Abstract
This paper traces the evolution of the high-pressure feed pump in this country over the last decade, concentrating on its application in land-based, steam power plant.
The influence of the choice of feed system and the effect of mounting feed water flow rates, pressure, and temperature on the design of the feed pump is discussed.
Advantages and disadvantages of the various methods of driving a feed pump are enumerated and attention given to the reasons for the adoption of higher running speeds, and the means whereby high-speed pumps have been accommodated in view of their higher net positive suction head requirements.
Material selection and component design is also considered in the light of the changing requirements brought about by larger size, more onerous operating conditions, and higher running speed. Glands, axial thrust balancing devices, impeller mountings, controls, and high-pressure joints, are each briefly discussed.
