Ask any leading galvanizing furnace manufacturer and they will tell you that pulse fired high velocity furnace is a specialized furnace that is ideally used in galvanizing processes. Powered by pulse firing technology, it offers various productivity and process benefits. And that is why pulse fired high velocity furnace is considered an ideal hot dip galvanizing furnace offering benefits galore. Equipped with high velocity burner, pressure controls, safety valves, temperature controls, and kettle support, the furnace is fabricated to lend the best performance and aesthetics.

Construction and Working

Pulse fired high velocity furnace harness pulse firing and high velocity technology to deliver a fuel-efficient and reliable furnace design. Pulse firing technology works by cycling the burner from high to low in order to meet the required heat demand of the application. There is an air solenoid valve with adjustable maximum and minimum settings that replaces the typical air valve that comes in the ordinary furnace. Now, the burner is ...
... operated at low fire. As the solenoid is energized each time, the burner goes from low fire to high fire operation. This now uses the stirring action and entrainment of the burner, allowing maximum heat transfer by putting it to the situation of best advantage. As the high velocity burners arrive at high exit flue velocity, it creates high turbulence and thereby high circulation of gases inside the furnace which ensure optimized fuel consumption. Pulsing the burner from one zone to another is controlled electronically which simplifies air and gas requirements. Hence, the right combination of pulse firing and high velocity technology creates a condition where there is minimum fuel input but maximum heat transfer, ensuring reduction in operational costs and optimum efficiency.
