Patent ID: 7530351

Claim:
A pellet fired heating assembly comprising: a) a funnel shaped pellet holder structure having an open top and a bottom opening for gravity feeding pellets; b) an alternating cooling plate and insulator structure having a central opening aligned with said bottom opening of said funnel shaped pellet holder; c) a plurality of spaced air intake plates having openings therebetween forming a primary air intake area, said plurality of air intake plates having a central opening aligned with said bottom opening of said pellet holder; d) a burner housing assembly having a top with an opening, a bottom and side walls and communicating with said spaced intake plates and being positioned below and aligned with said bottom opening of said pellet holder structure, said burner housing assembly having a decomposer grate assembly therein for receiving the gravity fed pellets through said central opening of said spaced intake plates and providing a primary combustion area for burning the pellets; e) an exhaust chute extending from a side wall of said burner housing, said exhaust chute being spacially below said decomposer grate assembly; and f) an adjustable nozzle assembly for the pressurized flow of gas or vapor introduced to said burner housing assembly from a side wall spacially below said decomposer grate and opposite the side wall from which said exhaust chute extends to provide a pressure differential across said decomposer grate and to provide a stream of heated air flow from said exhaust chute.
