What is the purpose of a pressure relief valve?

To maintain consistent fuel supply

To release excess pressure to prevent boiler damage

The purpose of a pressure relief valve is to release excess pressure to prevent boiler damage. In a boiler system, maintaining appropriate pressure levels is crucial for safe and efficient operation. When the pressure within the boiler exceeds safe limits due to factors like heating or a malfunction, the pressure relief valve automatically opens, allowing steam or water to escape. This helps to reduce the pressure and prevents the risk of catastrophic failures, such as an explosion. It serves as a critical safety device, ensuring that the boiler operates within its design parameters and safeguarding both the equipment and the surrounding environment. Understanding this function is essential for anyone involved in the operation and maintenance of low-pressure boilers, as it directly relates to safety standards and operational effectiveness.
