烟气换热器的选型探讨

Discussion of flue gas heat exchangers selection

介绍了管壳式换热器、回转式GGH换热器、板式换热器、MGGH换热器和热管换热器的结构、应用范围与优缺点,从传热效率、积灰和腐蚀等方面分析了烟气换热器选型的注意事项,最后对烟气换热器选型过程进行示例说明及分析。

Structures,application ranges and advantages and disadvantages of shell and tube heat exchanger,rotary GGH heat exchanger,plate heat exchanger,MGGH and heat pipe exchanger are briefly introduced.Heat exchangers selection precautions are analyzed in terms of heat transfer efficiency,fouling and corrosion.Finally,an example is given to illustrate and analyze flue gas heat exchanger selection process.
