Natural Circulation - an overview ScienceDirect Topics

The maximum practical drum pressure for natural circulation is approximately 2750 psig. At higher pressures, the difference in density between the water in the downcomers and the two-phase mixture in the tubes becomes small enough that it is difficult to provide the driving force needed for natural circulation.
