满液式蒸发器低温低应力工况下的设计探讨

Discussion About Design For Flooded Evaporator Under Low Temperature Combined With Low Stress

在满液式蒸发器的设计过程中,应按设计温度、设计压力进行强度计算及应力校核,然后在最低使用温度(加50℃后,应高于-20℃)相对应的饱和压力下进行低温低应力工况的强度计算及应力校核,以确定不必遵循"低温压力容器"的设计参数。

During the process of the design for flooded evaporator,it should be calculated for strength and stress by design temperature and pressure at first,then it should be executed by the saturated pressure corresponding to the lowest application temperature（which add 50 ℃ should be greater than-20 ℃）,so that the design parameters can be confirmed which don′t complied with low temperature vessel.
