Classification of heat exchangers
Thread Content
There is a heat exchanger whose shell side is cooled by steam water. During operation, the inlet temperature is 133°, the outlet temperature is 78°, and the operating pressure is 0.3 MPa. What is the temperature condition of the shell side?
The medium in the shell side is steam cooling water; when classifying it, the properties of the medium, as well as the operating pressure and temperature, are usually taken into consideration. Based on the data you provided, the working pressure is 0.3 MPa; at this pressure, the steam is saturated steam, with a saturation temperature of around 133 degrees. Since the outlet temperature is 78 degrees, this means that the steam has condensed in the shell side; therefore, the shell side can be considered as a heat exchange process involving phase change. However, to determine the detailed classification of heat exchangers (such as fixed-tube plate, floating-head, U-tube, etc.), more information on the design and construction of heat exchangers is required. Without more information, it is not possible to specifically classify the types of heat exchangers. .
