<p>The mixer has an enclosure defining an air supply central duct and a fuel gas supply peripheral duct (16) that is arranged around the central duct. Multiple vanes (34) are extended transversally in the central duct, where the vanes are arranged in pairs. Each pair of vanes defines a gas intake channel that is extended from an annular opening (22) towards an interior of the central duct. The channel is formed in U-shape in a fluid flow direction, where a downstream side (38) of the channel is opened and the channel is closed on an upstream side (35) of the vane.</p> |
