ABSTRACT:
A heater for combustion of carbonaceous fuels comprising a casing which surrounds and contains the fuel immediately prior to and during combustion and a heat exchanger of unique design which is positioned within the casing. The efficiency of the heater may be increased by providing an improved system for supplying pre-heated secondary air for more complete combustion of partially combusted fuel in the general vicinity of and/or within the heat exchanger. The heater may be of the self-feeding type for combustion of solid fuels such as wood and, in this embodiment, preferably the casing is generally cylindrical and the heat exchanger is approximately centrally located within the casing whereby it extends generally along the casing axis and is spaced a substantial distance from the casing wall.
