Seeking advice on heat exchange area
Thread Content
Suppose there is a heat exchanger that needs to be designed, with all the necessary basic parameters given, such as the inlet and outlet temperatures of the feed water, as well as its enthalpy； Steam temperature, hydrophobic temperature, enthalpy ； Wait, wait, wait. So how does one calculate the heat exchange area? I checked HEI and GB151, but it seems there are no calculation formulas... or did I miss them? I would like to ask the seniors for advice. I would be very grateful if you could let me know the standard name of * that should be learned.
One must first assume the heat transfer coefficient K, then make rough calculations based on that assumption, and finally adjust the coefficient
It is recommended to find a book on heat exchanger design; such books usually provide detailed procedures, but many parameters require looking them up in tables, and following the steps isn’t very difficult

The K value, which represents the overall heat transfer coefficient, is determined by factors such as the viscosity, flow rate, and thermal conductivity of the medium, as well as the structural characteristics and material composition of the heat exchanger. It is also closely related to scaling agents present in the material and heat carrier, as well as the rate of scaling. Although various sources provide information on this topic, the range of values can be quite wide; for example, the K value for a certain material under specific operating conditions may range from 500 to 1300 W/M2·OC. This makes it difficult to make decisions regarding design choices. Therefore, it is very important to take into account practical experience when determining the K value.
You haven’t studied \"Principles of Chemical Engineering\" or \"Heat Transfer\", have you? Find a textbook and take a close look at it; if you have any more questions, then post and discuss them.
