Gas premix system adapted to feed a burner (Machine-translation by Google Translate, not legally binding)

Gas premix system adapted to feed a burner, in particular a condenser boiler burner, comprising a premix body (11) delimiting a premix chamber (12), including the premix chamber (12) an inlet (13) of an air/gas mixture, the premix chamber (12) being configured to feed the burner (9) with the air/gas mixture, and segmentation means (14; 14'; 14''; 14''') that segment the premix chamber (12) into at least a first sector (A) and a second sector (B), said first sector (A) being configured to feed a first zone (C) of the burner (9) and said second sector (B) being configured to feed a second zone (D) of the burner (9), the segmentation means (14; 14'; 14''; 14''') comprising means of closing (17; 17'; 17''; 17''') configured to prevent the passage of the air/gas mixture between both sectors (A, B) of the premix chamber (12), characterizes because the means of segmentation (14; 14'; 14''; 14''') comprise a segmenter (15) that delimits a closed contour inside the premix chamber (12), said closed contour being the second sector (B), surrounding the first sector (A) externally to the segmenter (15), including the segmenter (15) an opening (20) that communicates both sectors (A, B) of the premix chamber (12), closing the closing means (17; 17'; 17''; 17''') said opening (20) in a closed position, so that the gas/air mixture only reaches the first sector (A) in the closed position.
