Abstract
A burner for mixtures of air and gas has a generally closed burner body extending along an axis. There is an entrance portion at one end of the body open to the atmosphere and an exit portion at the other end of the body having a second opening to the atmosphere. The body is generally defined between a relatively flat top plate and a converging, relatively flat bottom plate and between curved side plates to establish a rectangular enclosure. The entrance portion decreases in transverse cross-sectional area away from the entrance opening to a high-velocity zone having a minimum transverse cross-sectional area from which the exit portion flares between the central zone and the exit opening with a substantially constant cross-sectional area. A gas tube extends along the axis through the entrance opening and into the entrance portion to a point somewhat short of the high-velocity zone.
