What is a common cause of boiler failure?

A common cause of boiler failure is poor maintenance or neglect, which often leads to inadequate water treatment. When a boiler operates without proper maintenance, issues such as scale buildup, corrosion, and the presence of impurities in the water can occur. Inadequate water treatment can result in the water quality deteriorating, which can lead to overheating, pressure drops, and ultimately mechanical failure. Regular maintenance checks, including water testing and treatment, are essential to ensure that the boiler operates efficiently and safely, preventing catastrophic failures that can disrupt operations and pose safety risks.

The other options do not directly address the primary factors that contribute to boiler failures. For instance, excessive weight during installation is more of an installation concern than an operational one. Similarly, regular checks on fuel type, while important for efficiency, are not as critical to the functioning of the boiler as proper water management. Proper ventilation is necessary for safe operation but does not prevent boiler failure in the same way that routine maintenance and water treatment do.
