ABSTRACT:
A radiant tube heater has a tubular arrangement with an air duct portion forming a combustion air passage and a radiant tube portion which is heated by and surrounds a laminar flame. An inlet end of the air duct portion receives combustion air from a blower. A burner assembly mounted in the air duct portion includes a burner nozzle and a burner head for mixing gas and combustion air, this head having an inlet portion and an outlet portion wider than the inlet portion. A perforated restricting plate is mounted in the air duct portion and extends around the burner head. Air holes in this plate are sized and distributed so that the plate increases flow of combustion air through openings formed in the side of the inlet portion and allows combustion air to flow in the annular passage between the outlet portion and the air duct portion.
