Steam Drum Internals Evaluation for Lph-2 Boiler in DD-596 Boiler

摘要

Ten internal steam drum moisture separating baffle arrangements were evaluated for possible use in LPH-2 main boilers. The plate type baffle arrangements were of designs which were simpler to manufacture and install in steam drums. An arrangement was found that satisfied the requirements of the applicable specification. Later use of the arrangement on LPH-2 test boiler indicated that the arrangement was unsatisfactory for that installation. In the interest of meeting schedules, it was decided to discontinue development of plate type baffles for LPH-2 and install contrifugal type separators. (Author)
