Filed:

Mar 27, 1992

Appl. No.:

7/858556

Inventors:

Timothy R. Carlson - Seattle WA

International Classification:

F23H 704

US Classification:

126174

Abstract:

An apparatus for preventing ash build-up and clinker formation of a particulate fuel mass in a stove includes a grate having a plurality of openings therein and on which the particulate fuel mass resides. A bottomless container retains the particulate fuel mass on the grate. The grate is reciprocated with respect to the bottomless container and the particulate fuel mass such that the position of the grate openings is altered relative to the particulate fuel mass to channel stove air flow through various portions of the particulate fuel mass.

Abstract:

A pellet fired stove has a rotating fuel feed cylinder for reliably and uniformly transporting pellet fuel from a hopper to the stove's combustion chamber. An open upstream end of the rotatable hollow feed cylinder communicates with a hopper containing solid fuel, such as wood pellets. The downstream end of the cylinder opens into a fuel chute leading to the combustion chamber. The fuel pellets from the hopper spill into the rotating hollow feed cylinder and form a sloping pellet bank within the cylinder. The rotation of the cylinder agitates the sloping bank of fuel sufficiently to cause a uniform quantity of fuel per cylinder revolution to be separated from the fuel bank and discharged from the cylinder into a combustion chamber.
