Flame Detector Probe Cooling Fan
Product Description
The flame detector probe cooling fan is an important supporting device in the boiler furnace safety monitoring system (FSSS), widely used in power, chemical and other industrial settings. Its core function is to cool and protect the flame detector probe.
A typical flame detector probe cooling fan consists of two backup cooling fans, a pressure switch, a duct switching baffle, a metal filter, and a control cabinet. The two fans share a single control cabinet, which automatically controls the start and stop of the two fans based on the operating conditions of the cooling air system.
Technical Advantages
1. High efficiency and low energy consumption. Fan efficiency >85%, significantly reducing operating energy consumption.
2. Low noise and low vibration. Noise level <80dB at 1 meter from the fan casing, ensuring smooth operation and low vibration, improving the working environment.
3. Excellent pressure characteristics. It has a very smooth pressure characteristic curve. Within the main operating range, flow rate changes by 5-8 times while pressure changes by only ±5%. It maintains normal pressure even with large flow rate changes and does not experience surge.
4. Redundant Safety Design. Two fans are automatically switched, one in operation and one on standby. The standby fan is interlocked and activated when the outlet main pipe pressure is low, ensuring an uninterrupted cooling air supply.
5. Excellent Technical Parameters. Maximum airflow reaches 5000 m³/h, maximum static pressure 8500 Pa.
Frequently Asked Questions
Q: When should the flame detector cooling fan be started and stopped?A: The cooling fan must be started before the boiler starts operating; after shutdown, it should only be stopped when the furnace temperature drops to room temperature (generally below 80℃), otherwise the probe may be damaged due to high temperature.
Q: What if the cooling air pressure is insufficient?A: When the outlet main pipe air pressure is lower than the interlock pressure value, the standby fan will automatically start; if the pressure remains low, the system will issue an alarm signal, and the filter screen should be checked for blockage or the fan for malfunction.
Q: How to perform daily maintenance?A: The intake filter screen should be cleaned regularly to prevent blockage, the bearing lubrication should be checked, the connections of components in the control cabinet should be checked regularly for secureness, and the cabinet should be kept clean.
