When a dust collector fire happens, it can be quite a shock. The unsuspected occurrence is usually the product of unfortunate circumstances. Unfortunately, sometimes it can also be the result of neglect. Regardless of the circumstances, it is a good idea to do a thorough check of the system before it is put back into service.
Overall, if the system doesn’t look right when you look at it, then it probably isn’t. Initially check it to see if you think you can see any problem points from afar. It is a good idea to get witness accounts and find out from them if they think they know what the source of the fire could have been. Scorched points in the system that seem discoloured can also be a good indicator as to where the most damage has occurred.
Checking your gaskets is a good idea. Not only might they have been damaged by the dust collector fire but they could also just be a victim of time. Check to see if they have become brittle, hard or powdery. This can lead to cracks and this can allow moisture in or air out of the system. The compressed air piping should be assessed paying special attention to the clamps, tubing and hoses. Damage in pulse pipes is rare but it is a good idea to check for wear and tear while you are at it.
If the tube sheet has signs of heat damage or warpage it can lead to the seals on the filters not sealing properly. This is a damage prone area so take some extra care. The hopper should be assessed checking particularly for debris accumulation and molten metal that can build up on the walls, angles and blades that will essentially disrupt the discharge process. The entryways will need to be assessing to see if there is any warping of the ports or doors.
Housing walls need to be assessed for distortion. Any contact with the filter bags can cause premature wearing. If the distortion is really bad then the housing will need replacing. Unfortunately, in this extreme situation there is no way to straighten anything out. It has to be a clean swap with a replacement. Any of the equipment that is downstream will also need to be checked for debris. Especially on bearings and fan blades. The rupture panels will also need a check to ensure they are still intact.
When it comes to a dust collector fire the fact is – it started for a reason. When you do your checks to see if the system can be put back into service it is a good idea to find the fire source.
