What is the normal steam pressure for low pressure boilers?

• A. 10 psi
• B. 15 psi
• C. 20 psi
• D. 25 psi

Answer: (B)

The normal steam pressure for low pressure boilers is typically set at 15 psi. This standard is widely accepted because it provides a safe and efficient operating range for most low pressure steam applications, particularly in heating systems. At this pressure, the steam produced is adequate for transferring heat without excessive pressure that could lead to safety hazards or inefficiencies in the system. Steam at 15 psi has a corresponding saturation temperature of approximately 250°F, making it effective for various heating needs, including residential and light industrial applications. Operating at 15 psi allows the system to function within safety guidelines established by industry standards and regulations, ensuring reliability and performance while minimizing risks associated with higher pressure systems.
