Large amount of ventilation inside the crucible kiln can increase production efficiency

The resistance of the stack mainly depends on the density of the stack and the distance of gas passing through the stack path. The thinner the stack, the shorter the path, the smaller the resistance. The denser the stack or the longer the path, the greater the resistance.
To fully utilize the suction function of exhaust equipment, two approaches can be taken. One is to prevent cold air from entering the kiln. The pre heating zone and main flue of the crucible furnace are in the negative pressure zone, and cold air is easy to enter the kiln from an airtight place. After mixing with the flue gas, the tubular furnace is discharged outside the kiln through smoke exhaust equipment.
Reducing system resistance is also very important for increasing ventilation in the kiln. Among the various resistances of gas movement in the crucible furnace, the decisive factor is the stack resistance during billet stacking.
The operation quality of the billet also has a certain impact on the resistance of the billet stack. When stacking billets, it is required to have head to head, seam to seam, straight fire channels, and smooth fire channels. In this way, the resistance can be reduced, and conversely, the resistance needs to increase.
After cold air enters the kiln, it not only reduces the flue gas temperature, but also reduces the intake of air to the kiln cooling belt, which inevitably reduces the air supply for the firing belt to participate in combustion, slowing down the fuel combustion speed and the green body firing speed. The second method for box type furnaces is to use air dampers in a reasonable manner. By increasing the ventilation area of the gate, the resistance to airflow is reduced, and the suction function of the smoke exhaust equipment can be fully utilized.
By adjusting the air brake, the flow direction of gas in the kiln can be controlled, the flow rate of various parts can be adjusted, and waste heat can be fully utilized to preheat the billet, greatly shortening the preheating process and accelerating the firing progress.
