A mat 8 of refractory fibers impregnated with catalyst is disposed in front of each emitter 3, 4, which screen emits longer wave lengths of infra-red rays when heated by the emitters. An emission of infra-red rays over a broad spectrum is therefore obtained. In addition, combustible gases contained in the heated space may be oxidized in contact with the screen 8 if the latter is impregnated with catalyst. | |
