Abstract
A stove using biomass pellets as fuels includes a stove body, wherein the stove body comprises a firebox; hopper, wherein the hopper is fixed above the stove body; and feed tube, wherein the top end of the feed tube which is connected to the hopper is fixed outside the stove body, the bottom end of the feed tube which is connected to the firebox crosses the stove body. The stove using biomass pellets as fuels solves the problem that common pellet stoves usually transfer the fuels to the hearth using a screw feeder or other feeding equipment, which expend too much cost.
