New York Low Pressure Boiler COF Practice

What is the required pressure for a system using utility street steam?

1. 150 psig at 350°F

2. 200 psig at 413°F

3. 250 psig at 400°F

4. 300 psig at 440°F

The correct answer is: 200 psig at 413°F

The requirement for a system using utility street steam is typically based on the steam pressure and temperature necessary to meet the demands of the facility or process. Utility street steam is commonly supplied to commercial and industrial applications, where specific pressure and temperature specifications are necessary for optimal system performance. A pressure of 200 psig at 413°F is aligned with industry standards for steam systems, where pressures and temperatures are needed to ensure efficient operation and safe transfer of steam. Higher pressures can increase the risk of leaks and safety concerns, while lower pressures might not be sufficient for certain applications. The selection of this pressure reflects a balance between operational efficacy and safety regulations. In the context of the other answer choices, while they provide higher pressures and temperatures, they may exceed typical requirements for utility street steam, leading to unnecessary complexity and potential regulatory issues. Always, the parameters chosen for steam systems should fall within the guidelines established for operational safety and efficiency, which makes 200 psig at 413°F the preferred and correct answer.
