How is a "low-pressure boiler" defined in Minnesota regulations?

A low-pressure boiler, as defined in Minnesota regulations, operates at pressures below 15 PSI. This definition is significant for ensuring that operators and engineers understand the operational limits and safety requirements associated with different categories of boilers.

Low-pressure boilers typically include heating systems for buildings and other applications that do not require high-pressure steam or hot water. By distinguishing a low-pressure boiler as one that operates below 15 PSI, regulatory frameworks can outline specific safety standards, maintenance protocols, and operational guidelines suited to this equipment.

Understanding the pressure limits helps in the safe design, operation, and maintenance of boilers, which is critical in preventing accidents and ensuring the longevity of the equipment.
