    Patent number: 5997277
    Abstract: This 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.
