Integrated air foil and diamond flow vane

Abstract

A flow enhancing arrangement for ducts such as rectangular flue ducts wherein a series of tear shaped foils are spacedly mounted in the duct extending from top to bottom thereof and where a series of diamond shaped vanes also extending from the top to the bottom of the duct are spacedly mounted between the tear shaped foils to provide a more uniform flow distribution and to lower the pressure thereby. A series of baffles extending from both the tear shaped foils and the diamond shaped vanes may also be used.

1 . A flow enhancing arrangement for ducts having fluid flow therein comprising: 
 a series of tear-shaped foils spacedly extending across the duct; and    a series of diamond shaped vanes shapedly extending between said series of tear-shaped foils.    
     
     
         2 . A flow enhancing arrangement for ducts as set forth in  claim 1  including a series of baffles extending from said tear shaped foils and from said diamond shaped vanes.  
     
     
         3 . A flow enhancing and arrangement for ducts as set forth in  claim 2  wherein said tear-shaped foils have a rounded end and a sharp end and wherein said baffles extend from said rounded end of said foils.  
     
     
         4 . A flow enhancing arrangement for ducts as set forth in  claim 1  wherein said diamond shaped vanes have sharp front and back ends and said baffles extend from said front end.  
     
     
         5 . A flow enhancing arrangement for ducts as set forth in  claim 1  wherein said tear-shaped foils have a rounded end and a sharp end and wherein said baffles extend from said rounded end of said foils.  
     
     
         6 . A flow enhancing arrangement for ducts as set forth in  claim 5  wherein said diamond shaped vanes have sharp front and back ends.  
     
     
         7 . A flow enhancing arrangement for ducts as set forth in  claim 5  wherein the duct is a rectangular flue duct.
