Which connection method is good for heat exchange with water vapor
Thread Content
Our factory has an unused horizontal heat exchanger that we plan to put to use for cooling and heat exchange of the boiler waste water. Should the boiler waste water flow in from the bottom and out from the top, or should it flow in from the top and out from the bottom?
It should work fine as long as the heat exchange is counterflow.
Generally, liquids flow in from below and out from above.:lol
Generally, it is from bottom to top, but this is not mandatory; as long as backflow is prevented, that’s sufficient
It is logical for hot water to enter from above and exit from below, as this ensures high heat exchange efficiency. To allow hot water to fill the housing, an exhaust port should be provided at the top of the housing.
Since it is hot water cooling, it is best to have flow from top to bottom in a counter-current manner.
Generally, the fluid that is being heated or evaporated should flow in from below and out from above. The condensed fluid generally flows in from above and out from below. No specific requirements are imposed on the cooled fluid. OP, your boiler’s drain water should be cooled, right? So I think it would be better to have flow from above to below.
The boiler discharge temperature is high, so it needs to be cooled. It’s not exactly water; it’s actually water vapor.
“\"Cool and exchange heat with the boiler waste water,\" preferably with water entering from above and exiting from below, with the main focus being on the removal of impurities from the cooler.
