A method and apparatus is provided for heating a reaction vessel for use in industrial applications. The apparatus includes a microwave generating device coupled to a waveguide having a means for causing multiple microwave propagation modes prior to directing the microwave into the reaction vessel. The waveguide is mounted to the reaction vessel and directs the microwave in an inclined-angular fashion, thereby generating a helical reflection pattern within the vessel's interior and providing a uniform heating of said interior. An isolation means is also provided, positioned between the microwave generating device and the reaction vessel, which incorporates a quartz window and a sealing means capable of compensating for any disparity in thermal expansion coefficients between the quartz and the material used to house the quartz.
Cette invention concerne une méthode et un appareil de chauffage d'une cuve à réaction industrielle. L'appareil comprend un générateur de micro-ondes raccordé à un guide d'ondes conçu pour créer des modes de propagation multiples avant de diriger les micro-ondes dans la cuve à réaction. Le guide d'ondes est raccordé à la cuve selon un angle incliné et injecte les micro-ondes dans la cuve selon cet angle, ce qui entraîne une réflexion des ondes en spirale à l'intérieur de la cuve et, par conséquent, une distribution uniforme de la chaleur. Un dispositif d'isolation intercalé entre le générateur de micro-ondes et cuve à réaction se compose d'une fenêtre en quartz et d'un joint d'étanchéité capable de compenser toute différence entre le coefficient de dilatation thermique du quartz et celui du matériau du cadre dans lequel est placé le quartz.
