Sleeve and damper for oil burner

摘要

A sleeve and damper to increase the efficiency of oil burner performance designed to substantially enclose the flame. The sleeve is heated by the flame to a temperature sufficiently high to assure automatic ignition of unburned hydrocarbons that may result from incomplete combustion of the fuel oil. By controlling the damper operation in conjunction with an adjustable induction air apparatus, unburned hydrocarbons which would ordinarily result are completely oxidized. The resulting completeness of combustion permits the use of oil as a fuel to heat ovens without imparting any odor or taste to the food products being processed therewithin.
