Abstract
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.
