PCT No. PCT/GB96/02169 Sec. 371 Date Apr. 27, 1998 Sec. 102(e) Date Apr. 27, 1998 PCT Filed Oct. 25, 1996 PCT Pub. No. WO97/15641 PCT Pub. Date May 1, 1997A process for the production of heat energy from solid carbonaceous fuels is disclosed which comprises subjecting the carbonaceous fuel to substantially anaerobic pyrolysis in at least one first zone and thereafter transferring the char resulting from the pyrolysis to a second zone which is segregated from the first zone or zones. The char is subjected to gasification in the second zone by introduction of primary combustion air, optionally with steam and/or recycled exhaust gas. The off gases from the second zone and the pyrolysis gases from the first zone or zones are thereafter subjected to secondary combustion and the first zone or zones is heated by heat derived from the secondary combustion. Ash is removed from the bottom of the second zone.
