What is the major difference between high-pressure and low-pressure boilers?

High-pressure boilers are defined by their operating pressure, which exceeds 15 psi. This pressure classification has significant implications for design, operation, and safety regulations. High-pressure boilers typically operate at higher temperatures and are designed to handle the stresses associated with such pressure levels. These systems are commonly used in industrial settings where the demand for steam is high and efficiency is crucial.

Understanding this distinction is important, as it influences the type of materials used in construction, the safety mechanisms installed, and the operational procedures required. Operating above 15 psi necessitates more stringent safety measures, including regular inspections and specific operational protocols to ensure safe operation. In contrast, low-pressure boilers are typically limited to lower operating pressures and have different regulatory and operational standards. This clear demarcation between high and low-pressure systems is essential for anyone working with these types of boilers.
