Regarding the circulation rate of shell-and-tube heat exchangers
Thread Content
Hai Youhao: Our company has 6 shell-and-tube heat exchangers with a heat exchange area of 20 square meters. Their main function is to condense the vapor water from the reaction vessels; each heat exchanger is required to handle about 500 T/H of condensed water. What size would be appropriate for the main circulating water pipeline in Hai Youhao’s system? (The main pipe divides into 6 branches to feed 6 condensers), thank you!
Is this amount of water correct? Such a large amount
I made a mistake; it’s 500KG/H
Without detailed calculations, DN50 should be sufficient.
For 3 cubic volume, with a flow rate of 2 meters per second, select a pipe diameter of DN25 or larger.
Since it’s 1/6, and considering the diameter of the branch pipes, let’s choose DN50 for the main pipe
