Industrial Large Capacity Gas Hot Dip Zinc Galvanzing Furnace with Customized Size
1. Composition of hot dip galvanizing furnace
The zinc galvanizing furnace involves a zinc kettle which is to keep molten zinc liquid.
And the parts are kept in the zinc kettle so as to be galvanized. The hot dip zinc galvanziing
furnace is composed of the following parts: zinc kettle, refractory cover plate, U shape furnace
shell, lining, flue, bottom support, gas burning system, electrical control system, leak alarm, etc.

4. Furnace Burning System
The zinc hot dip galavanizing furnace employs the high-velocity pulse combustion system, and the burners
are placed in the diagonal position of the furnace, and the heat continuously surrounds the zinc kettle from
these two sides. The output power of the combustion engine can reach 170M/sec or more, so the temperature
rises rapidly in a cycling way. The heat conduction transfers heat to every point of zinc kettle, and it also
absorbs the heat generated by the combustion engine. The heat radiates evenly around the outer wall of
zinc kettle, from top to bottom, front to back, so it can increase heating efficiency and generate approximately
the same heat as heat conduction, which greatly increases the service life of zinc kettle. Under pulse control mode,
the output power of each zone can be continuously adjusted from low-power to high-power.
