ABSTRACT:
An electric lamp bulb or electric resistance coil is provided to radiate heat to one or more adjacent surfaces which have an active oxidation catalyst such that fumes and odors in the confines of a room that are drawn over the catalytic surface will be converted to less objectionable products. A catalytic device with an incandescent light bulb type of heating element is of particular advantage in that it can readily be screwed into a lamp base or mounted in other forms of current supplying receptacles and, in addition to a light source, will provide a heat emitting surface for heating the catalyst surface and inducing natural air convection current flow past the catalytic surface. Also, a fume control device which utilizes a resistance heating coil can readily provide both radiant heat and convection heat so that there will be the dual function of fume oxidation from air flow past a heated catalyst surface and radiant heat into a room area. Various types of catalyst coatings and/or catalytic wrappings may be used on the refractory surfaces which will be radiantly heated by the manually mountable-demountable form of bulb or resistance heating element.
