Which device is used with condensate and MUF to regulate water quantity in the system?

• A. Deaerating Feed Tank (DFT)
• B. Water Treatment Unit
• C. Feedwater Heater
• D. Isolation Valve

Answer: (A)

Regulating water quantity in a condensate and makeup water system is handled by a reservoir that collects returns, blends in makeup water as needed, and feeds the boiler with treated water. The Deaerating Feed Tank does this by receiving condensate from the system and MUF, deaerating the water to remove dissolved gases, and supplying a steady feedwater supply to the boiler via the feed pump. This combination keeps the system at the proper water level and flow. The other devices don’t regulate quantity: a Water Treatment Unit improves water quality, not the amount of water in the system; a Feedwater Heater increases the temperature of the feedwater to improve efficiency, not the quantity; an Isolation Valve simply stops or allows flow and doesn’t continuously regulate the overall water quantity.
