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 equally or unequally spaced rods. The design of the rods serves to prevent the ash and clinkers from accumulating on the grate in mounts that could reduce the flow of combustion gas into the fire. In one embodiment, an ignitor rod is provided as one of the spaced rods in the grate assembly. By applying power to the ignitor rod, the rod is raised to a sufficient temperature to ignite unburned biomass pellets in proximity to the ignitor rod.
