Title
(EN) HIGH-TEMPERATURE GAS GENERATOR
(FR) GENERATEUR DE GAZ A HAUTE TEMPERATURE
Abstract
(EN)
A high-temperature gas generator capable of supplying an impurities-free high-temperature gas of around 700-1400 °C for a long period of time with minimum temperature variations, after a short preparing time. This gas generator includes heat accumulators (4, 5, 15, 16) capable of transmitting the sensible heat of a combustion gas to combustion air with a high efficiency by switching at a short cycle, and burners (2, 3) for burning with mainly a gas fuel supplied thereto, and forms a combustion apparatus adapted to supply combustion air or an arbitrary gas, which is to be heated to a high temperature, through the heat accumulators (4, 5) and discharge the combustion gas, to accumulate the heat in the heat accumulators (4, 5). After the temperature of the heat accumulators (4, 5) reaches a predetermined level, the combustion operation is interrupted, and the air or an arbitrary gas only is passed through the heat accumulators (4, 5), whereby an arbitrary gas heated to a predetermined level is supplied to the outside for a predetermined period of time.
(FR)
Générateur de gaz à haute température, capable de produire un gaz à haute température exempt d'impurétés dans une plage comprise entre 700° et 1400 °C environ pendant un laps de temps prolongé, moyennant des fluctuations de température minimales, après un temps de préparation court. Ce générateur comprend des accumulateurs de chaleur (4, 5, 15, 16) capable de transmettre la chaleur sensible d'un gaz de combustion à l'air de combustion sous un rendement élevé grâce à un échange en cycle court, et des brûleurs (2, 3) assurant la combustion avec un combustible gazeux. Il constitue un appareil de combustion adapté à une alimentation en air de combustion ou en un gaz d'arbitrage devant être porté à une température élévée par les accumulateurs de chaleur (4, 5) et à une libération du gaz de combustion tendant à une accumulation de la chaleur dans les accumulateurs de chaleurs (4, 5). Une fois que la température des accumulateurs de chaleur (4, 5) a atteint un niveau déterminé, l'opération de combustion est interrompue, et seul l'air ou le gaz d'arbitrage est admis dans les accumulateurs de chaleur (4, 5), après quoi le gaz d'arbitrage est, porté à une température déterminée, et libéré vers l'extérieur pendant un laps de temps déterminé.
