Abstract
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.
