How is a "low-pressure boiler" defined?

A "low-pressure boiler" is defined as a boiler that operates below 15 psi. This classification is important for various reasons, including safety, regulation, and operational efficiency. In the context of boiler operation, the pressure at which the boiler operates dictates the design standards, materials used, and the safety protocols that need to be adhered to.

Low-pressure boilers generally work with lower stress on the system components, which can lead to longer equipment life and reduced maintenance needs. By distinctly defining low-pressure boilers as those operating below 15 psi, regulatory bodies and engineers can specify the appropriate codes and standards that apply, ensuring safe and efficient operations within that pressure range.

Additionally, understanding this definition is crucial for anyone working with such equipment in power engineering, as different parameters govern their operation compared to boilers that function at higher pressure levels. The other definitions do not accurately reflect the standard definition of low-pressure boilers, focusing instead on unrelated aspects of boiler operation or design.
