New York Low Pressure Boiler COF Practice

The correct pressure for a system using utility street steam is 200 psig at 413°F. This specification relates to the operational standards necessary for efficient and safe distribution of steam. Utility street steam typically operates under higher pressure to ensure that steam can be effectively delivered across substantial distances without significant heat loss or pressure drops.

Additionally, operating at 200 psig allows the steam to maintain a higher temperature (413°F), which is essential for various applications, such as heating, process operations, and creating steam for equipment. This pressure-temperature relationship is rooted in the principles of steam physics, ensuring that the steam remains in a superheated state, preventing condensation in pipes and maintaining the energy needed for application efficiency.

The other pressure options listed are either too low or too high for typical utility street steam needs and may not provide the same effective performance or safety margin required for practical applications involving steam distribution systems.
