Abstract

Un horno que tiene uno o más quemadores para proyectar corrientes de combustible dentro del horno caracterizado por un conducto que conduce a cada quemador y dimensionado para guiar combustible pulverizado al quemador en un volumen de aire portador mayor del deseado para la combustión eficaz en dicho quemador; por un concentrador en dicho conducto para separar una parte de dicho aire portador para reducir el contenido de aire de la corriente de combustible a un volumen destinado a la combustión eficiente en dicho quemador; por medios que conectan el concentrador con los quemadores para suministrarles combustible pulverizado arrastrado por el aire restante; por toberas situadas junto al quemador o quemadores para introducir corrientes de aire a alta velocidad en direcciones que induzcan un flujo de gases ardiendo junto a los chorros de combustible y mezcla de aire de dicho quemador o quemadores; por medios que conectan el concentrador con el horno en un lugar contiguo al quemador o quemadores y por toberas para suministrar al horno como aire secundario el volumen de aire en exceso separado de la corriente portadora de dicho concentrador.A furnace having one or more burners for projecting fuel streams into the furnace characterized by a conduit leading to each burner and sized to guide pulverized fuel to the burner in a volume of carrier air greater than that desired for effective combustion in said burner; by a concentrator in said conduit to separate a portion of said carrier air to reduce the air content of the fuel stream to a volume intended for efficient combustion in said burner; by means connecting the concentrator with the burners to supply them with pulverized fuel entrained by the remaining air; by nozzles located next to the burner or burners to introduce high speed air currents in directions that induce a flow of burning gases next to the fuel jets and air mixture of said burner or burners; by means connecting the concentrator with the furnace in a location adjacent to the burner or burners and by nozzles for supplying the furnace with the volume of excess air separated from the carrier stream of said concentrator as secondary air.
