ABSTRACT:
A combustion assembly catalytically oxidizes organic hydrocarbon gases and recovers the heat held by the heated oxidized exhaust generated by such oxidation. The assembly includes a preheater and a catalytic recuperative heat generator which contains a suitable oxidation catalyst. An outside air inlet provides communication between the outside air and the heat generator. The assembly also includes a recirculation duct coupled with a fan which form a loop for storing heated oxidized exhaust for later use, and for moderating temperature losses and gains. A return duct also provides heated oxidized exhaust to the preheater. Variable flow control devices are provided at various positions within the apparatus.
