Consulting - Specifying Engineer | Basics of boiler selection

Sep 15, 2017 · Boiler feedwater pumps should be capable of supplying the boiler with water at a pressure at least 3% higher than that of the drum operating pressure. An evaluation of the line routing from the pump outlet to the drum inlet should be performed and pressure losses calculated to determine the proper discharge pressure.
