What function do safety valves perform in a boiler system?

Safety valves in a boiler system play a critical role in maintaining operational safety by preventing overpressure. These valves are designed to automatically open when the pressure within the boiler exceeds a predetermined limit, allowing steam and gases to escape. This action helps to prevent dangerous conditions that could lead to explosions or other failures due to excessive pressure.

By venting excess pressure, safety valves ensure that the system remains within safe operating parameters. They are essential components in the overall safety management of high-pressure boilers, as they directly respond to hazardous increases in pressure that could occur due to malfunction or operational errors.

While options that suggest increasing pressure, regulating temperature, or providing steam release may have some relevance to boiler operations, they do not accurately capture the primary and critical function of safety valves. The essence of a safety valve is solely focused on preventing overpressure and ensuring safety within the boiler system.
