Abstract: A radiant burner that has a hollow body with a closed rear and a peripheral wall extending forwardly from the rear to define an open ended chamber. There is an outwardly extending, planar spacing flange on the front end of the peripheral wall. A perforated diffuser plate extends across the chamber in a plane located rearwardly from the end of the wall. The plate has a forwardly directed flange around its perimeter and an outwardly extending marginal edge which lies against the spacing flange. A primary screen consisting of a plurality of layers of fine bias cut mesh extends across the open end of the chamber with its edges overlying and adjacent to the front surface of the edge of the plate. A reverberator grid which has a planar body and a backwardly extending border flange is located in front of the primary screen with an outwardly extending edge of its flange adjacent the surface of the edge of the primary screen and its main body spaced forwardly from the primary screen by its flange. The layers of the primary screen and the reverberator grid are spot welded together at certain points. The central portion of the primary screen is dished forwardly toward the reverberator grid. Retaining lips on the spacing flange of the body are folded over inwardly against the front surface of the edge of the reverberator grid flange for retaining the diffuser plate and the primary screen and reverberator grid in place in the burner. There is an inlet for combustible gases into the chamber behind the diffuser plate.

Abstract: An infra-red heat generator having a generally cup-shaped body which has an open front end. A perforated diffuser extends across the body lying in a plane parallel to and spaced from the open front end. The diffuser defines a mixing plenum in the rear of the body behind the diffuser. There is an inlet into the plenum for a combustible gas mixture. The percentage of open area of the diffuser is such that during operation a positive pressure is maintained in the plenum. The diffuser is held in place by a spacer which fits into the open end of the body. A multi-layer primary screen lies across the open end of the body. The layers of the primary screen are welded to each other in an orientation with the elements of each layer overlying, in part, the openings of the adjacent layer and the layers are contiguous throughout. The edges of the primary screen lie against the front edges of the generator body which define its open end and the center of the primary screen is convex relative to its edges. The elements of the screen layers are deformed against each other at their crossing points to provide substantial areas of surface contact therebetween. A centrally convex reverberator grid is positioned in front of the primary screen by a spacer that extends between the edges of the screen and the grid. The diffuser, primary screen, grid and spacer are all held in position by a cap which has an inwardly directed lip overlying the edges of the grid and a main flange which telescopes over the front of the generator body and extends around the edges of the primary screen. A retainer is wedged between the outer surface of the body and the main flange of the cap to hold the parts in assembled position.
