Abstract
Abstract This invention relates to a gas-fired burner of the blast type, comprising a substantially rectangular unit having a burning grid spaced downwardly of the top of the unit. The top has an inwardly projecting lip with spaced notches to prevent blowout from cross drafts and to create a piloting action. Below the grid is spaced a perforated baffle plate for evenly distributing the gas-fired mixture before reaching the burning grid.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
165 words
A gas-fired burner of the blast type comprising a substantially rectangular metallic housing having a circular inlet opening on one closed side and having an inturned metallic lip extending from the rectangular margin of the opposite open side, a perforated metallic baffle plate with relatively large holes spaced from said inlet opening to distribute the air-gas mixture uniformly in the burner plenum chamber, and a burning metallic grid contained in said housing and spaced from said baffle plate, said burning metallic grid having substantially uniformly distributed, relatively large ports of a size of the order of 1/8 inch diameter spaced about 1/2 inch apart, some of which are under said lip, for burning fuel, said lip having a plurality of spaced notches on the inward edge thereof which are slightly offset from said ports, located in spaced relationship under said lip to relieve build-up of temperature, prevent blowouts of the burning flame and to create a piloting action to assure continuous ignition of the burner.
Claim 2
Dependent Claim
