摘要： A portable pellet fired heating element for mounting to a grill or stove and comprising a gravity fed pellet holder, a unitary tubular structure having a burner, an air intake and an exhaust chute. Fuel may be supplied to the pellet holder by various supply means such as a conveyer, ramp, scooped, held in bulk in a hopper, and like pellet supply structures and methods. Fuel is fed to the air-cooled insulated burner area onto a decomposer grate, which defines the primary combustion area and which is partially open to the atmosphere for air intake. An adjustable high-pressure flow of gas or vapor is introduced to the primary exhaust chute below the decomposer grate to create a low pressure flow above the grate and which upon ignition, cause flames to be pulled into the pellet mass on the grate. In operation, air from the primary air intake maintains hot charcoal in the primary combustion area, and the secondary combustion area provides a steady flow of wood gas that mixes with a predetermined or adjustable amount of air supplied by the secondary air intake to maintain the flame. The super heated gasses and any ash are provided to the grill or stove by means of the exhaust chute. For cleaning purposes, an electrical/mechanical device may be provided to move the decomposer grate or to provide a sudden burst of high gas pressure.
