Abstract: A fuel burner for burning liquid and gas fuels having a short combustion volume stabilized by internal circulation of the hot combustion gases and air. A turbo blower supplies a portion of the combustion air to the combustion volume via a swirl plate which produces a rotational motion of the air and fuel. The rotational motion results in a region of less-than-atmospheric pressure in the center portion of the combustion volume which causes recirculation of gases back toward the burner and a stabilization zone near the burner nozzle. Aspiration of external air into the combustion volume is controlled by a short stabilization cone and the resulting combustion volume is small, eliminating the necessity for refractory lined ignition ports and combustion chambers.
