Abstract
An improved gas burner construction comprising a gas supply conduit having an outlet. A venturi is located downstream of the outlet and includes a converging section, a throat section, and a diverging section. The converging section of the venturi is spaced outwardly of the gas outlet to provide an annular passage through which air is drawn into the venturi. A helical baffle is disposed within the diverging section of the venturi and is spaced downstream of the throat section. The upstream end of the baffle is secured to the diverging section and the remaining portion of the baffle extending downstream from the upstream end has a substantially uniform diameter and is spaced inwardly from the diverging section of the venturi. A target is mounted on the downstream end of the diverging section of the venturi and includes a central disc-like portion, which spreads the combustible gas-air mixture and provides a short flame pattern.
