ABSTRACT:
A furnace comprises an enclosure, a hearth plate within the enclosure for supporting combustible material, a first heater element adjacent the hearth plate for initial combustion of the combustible material, a filter disposed above the hearth plate for filtering uncombusted products of combustion of the combustible material, and a second heater element adjacent the filter for final combustion of the uncombusted products of combustion filtered by the filter. A controller controls the first and second heater elements independently.
