ABSTRACT:
A wood furnace permits controlled combustion of sectors or segments of wood-type fuels for a high turn down ratio. The primary combustion chamber comprises a refractory base portion for high temperature combustion and an upper portion with a water jacket in heat exchange relationship with the upper portions of the fuel for quenching combustion. A plurality of refractory secondary combustion channels or a single laterally extending or distributed secondary channel leads away from the refractory base portion of the primary combustion chamber. The secondary channels or distributed channel conduct flue gases from different sectors of the fuel, and permit completion of combustion in a high temperature environment. A plurality of flue draft pathways lead from the secondary combustion channels or distributed channel for transfer of heat from the end products of combustion to a heat transfer medium. Separate dampers are provided for controlling the draft in the separate flue draft heat exchange pathways. This permits separate control over combustion of different sectors of the fuel. By appropriate permutations and combinations of control of the flue gas outlets, the rate of combustion and heat output of the furnace may be varied and controlled without sacrificing efficiency of the completeness and intensity of combustion.
