Abstract
Abstract This invention describes a burner system for burning gaseous fuels in an atmosphere containing oxygen less than that of air and/or in an atmosphere of significant flow velocity. It comprises one or more burner-baffle arrays which may be mounted singly, or in spaced parallel arrangement across the flow of said oxidizing atmosphere. Each array includes longitudinally spaced V-shaped angular baffles placed with the convex surface toward the gas flow. A gaseous fuel conduit connects with the concave downstream side of the baffle within the V angle formed by the side walls. Fuel gas inlet ports are spaced along the length of the conduit. Openings are provided in the walls of the baffles, spaced in direct relation to the positions of said ports.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
182 words
A burner system for burning fuel gas in an oxidizing atmosphere containing oxygen in an amount less than that of air and where said atmosphere has a significant flow velocity; comprising: a. at least one elongated angular baffle means in the path of said flowing atmosphere, the convex side facing said flow, to angularly divert said flow into two angular paths, a plurality of spaced openings in the walls of said baffle, whereby part of said atmospheric flow passes through said openings from the upstream to the downstream side of said baffle; b. a fuel gas supply conduit means positioned in the downstream concave side of said baffle, the axis of said conduit substantially parallel to the walls of said baffle; c. a plurality of ignition ports angularly and linearly spaced along said conduit means to direct the flow of said fuel gas against the inner wall of said baffle; and d. a plurality of firing ports angularly and linearly spaced along said conduit means to direct the flow of said fuel gas into the angular paths of flow of said atmosphere.
Claim 2
Dependent Claim
