ABSTRACT:
An improved gas-fired radiant heater is disclosed, particularly useful in drying continuous web materials, wherein a partially compartmentalized manifold chamber is formed beneath an extended series of porous ceramic tiles for evenly distributing a predetermined gas-air mixture of fuel so that upon ignition there is provided a continuous burning surface along the entire length of the tiles. A plurality of baffle members are disposed throughout an elongated manifold housing to compartmentalize lower portions of the manifold chamber and thereby permit the proper flow of fuel through the heater to generate a more uniform radiant heat field. An air jacket assembly surrounding the manifold chamber is further provided and includes an outer casing into which cooling air is injected and circulated throughout the length of the heater. The casing is formed to provide an elongated air gap along either side of the tiles and an angled deflector is mounted over and above each air gap to vent and direct the circulated air away from the radiant tiles for better and more efficient cooling of the heater structure. In a system configuration, a plurality of the heaters are parallelly mounted and disposed oppositely facing each other in a staggered arrangement for effective drying of the web material when passed therethrough.
