Stoves fueled by biomass pellets are provided with a grate assembly that supports the pellets for combustion and directs combustion gas into the fire. The grate assembly includes a passive grate of unequally spaced rods. The design of the rods serves to prevent the ash and clinkers from accumulating on the grate in amounts that could reduce the flow of combustion gas into the fire.

Combustion grate with rods for pellet fueled stove

Stoves fueled by biomass pellets are provided with a grate assembly that supports the pellets for combustion and directs combustion gas into the fire. The grate assembly includes a passive grate and a moveable elongate blade spaced above the upper surface of the grate to direct ash and clinkers through a plurality of elongate slots in the grate. The design of the planar plate and the movement of the blade serves to prevent the ash and clinkers from accumulating on the grate in amounts that could block the elongate slots and reduce the flow of combustion gas into the fire.
