Heat exchanger
Thread Content
Given parameters: the inlet and outlet temperatures of the shell-side steam are 205 and 95 degrees Celsius, respectively. The operating pressure is 0.75 Mpa. The inlet and outlet temperatures of the tube-side cooling water are 38 and 97 degrees Celsius respectively. The operating pressure is 1.6 Mpa. The cooling water flow rate is 120 t/h. Design a U-tube heat exchanger. Should latent heat be considered? I seek advice from experts. Does this belong to the condenser or the heater? What is the steam flow rate? And how is the shell-side heat transfer coefficient calculated?
Of course, the latent heat must be included. The heat transfer coefficient can only be estimated by knowing the heat transfer area, wall thickness, and material. From what you described, this is a heater that uses steam to heat the water inside the U-tube. I don’t understand why it has to be used in this way. Is it because high purity water is required? Or can’t the steam be directed into the water instead? Is it perhaps because the water pressure is higher than that of the steam?
Are you using waste heat to heat the boiler water?
I don’t know either; it’s my graduation project
Could you help me check if steam is used for both import and export? Is there no phase change? There’s no need to calculate in segments
It’s probably something like this: EDR (SRK model)
