Title:
RADIATION HEATER
Document Type and Number:
Japanese Patent JPS6014006
Kind Code:
A
Abstract:
Radiant heater having supported porous refractory panel through which combustion mixture passes and on the surface of which mixture burns as it emerges, has a narrow stream of incombustible relatively cold gas like air pumped through the panel adjacent the support to act as a barrier seal and minimize the leakage of combustible gas around the margin of the panel, and the consequent burning of such leaking gas, which burning can damage the marginal support and cause flashback. Panel can have edges held on tubular frame sealed to a back plate to provide a simpler heater construction with combustion mixture plenum defined by back plate and frame, and with cold gas supply to the tubular passageways in frame.
