ABSTRACT:
A gas burner produces a homogeneous mixture of gas and air in a short mixing zone by creating turbulence to promote thorough mixing. The burner includes a burner housing supporting a gas distribution tube and an air blower, the distribution tube emitting jets of gas in a radial direction and supporting a baffle plate having a plurality of openings. Air from the blower impinges on the jets of gas to form streams of gas and air that pass through the openings in the baffle plate. A diffuser ring is disposed downstream from the baffle plate and extends radially inward to form a flow constriction. The streams of gas and air contact the diffuser ring and undergo turbulence and the resulting mixture of gas and air passes through the diffuser ring and expands within the interior of a perforated combustion head. The mixture passes through the perforations and when ignited obtains combustion of nearly 100% of the gas and produces a very even flame profile. The burner is easy to manufacture and operates well at very low gas pressures.
