PCT No. PCT/SE95/01476 Sec. 371 Date May 19, 1998 Sec. 102(e) Date May 19, 1998 PCT Filed Dec. 8, 1995 PCT Pub. No. WO97/21959 PCT Pub. Date Jun. 19, 1997This invention relates to a method and device for recovery of energy from a medium containing combustible substances even at low concentrations. The method is characterized by raising the temperature of the medium in a regenerative combustor such as a reversal flow direction combustion device wherein the combustion takes place in a warm zone, to the combustion temperature at which essentially all chemical energy of the combustible substances is transformed into thermal energy. The heated medium is then utilized for the production of a wanted form of energy.
