residue. Material (3) is transported through gasification or combustion chamber (1) at a predetermined rate. The chamber has an air inlet (11) to said chamber, a gas outlet (2) and a pressure transducer (15) for determining the pressure in the chamber. The pressure in the chamber is compared to a target pressure. If the pressure falls outside the target range the volume of air introduced into the chamber through the air inlet is increased or decreased by restricting or encouraging the flow of exhaust gas out of the chamber so as to change the pressure in the chamber. The pressure differential between the chamber and the surrounding determines the air drawn in to the chamber.
