DEVELOPMENT OF VERY HIGH PRESSURE WATER-JET FOR CLEANING NAVAL BOILER TUBES

Mechanical brushing has been the standard method for removing soft deposits from the watersides of steam generating tubes in U. S. Naval boilers. Problems with that method such as limited deposit removal, equipment breakage and jamming of brushes in tubes led to a program to develop more rapid, effective, and trouble-free methods of soft deposit removal. The use of very high pressure water evolved out of that program. This paper describes the research and development conducted to improve water-jetting and apply it to naval boiler tube cleaning. It describes the development of optimum pressures, flow rates, nozzle and flexible lance configurations, control methods, degree of deposit removal, cleaning procedures, safety considerations and many other aspects, including the Navy-wide adoption of this method. Also mentioned are other potential applications of water-jetting for cleaning, removal of tight deposits and coatings, and for machining and surface finishing operations.
