（一）Shell and tube heat exchanger design procedure管壳式换热器设计步骤
1、Identify service (process unit, heat exchanger
type as cooler, reboiler, condenser, chiller, steam
generator etc、)、定义服务：（工艺设备，换热器如：冷却器，再沸器，冷凝器，深冷器，蒸汽发生器等等）
2、 Identify heating medium and cooling medium;定义加热介质和冷却介质
3、 Check hot / cold side is heat balance or not? if
not, how much differ? less than or equal to5%, reminder
process guy and continue to design; more than5%, reject
process datasheet and stop、校核热/冷侧是否热平衡？如果不是的话，相差多少？小于等于5%时，工艺计算提示继续设计，超过5%，返回并结束设计。; S3 t1 B& f9 a、 s2 m
4、 Is temperature cross? How many "e" shells in
series required? (Normally2 shells in series can be adapt
to about10 degree temperature cross、)温度交叉？要求多少E型壳体？（通常双壳程适用于10℃的温度交叉）
第 1 页 共 1 页 5、 Select the TEMA type (normally project should
have a heat exchanger thermal design guide、)选择TEMA标准（通常，每一个换热器都有热力设计指南）
6、 Select tube material and shell material (if not
specified by material engineer guy)、选择管程材料和壳程材料（如果不是材料工程师具体指定的）; `8 @0 t/ {$ l, m# n"

7、Select tube length (normally16 or20 for horizontal
exchangers;10 or12 for vertical thermosyphon reboilers、)选择换热管长度（通常水平布置换热器用16’或者20’，垂直热虹吸再沸器用10’和12’）)

8、 Select the start shell id, number of tubes and
number of tube passes、选择壳体内径，换热管数量和管程数%

during the thermal design phase assures that the final
shell-and-tube heat-exchanger design is accurate and
minimizes lost time and labor for making revisions
later、 热力设计阶段遵从ASME标准能确保管壳式换热器的最终设计的准确性，将浪费的时间缩至最低，为后期版本的修改减少工作强度。; J, c! yf& yThe classical division between
