A Tentative Study of the Optimized Operation of Boiler Feed Pumps

The paper presents a theoretical analysis of problems, possibly met with when dealing with operational optimization of boiler feed pumps in fossil power plants, and suggests a way of calculating the pump's shaft power, both when the main power set is running steady or under gliding pressure, under conditions of or under gliding pressure, relative high static pressure heads. Problems, which may easily crop up in constant and in variable speed pumps, running either with a common manifold or in boneblack systems, are being discussed together with how to fix the pumps characteristic parameters and how to design the piping system.
