What is the maximum capacity for steam of a boiler installed under class 3B license?

The maximum capacity for steam of a boiler installed under a class 3B license is correctly identified as 5,000 pounds of steam per hour. This licensing classification is designed to ensure that operators have the necessary skills and knowledge to manage systems within specific capacity limits.

A class 3B license allows operators to handle boilers that can generate steam at this defined threshold because it encompasses boilers of moderate size and complexity. The regulation behind this capacity ensures safe and efficient operation, reflecting the capabilities required in managing thermal systems while adhering to safety standards in the industry.

Understanding these parameters is crucial for anyone involved in hydronic and process piping, as they dictate the level of responsibility and the operational limitations associated with various boiler types.
