<p>A method and apparatus are provided for gasifying/pyrolysing material containing organic matter including introducing the said material into a treatment chamber (2) and heating the material by passing a flow of hot gas (30) containing less than 5% oxygen through the chamber (2) so as to cause the material therein to gasify or pyrolyse. In a first mode of operation, the gas (30) is passed through the chamber (2) at a first velocity. The apparatus comprises a means (20, 21) for temporarily increasing the velocity of the hot gas (30) such that in a second mode of operation the velocity of the gas (30) exiting the means (20, 21) is temporarily increased. An increase in the efficiency of gasification and/or pyrolysis is possible using such methods.</p> |
