Abstract
A pellet fuel burner includes a compact thermally insulated firebox for providing hot gases to a boiler, furnace or dryer. The apparatus includes a grate that includes a reciprocating arm for removing clinkers and ash from the grate. Pellet fuel feed is provided by a hopper that is isolated from the firebox by an airlock. A combustion air manifold is provided around the firebox to preheat primary and secondary combustion air.
