Boiler Feed Water Flow Rate Requirements Chart | Nalco PTS

Dec 29 2006 · This chart relates boiler horse power to the flow rate in gallons per minute and pounds per hour. In this case we need a demineralizer or softener rated for a maximum flow rate of 28 gpm. It will be less depending upon how much condensate is returned. The next part of this question is what water quality is needed for the application.
