关于HTRI运行结果? 再顶一下,HTRI提示,求高人解答, The maximum process temperature is outside the correlational range of the automatic tube material data bank. The tube metal properties were calculated at the temperature limit. For tube metal number 7 the temperature limit is 21.11 C. Temperature limits are available in the HTRI Xchanger Suite online help file. The boiling fluid mixture pseudo-critical pressure is less than the incremental pressure. Theprogram assumed a ratio of incremental to critical pressure of 0.95 for all boiling fluid heat transferand pressure drop calculations. Check the specified process conditions and physical properties. The areas in the window for multi-segmental baffles are not equal. Check the specified baffle cut and overlap. The program uses the average window area for calculating shellside pressure dropand heat transfer. The pressure profiles given for the cold fluid do not cover the operating pressure range of the heat exchanger. The vaporization profile inside of the exchanger for this run may not be accurate since heat release and fluid properties have been extrapolated. It is recommended that the maximum and minimum system pressures be used as reference pressures. Setting plan error: Channel design pressure is 1029.6 and shell design pressure is 150.0 Maximum allowed is 625 psi.查看更多3个回答 . 1人已关注
