四、新能源换热器 1.核电站换热器核电站用的管壳式换热器(又称为大型蒸汽发生器),各国都是作为核能技术的一项重要专题,一直在大力研究和迅速发展。这类换热器一般有三个特点:(1) 一侧流体具有放射性,不允许在换热器内外有任何泄漏;(2)两侧流体都是高温高压;(3) 在上述条件下,同时又要求大型,超大型。因而被称为当

Fourth, the new energy heat exchanger 1. Nuclear power plant heat exchangers Nuclear power plant shell and tube heat exchanger (also known as large-scale steam generator), all countries are as an important topic of nuclear energy technology, has been vigorously studied and quickly development of. Such heat exchangers generally have three characteristics: (1) the fluid on one side is radioactive and does not allow any leakage inside or outside the heat exchanger; (2) both fluids are under high temperature and pressure; (3) under the above conditions, at the same time Also called large, very large. It is called when
