Every once in a while, you hear about boilers exploding. There are many different kinds of boilers, which brings to mind the ones you are most familiar with; residential types. While residential boilers can blow, it is usually the industrial kind that cause the explosive accidents. Industrial boilers are massive things, taking up enough square footage that you could store a wrecking crane in its space (if you wanted to). If you are concerned about the boilers in your plant, here are the most common causes of boiler explosions and how to prevent them.
Improperly Installed Boilers
While it is nearly impossible for someone who is qualified to improperly install an industrial boiler, other attempts by other professionals can fail in this department. A DIY job, which is equally unusual for an industrial boiler, but not unheard of, may also be the reason for an improperly installed industrial boiler. Improperly installed boilers will blow, and it is just a matter of time. They are akin to hidden bombs with timers set at an unknown time. To avoid this type of explosion, do not let anyone except a professional from a place like Boiler Services, Inc. install your industrial boiler.
Leaks in the Pressure System
Industrial boilers rely on pressure to produce the right amount of steam. If there are leaks in the system, the boiler works even harder to produce the same amount of steam. The harder it works with less pressure, the more likely it is to fail and eventually blow up. You can prevent this by properly maintaining the boiler every couple of months. Then the technician/contractor will find the leaks and fix them before the leaks have time to cause serious problems.
Too Much Pressure
Conversely, too much pressure can build up in the boiler as well. This is often the result of a blockage in the boiler's pressure delivery system. The potential energy that builds in a gun right before the bullet is released is the closest approximation to what this blockage and excess pressure look like.
If you have someone in charge of reading the pressure gauges on the boilers, he/she needs to watch for the gauge needles to rise dramatically and remain in a high position. This is a very good indication that the boiler affected has too much pressure and that it needs to relieve that pressure. Cutting the power to a boiler this large is not recommended. Ergo, it is a good idea to evacuate that area of the plant and call the contractor/technician to deal with it.
