Abstract (en)
[origin: WO2013021366A2] A double inlet centrifugal fan (1), in particular for the evacuation of combustion fumes in thermal power plants, producing less mechanical vibrations and lower noise levels, thanks to the presence of an anti-vortex fin (14) at the fan outlet section (4) extending on a lying plane parallel to the fluid flow direction (F).
