ABSTRACT:
This invention relates to a method and apparatus for the extraction of heat and smoke from a fuel burn in a firebox. The design is for the firebox exhaust area to be wrapped with its own hot exhaust gases, for smoke extraction, and then, for heat extraction, have all of the outer surface of a stove, fireplace or furnace exposed to said hot exhaust gases. Such a wrap-around design burns smoke form said exhaust gases, holds a high temperature in the firebox area, for good combustion, and increases the efficiency of heat extraction by using all of the outer surface of the stove, fireplace or furnace as a high temperature heat exchanger.
