Thermoacoustically Driven Pulse-Tube Refrigerator for Gas Turbines

08/23/2010 10:01 AM

This link shows how natural gas can be liquefied at 92K using thermoacoustics:

http://www.springerlink.com/content/h7662031801p8l83/fulltext.pdf

A portion of the NG is used to drive the hot reservoir, but works without moving mechanical parts.

.

Can this refrigeration method be used to condense out unwanted vapour from g-t inlet air in high humidity areas - driven by the turbine exhaust heat?

This is a long shot, but I knew a VP of Research at JBL Labs who was working on this concept under a contract with NASA. Seem's it might be a good way to cool lots of things. This was 20 years ago.

Harmon Industries is, or was, the parent company. They may have published something.

If this is something you would like to pursue, PM me and I'll give you his name.

Thanks for the offer, lynlynch.

As I'm not in a position to implement such a design I don't think it's appropriate to bother the guy you mention. I'm just intereted to know what other engineers think of using this tech on heat engines.

There's a local company in Troy,NY that makes this kind of stuff. They're called QDrive.
