Heat transfer coefficient of shell-and-tube heat exchangers
Thread Content
The heat transfer medium in the shell-and-tube heat exchanger is heat transfer oil, while the cold medium is natural gas. What is the approximate heat transfer coefficient? Please ask the bosses for help, thank you.
Because the cold side is a gas, the heat transfer coefficient won’t be high; it’s probably between 30 and 100
If the heat medium is a gas, will the heat transfer coefficient be higher?
What if the cold side is water and the hot side is steam turning into condensed water?
Non-condensable gases result in poor heat transfer, whether on the tube side or the shell side； For condensable gases, due to the phase change process that occurs, heat transfer is very good, but relatively speaking, the fouling thermal resistance has a greater impact.
