Abstract (en)

[origin: EP0769658A1] The heating gases are conducted along a converter (24) which has conductor ducts (27) open at the bottom. The converter has a structured surface providing a heat exchange surface at least double, preferably quadruple, the size of the active radiation surface. The converter consists of a ridged plate with downward pointing ridges (26) with ridges at least double the height of the thickness of the plate between the ridges. The converter is contained in a hood (10) open at the bottom and under which the heating gases from the burner (15) are conducted. The burner has a burner chamber (16) running along one edge (14) of the elongated hood. The heating gases flow crosswise to the hood's lengthwise direction and flow out at the opposite edge (23). The hood's outside has thermal insulation (11) with at least parts of the inside acting as a reflector surface. The burner has a burner pipe (19) with gas outlets (20) and longer than the burner chamber which has an outlet (18).
