Product Overview | Tempest® 4442 Burner
In most industrial furnaces, recirculation of products of combustion (poc) can contribute significantly to speed of heating and temperature uniformity. A fan usually provides recirculation in low temperature ovens and dryers. But fans are not practical for higher temperature furnaces and kilns. Excess air systems can accomplish recirculation, but they are fuel wasteful; e.g., 30% excess air in a 2000°F furnace requires 24% more fuel than stoichiometric firing.
• 600°F preheated air; up to 800°F with -H model • Available with refractory and metal tiles • Wide air/fuel ratio flexibility
APPLICATIONS Ceramic Tunnel and Periodic Kilns
Heat Treat Furnaces Car Bottom Furnaces Scrap Preheaters Galvanizing Tanks Crucible Furnaces Air Heating and Drying
True high velocity gases entrain and recirculate seven or more times their own volume, eliminating need for fans or excess air.
Tempest burners achieve superior uniformity by increasing penetration into the center of multi-piece loads.
