Abstract
Abstract An infra-red radiant burner is disclosed which uses a porous refractory board matrix that is supported by two pairs of frame members that provide a ledge upon which the matrix lies and a peripheral lip means that grips the edge of the matrix. The frame members together with a flat sheet will form between the flat sheet, the frame members and the matrix, a gas-air mixture chamber, while the frame members are made hollow to receive a non-combustible gas which is directed outwardly along a narrow exit path along the sides of the matrix.
