Hi all,

 

I would like to ask you how to calculate a required length of pipe to cool airflow from a furnace from 700°C to 80°C. Airflow rate is 250l/min and the pipe will be made from Stainless Steel nominal pipe size 65mm.

 

Any help is more than welcome.

 

Thank you very much.

You should look for an air cooled heat exchanger. You can't use the pipe you describe. It is quite long and the pressure drop would be prohibitive. So, start with a new idea. Maybe a spray quench.

I would ask you to tell me how or why your thread was double-posted in our Forum.  I've taken the liberty of deleting your first post of the same topic since it was an identical duplicate of this, the second.

 

I am trying to stop what is a rash of multiple posts of the same topic in the same forum.  Perhaps there is something wrong with the posting set-up, and if so, we would want to remedy this flaw.  Multiple posts of the same topic cause a lot of problems with the forum and for our members, who are left in a quandary as to what post to respond to.  Archiving the threads also raises a complicated issue.

 

You can respond on my message service that you will find in my background page.

Thank you.
