How to Address Heat Sink Issues in Stainless Steel Desulfurization Fans

Low-noise cabinet-type centrifugal fans for dual-purpose fire protection and desulfurization are used in industrial boilers for desulfurization operations; they do not corrode the blades or affect normal operation. Stainless steel fans are resistant to high temperatures and corrosion. According to manufacturers of low-noise cabinet-type centrifugal fans for dual-purpose fire protection and desulfurization, maintenance of the desulfurization fans is required during operation. To prevent corrosion, consider using corrosion-resistant materials. Equally important for these dual-purpose fire protection and low-noise cabinet-type centrifugal fans is the heat exchanger. If the heat exchanger malfunctions, it must be resolved promptly. So, what is the solution? This situation is caused by gas backflow in the secondary collection system. Since the heat exchanger is not generating heat, it cannot expel air from the exterior of the unit, resulting in no actual heat dissipation. The solution is to close the exhaust pipe to expel the air from the outside of the heat exchanger. If this alone does not work smoothly, check whether the pressure differential is too low or the flow rate is insufficient. The solution is to open the heat exchanger’s water supply valve, close the exhaust pipe, and completely expel the air from the outside of the heat exchanger. If flow cannot be established, verify whether the flow rate is too low or if the backpressure from repeated water discharge is too high. If a dual-purpose (fire protection and ventilation) low-noise cabinet-type centrifugal fan radiator emits a gurgling sound, it indicates water is present on the outside. This type of unit is undergoing secondary collection; since there is gas that cannot be vented, the exterior of the radiator also exhibits abnormal conditions. After implementation, open the exhaust pipe and close the water supply valve. Automatic inspection is typically required, and the issue must be resolved within the specified timeframe. If the radiator is functioning properly, the induction draft fan and axial fan will not exhibit abnormal operation. In severe cases, extra attention is required to ensure the facility’s functionality is maintained. Whether the issue stems from the radiator, corrosion prevention, or other factors, it is a critical problem for any dual-purpose fire protection and cooling low-noise cabinet-type centrifugal fan. Therefore, to ensure long-term use and conserve resources, careful maintenance is essential during operation.
