What is the purpose of a safety valve in boiler systems?

The purpose of a safety valve in boiler systems is to prevent overpressure. Safety valves are crucial safety devices that automatically release steam or pressure from the boiler when the pressure exceeds a predetermined safe level. This function protects the integrity of the boiler and prevents potential catastrophic failures, such as explosions, which could occur if pressure builds up beyond what the system can handle.

By opening automatically when necessary, safety valves maintain safe operating conditions and ensure that the boiler's pressure remains within the limits established by design specifications and safety regulations. Proper functioning of safety valves is a critical aspect of boiler operation and maintenance, as it directly relates to the safety of personnel and the surrounding environment.

Regulating fuel flow, controlling water levels, and measuring steam quality are important aspects of boiler operations but do not pertain to the primary safety function of relieving excessive pressure.
