A Test Condenser to Measure Condensate Inundation Effects in a Tube Bundle.
Abstract
A test condenser was designed and constructed to provide a means to evaluate the effects of condensate inundation on enhanced condenser tubing. Fifteen horizontal tubes were used to form a square inline tube matrix three tubes across and five tubes high with a spacing to diameter ration of 1.5. The center column of active tubes was made of 16 mm O.D. half hard copper. They were flanked by full round 16 mm O.D. stainless stell dummy tubes. Smooth tubes were utilized to validate the operation of the system. A new method of data reduction was developed to increase experimental accuracy. This was accomplished by measuring actual tube wall surface temperatures so that the steam side heat transfer coefficient could be calculated directly. This approach replaces the complexity and inaccuracies of the Wilson Plot technique. Validation of system operation was accomplished using steam at 253 mm Hg absolute. Recommendations to improve the test condenser are provided. (Author)
