High-pressure gas exchanges heat with cooling water, with water entering from the top and exiting from the bottom
Thread Content
The company has a shell-and-tube heat exchanger; the heat transfer medium is nitrogen at 5 MPa, which exchanges heat with circulating water. The gas flows through the tube side while the water flows through the shell side, with water entering from the top and exiting from the bottom. Why is that? Wouldn’t it be better if water entered from the bottom and exited from the top?
This should be determined based on actual needs and the internal structure; if there are any issues during installation on-site, it is best to check whether the installation diagrams match.
Let’s take a look at the drawings first, at the structure of the heat exchanger
Will flow rate or silt accumulation be taken into consideration, with inflow at the top and outflow at the bottom?
