What is a common safety issue associated with high-pressure boilers?

Low water levels in high-pressure boilers can lead to significant safety hazards. This situation can result in overheating and damage to boiler components, such as the boiler tubes. When water levels drop below safe operating levels, the remaining water can become superheated, leading to the risk of a steam explosion or severe damage when the tubes become exposed to excessive heat without sufficient water to absorb it. Maintaining proper water levels is crucial for the safe operation of boilers, as water acts as both a coolant and a pressure control medium.

In many cases, low water levels may arise from leaks, malfunctions in automatic water feed systems, or operator error, making diligent monitoring and safety protocols essential. Regular checks and maintenance help prevent this issue, as does adherence to operational controls and safety systems designed to indicate low water levels before they become critical.
