Title (EN) APPARATUS FOR GAS GENERATION
(FR) APPAREIL POUR LA PRODUCTION DE GAZ
Abstract:
(EN) An electrolytic gas generating apparatus for producing a combustible mixture of hydrogen and oxygen by electrolysis of water is disclosed, for particular use in a gas welding apparatus. The generating apparatus comprises a d.c. power supply (100) connected to electrolytic cells (200), a dehumidifier (400) for scrubbing the gas mixture generated by the cells (200), a gas regulator (500), a modifier (600) which modifies the combustion characteristics of the gas and a flash arrester (660). Gas generation is controlled by a main control board (800) in accordance with sensors which measure parameters to calculate indirectly the gas flowrate and control this in accordance with demand.
(FR) Appareil pour la production de gaz électrolytique, destiné à produire un mélange combustible d'hydrogène et d'oxygène par électrolyse de l'eau et s'utilisant notamment dans un appareil de soudage au gaz. L'appareil de production comprend une alimentation électrique c.c. (100) reliée à des cellules électrolytiques (200), un déshydrateur (400) pour épurer le mélange de gaz produit par les cellules (200), un régulateur de gaz (500), un modificateur (600) qui modifie les caractéristiques de combustion du gaz, ainsi qu'un pare-flamme (660). La production de gaz est commandée par un pupitre de commande principal (800) en fonction de capteurs qui mesurent des paramètres pour calculer indirectement le débit de gaz et le réguler à la demande.
