Abstract
Abstract A radiation tube with a multibranch heat-radiating housing, one of the branches accommodating a burner comprised of a cylindrical air supply shell having inlet and outlet portions, the shell being disposed axially relative to the heat radiating housing so as to form an annular passageway, the passageway having a crossplate provided with one central and a plurality of circumferential apertures for the passage of air therethrough. The burner is further provided with an annular gas header defined by the inlet portion of said air supply shell and a partition wall interposed between the air supply shell and the heat-radiating housing, said partition wall having openings for uniform distribution of gas flow.
