INTEGRATED AIR FOIL AND DIAMOND FLOW VANE

摘要

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.
