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.
Claims14
A grate assembly for use in a stove fueled by biomass pellets, the grate assembly comprising:
- a plurality of elongate rods positioned in a parallel arrangement, the plurality of rods comprising subsets of two adjacent rods, the distance between the rods of a first subset being unequal to the distance between rods of a second subset adjacent to the first subset, the distance between the rods of the first subset and the rods of the second subset being sufficient to prevent unburned biomass pellets from falling between adjacent rods.
