ABSTRACT:
An air heater for use in association with a radiant heating tube, the air heater comprising a heat exchanger having a combustion air inlet and a heated combustion air outlet, and a heated gas inlet and a heated gas outlet. The heated combustion air outlet has a transfer pipe connected thereto, an opposite end of the transfer pipe adapted to be connected to an inlet end of a radiant heating tube, and the heated gas inlet to the heat exchanger adapted to be connected to a discharge end of said radiant heating tube. The transfer pipe extending from the heated air outlet of the heat exchanger to an entrance to a radiant heating tube has an air control damper means situated therein. The end of the transfer pipe adapted to be connected to an entrance to a radiant heating tube has a venturi portion therein, an oil nozzle means being situated at inlet of the venturi portion of the transfer pipe adjacent the intake end of said radiant heating tube. Oil supply means are connected to the oil nozzle means and igniter means are situated adjacent to and downstream of said oil nozzle means within the transfer pipe for igniting a mixture of atomized oil and combustion air.
