Abstract

Disclosed is a biomass stove for burning biomass fuel using a combustion furnace. The stove includes a gravity feed fuel holding tank for feeding biomass fuel to the furnace. The combustion furnace includes a primary combustion furnace and a secondary combustion furnace surrounding the primary combustion furnace, as well as a water jacket surrounding the secondary combustion furnace and an air jacket further surrounding the water jacket. A fuel holding device may be in the form of a rotating furnace that includes a support surface with one or more curved vanes thereon for moving gravity fed fuel. An ash removal assembly includes an adjustable ash grate and a fixed ash grate below the furnace. Adjustment of the adjustable grate relative to the fixed grate moves openings into and out of alignment such that ash from burned biomass fuel is output to an ash pan.
