Heat exchange in steam generator with low-boiling point fluid

Abstract

The heat transfer processes in the main zones of the steam generator of low temperature power plant are considered. An experimentally substantiated method of taking into account the tube wall effect during nucleate boiling in case of a two-phase flow of case of a working fluid inside the tube is implemented by mathematical modelling. The heat exchange characteristics are presented for each of the zones of steam generator with low boiling point fluid R245fa.
