Boiler Feed Water Tank – Description

A Boiler Feed Tank is a storage vessel used to collect and prepare water before it enters the boiler. It combines condensate return and make-up water, heats it to reduce dissolved gases, and ensures a constant water supply to the boiler feed pumps.The tank is usually fitted with steam spargers, vents, level controls, and pump connections to maintain reliable operation. By delivering pre-heated and treated water, the boiler feed tank protects the boiler from corrosion, improves efficiency, and ensures smooth steam plant performance.
