ABSTRACT:
A radiant heater is provided with a fuel-fired radiant housed in a combustion chamber having a wall with a radiation-transmissive panel. A plenum adjacent the combustion chamber is provided with air under pressure greater than that in the combustion chamber. Air from the plenum is employed as primary combustion air for the fuel-fired radiant, and air from the plenum also is caused to flow cocurrently into the combustion chamber and to provide adjacent the inner surface of the radiation-transmissive panel a constantly replenished pool or cushion of cool air cooling the panel and providing a buffer layer to prevent impingement of hot combustion product gases thereon. The orientation of the heater within a space to be heated may be varied within limits without adversely affecting its operation, and the heater may be made of small size.
