Effects of Changing Operation Modes on Boiler Water

Aug 22, 2018 · The fluctuation of boiler evaporation rate and, in some cases, boiler pressure has an effect on the operation of the BWCP. The BWCP is typically used in forced circulation drum boilers to provide the necessary head (pressure) to overcome the frictional losses encountered in the boiler tubes.
