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

摘要

Development work in the three-effect HTME evaporator at Wrightsville Beach was continued with studies in several areas of design and operation:comparative heat transfer performance of square-,rectangular-,and triangular-pitch tube bundles,influence of steam inlet passage geometry on local heat transfer performance within the bundle,bundle flooding,and feed distribution within a bundle,performance of an HTME evaporator during alkaline and anhydrite scaling,alkaline scale control,and methods of scale removal.
