First of all, what is a Boiler? And the simple answer, a typical boiler is a closed vessel in which water or other fluid substance can be heated. You may find an electric or GAS powered boiler in your workplace. In my last workplace, there was a GAS powered boiler and we used water for yarn conditioning. The boiler also uses in Thermal Power Plant for Generating Electricity.
A boiler has several uses in different types of industries. These types of boiler are called an industrial boiler. To maintain smooth operation for this kind of boiler required quality manpower and proper maintenance. It could be a disaster if there is any failure with its operation and perfect maintenance.
In this post I am going to discuss “Why boiler explodes and what should you know to be a perfect industrial boiler operator?”

There is a steel pipe inside the boiler and inside of this steel pipe fire passes through and water or fluid becomes steam. This is the normal operation for any kind of boiler. You will find several water pumps with each boiler. This pump helps to send soft water means a special type of machine that makes normal water to soft water inside the boiler.
Oxygen needs to remove from water and filter the water to remove iron then send it to inside the boiler. Boiler’s life depends on water. Sometimes people do not run the water softener plant because of cost. This is a suicidal decision.
By the water, pump water sends to the boiler and ignite by burning gas or oil inside the boiler. There are two common mechanical safety valves with each boiler. After the 80% completion of the Vassal, the electrical sensor will send a signal to stop the ignition or fire. When the steam level is 30% inside the vassal ignition will start again.
You can change this setting with your requirements. Now if the electrical sensor fails then the mechanical safety valve will open automatically. You may ask “Why boiler explodes due to huge steam pressure when there is three-way to release the pressure automatically?“
Such accidents can occur if the safety valve is not open even the steam pressure is over. Sometimes the safety valve remains installed for years and it is not tested whether it is working or not. Sometimes the valve can be closed when the dirt becomes stagnant and the boiler may explode.

It has been found that the electric safety guard is not automatically operated in the boiler when it should operate. It can happen due to non-maintenance in time. Sometimes the boiler can blast by non trained engineers or technicians.
