(FR) BRULEUR A GAZ A MULTIPLES COURONNES DE FLAMMES CONCENTRIQUES
Abstract: front page image
(EN)The invention concerns a gas burner (1) with multiple concentric flame rings, comprising: a central burner (2) with a central ring of flame orifices (5), an axial central gas injector (6) and convergent-divergent means (7) forming venturi; and an annular outer burner (3) coaxially surrounding the central burner and provided with at least one annular ring of flame orifices (9), gas injecting means (10) and convergent-divergent means (12) forming venturis; the gas injecting means (10) include several radial gas injectors (11) around the central injector (6); the convergent-divergent means (12) include several radial convergent-divergent conduits (13) forming tubular venturis coaxial respectively to the radial injectors (11) and emerging in the annular outer burner.
(FR)Brûleur à gaz (1) à multiples couronnes de flammes concentriques, comprenant : un brûleur central (2) avec une couronne centrale d'orifices de flammes (5), un injecteur de gaz central (6) axial et des moyens convergents -divergents (7) formant venturi; et un brûleur extérieur annulaire (3) entourant coaxialement le brûleur central et muni d'au moins une couronne annulaire d'orifices de flammes (9), des moyens d'injection de gaz (10) et des moyens convergents-divergents (12) formant venturis; les moyens d'injection de gaz (10) comprennent plusieurs injecteurs de gaz (11) radiaux autour de 1' injecteur central (6); les moyens convergent s -divergent s (12) comprennent plusieurs conduits convergents-divergents (13) radiaux formant venturis tubulaires coaxiaux respectivement aux injecteurs radiaux (11) et débouchant dans le brûleur extérieur annulaire.
