Fourth Report on Horizontal-Tube Multiple-Effect (HTME) Process Pilot Plant Test Program.

摘要

Results of testing of the three-effect HTME Pilot Plant at the Wrightsville Beach Test Facility are reported for the period from May 1971to January 1972. During this period,additional heat transfer data were obtained. Boiling coefficient on the outside of tubes and condensing coefficient inside of tubes were determined. A correlation was developed for the condensing coefficients. Photographic studies were made to determine the nature of bubble formation and growth on the outside surface of tubes. The variation of heat transfer coefficients across the HTME tube bundle was measured. Increased heat transfer coefficients,obtained at temperatures above 190F,are reported for tubes enhanced on the outside surface. Tests were conducted to determine the effectiveness of the brine distribution system to obtain uniform distribution of brine over the tube bundle,and results are reported comparing the brine distribution above and below a deep tube bundle.
