What is a safety valve's role in a boiler?

A safety valve plays a critical role in ensuring the safe operation of a boiler by acting as a pressure relief mechanism. Its primary function is to prevent excess pressure buildup within the boiler system. Boilers operate under high pressure, and if the pressure exceeds a predetermined limit, it can lead to catastrophic failure, including explosions.

When the pressure inside the boiler rises beyond safe levels, the safety valve automatically opens and discharges steam or water, effectively reducing the pressure to a safe range. This ability to release steam prevents potential hazards associated with overpressure situations, safeguarding both the boiler equipment and the surrounding environment.

This function is distinct from enhancing fuel consumption, regulating water temperature, or maintaining water purity, which are important aspects of boiler operation but do not directly pertain to the immediate safety measures taken to manage pressure levels.
