Both condensate and makeup water are mixed in feed tank from where they are fed to the boiler. As we can see, the quality of feed water depends solely on the quality of makeup water. If feed water is not treated properly, it can result in multiple problems like scale formation or corrosion.

The duty of the boiler feed pump as determined by the boiler and turbine pressure flow conditions, is given by Fig 1.71. Shown on the diagram are the boiler feed-pump characteristics, i.e., the relationships between the head produced by the boiler feed pump corresponding to the particular value of feed flow pumped, and the boiler feed pump speed.

Return condensate is distributed on a tray to generate flash steam. The flash steam helps remove any residual oxygen in the condensate return, as well as the incoming boiler feed water. Large boiler systems with higher boiler feed water rates may utilize a vacuum system. These tend to operate at 212 0F or less.

18/7/2018 · To ensure adequate feedwater flow a boiler must have at all times a slightly higher capacity for feedwater than for steam generation capacity of boiler. This pump is fitted with mechanical seal or labyrinth glands to prevent leakage along the shaft and a balance piston to achieve hydraulic balance and balancing line from first stage to last stage to accumulate the thrust in feed water pump.

10/8/2009 · The condensate, under the effect of gravity goes to the hot well and feed filter tank. If the condenser is under vacuum, extraction pump is used to transfer the condensate to the hot well. Apart from the condenser,the hot well also receives water from the drains of contaminated systems such as fuel oil heating system, oil tank heating, drain cooler, observation tank etc.
