ABSTRACT:
A flashback inhibiting fuel fired infrared burner has a housing with a base wall, a side wall section extending outwardly from the base wall periphery, and a side opening positioned opposite the base wall. Retained in and covering the housing side opening is a foranimous burner plate structure. An air-fuel mixture supply pipe extends forwardly into the housing interior through a front end of the side wall section into a rear end portion of the housing interior and has an open outlet end. A discharge end portion of the supply pipe is received in an open front end portion of a flow reversing tube having a closed rear end. The supply pipe and flow reversing tube are laterally shrouded within the housing by an elongated baffle member having outlet openings formed in longitudinally extending front and rear wall portions thereof, the total cross-sectional area of the outlet openings in the front longitudinal wall portion being greater than that of the outlet openings in the rear longitudinal wall portion. To increase the radiant heat transfer capacity of the burner plate structure its exterior surface is coated with an emissivity enhancing material.
