【Abstract】 The advanced energy-conservation heat exchanger technologies developed by the authors over the past 20 years,including the shell-and-tube exchangers with ring net support,ones with sharp converging-diverging tube and twisted leaf net support and ones with multi-channels in shell,are reviewed systematically for their development course and application in conversion system of sulphuric acid plants. The origin and concepts of these technologies and the key questions solved by them are described. The future trend of the advanced energy conservation heat exchanger technology in sulphuric acid industry is forecast and the development direction is proposed.更多还原
