Abstract
Abstract There is disclosed an infra-red process burner, comprised of individual sections rigidly fastened together to provide a generally elongated unit having a common continuous burner face, infra-red generation being controllable in each section and operable in unison to avoid longitudinal areas of material passing therebeneath from receiving less heat than adjacent areas, or individually operable to selectively heat along strips, the virtually instantaneous generation of infra-red heat and termination thereof because of the composition of the burner face, facilitating accurate control of the use of the burner for process treatment of material of widely varying types.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
142 words
In infra-red process burner construction of the class described, in combination, a unitary burner assembly comprising a series of generally rectilinear burner bodies, each having an open face receiving section, said bodies being rigidly fastened together with said sections in alignment, a gas air mixture supply for each body, a single burner face member comprising a fibrous mat of alumina-silica composition having a substantial chromic oxide content extending along said bodies and seated in the face receiving section of each, a face retaining rim extending around the periphery of the assembled bodies and maintaining the face member in place thereon, means to removably fasten said rim in place on said bodies, and means to compensate for heat induced twisting stresses in said rim whereby to maintain said burner face in sealed engagement with the bodies in the face receiving section of each.
Claim 2
Dependent Claim
