New York Low Pressure Boiler COF Practice 2025 – All-in-One Guide to Exam Success!

The typical function of a low pressure safety and relief valve is to discharge excess pressure from the boiler system to maintain safe operating conditions. The correct answer highlights that the relief valve usually discharges to a drain, which is designed to safely route the discharged fluid away without creating hazards. This drainage option allows for the control of any liquid or steam that might be released, ensuring it does not accumulate or cause damage to the boiler or nearby equipment.

In contrast, discharging back to the boiler could potentially create dangerous pressure conditions if the discharge is not properly managed. Releasing to the atmosphere could expose personnel and the environment to high-temperature steam or dangerous substances, which is not ideal for safety protocols. Discharging into a containment tank might be used in specific scenarios, but it is not typical for standard safety and relief valves in low-pressure systems, which generally prioritize safe drainage. The design and operation of these systems are focused on preventing accidents and ensuring efficient management of pressure levels.
