A system and apparatus is disclosed for delivering fuel to a furnace using an inert gas medium which has acquired moisture from the application of the furnace stack gas for drying the incoming fuel material during the reduction of the fuel to a desired size for combustion in the furnace. The use of an oxygen deficient inert gases medium as a propellant to deliver the fuel to the furnace is augmented by supplying air to the furnace to establish a staged combustion environment in the furnace to avoid the generation of high levels of the pollutant nitrous oxide which is understood to be generated by high flame temperatures and with high oxygen and nitrogen concentrations.
éseau et appareillage destinés à alimenter en combustible un appareil de chauffage au moyen d'un gaz inerte devenu humide par séchage du combustible au contact des gaz de cheminée, le volume du combustible étant réduit à la dimension voulue pour la combustion dans l'appareil de chauffage. L'utilisation de gaz inertes à faible teneur en oxygène comme agent propulseur pour alimenter en combustible l'appareil de chauffage est complétée par une alimentation en air de l'appareil de chauffage afin de réaliser une combustion étagée et éviter la production de hauts niveaux d'oxydes d'azote polluants qui sont, on le sait, générés par les températures élevées de la flamme et ce, à de fortes concentrations d'oxygène et d'azote.
