What defines a low-pressure boiler?

A low-pressure boiler is defined specifically by its operating pressure. In this case, the definition stipulates that a low-pressure boiler operates at 15 psi (pounds per square inch) or less. This classification is important because it determines the regulatory requirements, safety measures, and operational protocols that must be followed when managing the boiler system.

Boilers that operate above this pressure are classified differently, typically as high-pressure boilers, which involve different standards for operation and maintenance. Understanding these classifications helps ensure that operators maintain compliance with safety regulations and perform appropriate inspections and maintenance practices suited to the type of boiler they are operating. This classification also helps operators grasp the nature of the system they are working with, ensuring they are adequately prepared to handle emergencies or operational issues.
