What is the primary purpose of safety valves in boilers?

The primary purpose of safety valves in boilers is to release excess pressure. Safety valves are critical safety devices designed to prevent the pressure within the boiler from exceeding safe limits. When the pressure in the boiler rises beyond a predetermined level, the safety valve opens automatically, allowing steam or gas to escape. This function is essential to avoid catastrophic failures, such as explosions, which can occur if the pressure continues to rise unchecked.

By allowing excess pressure to vent, safety valves help maintain the integrity of the boiler system and ensure safe operation, which is paramount in boiler management. This action is fundamental for the protection of both the equipment and personnel working in the vicinity of the boiler.
