General Description:
A regenerative burner system consists of a preheated air burner coupled with a heat exchanger. The heat exchanger is an insulated container of refractory shapes which store heat, and the burner doubles as the tube exhaust. The regenerator is "charged" by passing exhaust gases through it. When it is saturated with heat, exhaust gases are shut off and combustion air is blown through it, preheating the air, which mixes with gas in the burner, heating the tube. Because of the alternating firing / heat storage cycles, regenerative burners must be installed in pairs. These systems produce extremely high combustion air temperatures (within 300 - 400°F of tube temperature) and high thermal efficiencies.

Principal Applications: Continuous Enameling Furnaces and Continuous Steel Heat Treating & Galvanizing Lines
