The heat transfer rate is known; selection parameters for floating-head heat exchangers are urgently needed! ! ! Needed for the graduation project! ! Please! !
Thread Content
Hello everyone, I need to select a floating-head heat exchanger for my graduation project. There is no need to design the heat exchanger; it is sufficient to know some of its parameters. The heat transfer capacity of the heat exchanger has been calculated to be 3.54×10^7 kJ/h. I searched online for some parameters related to heat exchangers, but they all refer to the dimensions of their internal structure, which I don’t understand. . Then the two most important things I need to know are the diameters of the components for the inlet and outlet of the hot and cold fluids in the heat exchanger! ! This way I can choose the matching pipe diameter. . This is what I need. . Thank you all! ! ! Thank you! ! ! Please! ! ! This problem has been bothering me for a long time! ! ! It would be great if you could provide the specific model and parameters! ! ! First of all, thank you to all the guys and girls here! ! !
The diameter of the components at the inlet and outlet for the hot and cold fluids in the heat exchanger is determined based on the fluid flow rate and the designed flow velocity
Aren’t the inlet and outlet diameters of the hot and cold fluids in a heat exchanger included among the model parameters of the heat exchanger? Do I still have to calculate it myself?
Yes, the inlet and outlet diameters can be calculated based on the volumetric flow rate and the design flow velocity
Oh, thank you so much for that. What I’m a bit confused about is whether it’s possible to select the model directly based on the heat transfer amount When all the parameters of the fluid are known.
My flue gas flow rate is 130,000 Nm3/h, and the flow velocity in the flue gas ducts is 21 m/s. These process conditions also indicate that the diameter of the ducts is 2200×6 mm. Can such ducts be connected directly to the heat exchanger?
