Feedtanks for steam boilers

Overview

What is a feedtank?
A feedtank, in a steam plant, is normally the meeting place for cold make-up water and condensate return.

A correctly designed feedtank should utilize the heat energy from the returning condensate to reduce thermal loss and effectively promote circulation to assist in constant water conditions

Feedtanks for steam boilers Incorrectly designed feedtanks tend to not take advantage of the returning condensate to promote natural agitation and retain heat within the tanks water.
If precious heat energy is lost due to inefficient tank design then the result may end in further oxygen being retained in the feed water, higher chemical costs, increased fuel and boiler operation costs

Benefits

The incoming source water would normally require pretreatment to help reduce the reliance on water treatment
chemcials and to help prevent scale formation on heat transfer surfaces.

This subject is best left for water treatment specialists as the pre-treatment and chemical program should be considered for independent applications.
Cold water make up, returning condensate and other energy recovery systems need to encourage mixing improving thermal efficiency and assisting in dissolved gas removal.
