How To Maintain A Forced Draft Fan?

 



Industries face various challenges when selecting the appropriate fans for boilers or furnaces. Choosing an inappropriate fan causes severe issues, leading to unwanted and costly repairs. Moreover, there is also a chance for higher pollutant emissions. The best option is to choose a forced-draft fan. These fans are placed at the system’s inlet and ensure that a positive pressure is created by pushing in fresher air. This is how the life expectancy of the furnace is increased. 

Maintaining a forced draft fan 

These are the points stating the maintenance of the forced draft fans: 

Inspection on a regular basis 

Conducting visual inspections every week is more effective. Detailed inspections are conducted monthly. Hence, it is better to inspect these fans as doing so increases their longevity. Check for wear and tear, loose parts, and signs of damage. Moreover, you can obtain professional assistance for inspecting forced draft or centrifugal fans. 

Cleaning 

Once the dust accumulates inside the fans, the airflow is hindered. Moreover, the fan's performance is hampered. Hence, it is better to clean the fan blades, housings and filters. In the future, there will be no chance of dust accumulation. 

Lubrication 

Using an old lubricant inside a force draft fan can lead to equipment damage. In a few cases, it can lead to a catastrophic failure. Hence, it is better to replace the older lubricant and replace it with a newer one. 

Inspecting the belts 

It often happens that the belts of the forced draft fans experience wear and tear. Wear and tear lead to a loss of tension and a decrease in the fan's speed. Therefore, it is advisable to inspect the belts to ensure they are functioning properly. This matter is often overlooked, which can lead to trouble. 

Monitor vibration 

It is also better to monitor the vibration level of the forced draft fans. Monitoring the vibration level can resolve the developing issues as easily as possible. What you can do is to look for the alignment and balance issues once the vibration trends rise. Increasing the frequency of vibration can cause some serious issues. 

Schedule maintenance 

A manufacturer will provide a maintenance schedule. Ensure that you follow that maintenance schedule. Keep in mind that different fan models have varying schedules. It is clearly mentioned in the product manual. 

What can be done additionally? 

The force draft fan manufacturer can recommend some lubricants. It is better to implement them. To minimise downtime during emergencies, consider storing spare filters, belts, and bearings. Train your staff to ensure that they handle the fans properly. Try to consider appropriate techniques for maintenance. It is better to analyse the level of vibration, which allows you to identify potential aspects. If overlooked, then these aspects can become a serious issue.

Maintaining a force draft fan is part of the daily routine. You need to maintain it so that it functions well. The best manufacturer will offer the right fan for various industries. Search for manufacturers online to view their products. The products are available at an affordable price.
