ABSTRACT:
A gas-fired radiant heater such as for thawing rail cars and their contents in car barns and the like during freezing weather. The heater has an elongated housing that supports a channel box and an elongated perforated semi-cylindrical mantle supported by the housing over the channel box. The channel box receives a quantity of loosely-packed, fibrous ceramic refractory material that becomes incandescent when heated. The ceramic material has an exposed upwardly facing fibrous surface that defines with the interior of the mantle an elongated combustion chamber. The ends of the combustion chamber are closed and an ignited mixture fuel gas and air is projected into the elongated combustion chamber in the form of a flame jet. The flame jet heats the fibrous ceramic material and the mantle to incandescence so that the upwardly facing surface of the refractory material and the mantle radiate heat energy in a pattern generally normal to the surface of the mantle.
