New York Low Pressure Boiler COF Practice

Wet bottom boilers should be set above the floor by at least how much?

1. 10 inches

2. 12 inches

3. 14 inches

4. 16 inches

The correct answer is: 12 inches

Wet bottom boilers are designed to operate with a reservoir of water in the bottom section, which helps to maintain the boiler's efficiency and safety. The requirement for these boilers to be set above the floor by a specified amount serves several important purposes. Setting the boiler 12 inches above the floor provides adequate clearance for maintenance and inspections, ensuring that operators can safely access all necessary components. This clearance also helps to prevent flooding or water accumulation at the base of the boiler, which could lead to corrosion, rust, or other damage to the hydrostatic components. Furthermore, having the boiler elevated mitigates the risk of physical damage from debris or water vapor that may be on the floor, contributing to the longevity and reliability of the equipment. It is a standard practice and regulatory requirement for ensuring the safe operation of wet bottom boilers that enhances both maintenance and operational integrity.
