Abstract
A continuous flow heating oven of the industrial type used for the heating of ingots, sheet material and the like, which may be of light metal or light metal alloy, includes a burner fired with a liquid or gaseous fuel disposed within a heating chamber. The material to be heated is placed within the oven with the convection air currents generated from the burners directed thereon, with the hot combustion gases produced by the flames. In addition, the exhaust gases are compressed and directed back onto the object to be heated interspersing with the convection air currents originally generated to increase the efficiency of heating the material.
