What is the maximum operating pressure for a low pressure steam boiler?

The maximum operating pressure for a low pressure steam boiler is indeed 15 psi. This designation is significant because low pressure steam boilers are designed and constructed to operate at this specific pressure range, which is typically defined in regulations governing boiler operation.

Operating a steam boiler beyond this pressure can lead to safety risks and compliance issues, as boiler design, safety, and operational standards are established with this limit in mind. The 15 psi threshold allows for efficient and safe steam generation for heating and processes without escalating the risks associated with higher pressure systems. Understanding this limit is crucial for technicians to ensure proper installation, maintenance, and adherence to safety protocols in various settings.
