  • It is an object of the present invention, as a combusting and incinerating system which is invented to solve the above problems, to stably produce and continuously supply dry distilled gases from high quality wastes to a simple incinerating or industrial combusting facility so that the gases can be used as substitute fuels in the incinerating or industrial combusting facility, and to provide a system using substitute fuels of dry distilled gases of wastes comprising: a dry distilled gas generator producing dry distilled gases by continuously dry distilling high quality wastes; a transferring pipe with a control valve controlling the transfer amount of dry distilled gases, which directly transfers dry distilled gases produced in the dry distilled gas generator to an isolated combusting and incinerating facility; dry distilled pressurized gas transferring combustor comprising a gas-air mixing injector which combines gases from the transferring pipe with a combusted air pressure and injects the mixture of gas and combusted air into a combustor; a combusting burner for combusting

Abstract

L'invention porte sur un système de combustion/incinération utilisant du gaz distillé sec obtenu par distillation continue de déchets comme combustible de substitution dans différentes installations de combustion/incinération nécessitant une source de chaleur. Le système comporte plus particulièrement: un générateur de gaz distillé sec; un équipement de transfert/combustion transférant le gaz distillé sec vers une installation de combustion/incinération par une conduite de transfert et en réglant la quantité; une installation de combustion/incinération à laquelle est rattachée l'équipement de transfert/combustion et constituant une source de chaleur alimentée en gaz distillé sec comme combustible de substitution (ou complémentaire); et un gestionnaire automatique maintenant de manière stable la vitesse et la pression dans le générateur de gaz distillé sec en agissant sur une soupape d'admission d'air, et sur une soupape d'admission de gaz, etc. et en faisant varier la quantité d'air de combustion, c.-à-d. à la pression de l'éjecteur de mélange air/gaz de l'équipement de transfert/combustion. On peut ainsi améliorer les effets du recyclage des déchets réutilisables, et les économies de combustible en raison de diminution radicale de la consommation de combustible complémentaire dans les incinérateurs ou installations industrielles, tout en réduisant les effets, dus à la faible génération, des gaz nocifs tels que la dioxine etc. en raison d'une combustion peu coûteuse et à haute température de ces gaz secs distillés servant de combustible de substitution(complémentaire).
