Abstract

A pelletized-biomass combustion device comprises: (a) an elongate upright combustion capsule; (b) a grate element disposed within and bisecting the combustion capsule, (i) the grate element having a first side and a second side and (ii) the grate element open to fluid communication between the first side and the second side; (c) a first combustion air inlet facing the first side of the grate; (d) a second combustion air inlet facing the second side of the grate; (e) a fuel-feed inlet; and (f) a flue-gas exhaust outlet. A method of combusting biomass fuel pellets in a pelletized-biomass combustion device comprising the steps of: combusting pelletized-biomass fuel on a fuel-support surface while feeding combustion air to the fuel-support surface simultaneously through a first and a second combustion air inlet.
