There are many unfortunate accidents that occur during the installation of boilers. There is not anyone definite cause but sometimes even small events gather up to end up in an accident. Though there are many causes behind these accidents the human error remains the topmost reason behind the boiler installations accidents. This is the reason why the installation team is suggested to remain alert and vigilant all the time. Many people think that this issue is not a serious one, but on an average 2,334 accidents occur due to boiler installations per year. If you were doing your research regarding this topic then luckily you have landed on the right page. This article will guide you through some terrible incidents that usually happen during boiler installations.
Fuel Explosions
Without any doubt, fuel explosions are one of the most common factors which contribute towards an unfortunate accident during the boiler installation. The main reason for fuel explosions is fuel-rich mixtures. Sometimes fuel-rich mixtures that are high in concentration fail to burn completely. When they do, it can happen in an explosive or rapid matter. It can occur at any time whenever insufficient air is provided to help burn the unburned fuel. This is the reason why it is suggested not to add any air in the smoky furnace. It is advised to first trip the unit, purge it properly and then one should investigate and correct the problem.
External Load Causes Cracking
Cracking Due to an External Load is one of the biggest issues when it comes to boiler installations. As the name describes, an excessive amount of load is provided which turnouts to be disastrous. The most common cause behind this is poorly functioned support system which is poorly designed as well. This occurs at an instance when the load is transferred from the support to all the way to nozzles. These occur during the addition of equipment or sometimes even when connecting pipes. Though there are many other causes as well it can be sorted due to the visual examination as well. It can be installed in the nozzle and then one can identify and sort the problem more accurately and easily.
Low-Water Conditions
Many boilers are natural circulators of water and they don’t take the help of pumps for the water circulations. These mainly take help and rely upon cold and hot water to provide them the circulation. Over time, as the water is removed, it removes the heat which leads to the temperature being increased and at the end leading to a boiler steam drum. At this moment, sufficient heat is transferred and proper steam is produced. To control the boiler drum is not a piece of cake and even if a person has the best control system in town it can’t guarantee that they would prevent the low water condition. It can be disastrous if it takes place. These mainly occur due to control valve failure, drum level controller failure, safety valve lifting, failure of drum level controller, and much more.
