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. Due to its very short physical length, and controlled combustion volume which has a low peak flame temperature, the fuel burner is especially suitable for transportable aggregate dryers and the like, and produces a higher capacity for such dryers for a given heat output.
