A spin vane for burners and over fire air ports in a furnace comprise a sheet-like vane element having a base and an extension extending perpendicularly off the base on the low pressure side of the vane element. The extension reduces the formation and propagation of vortices on the low pressure side of the vane, increasing flow efficiency and reducing pressure loss across the spin vanes.

Why it's free to use
- Filed February 19, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 19, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 19, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
