Abstract

PROCEDIMIENTO DE REDUCCION DE LOS OXIDOS DE NITROGENO CONTENIDOS EN LOS HUMOS PROCEDENTES DE UNA COMBUSTION PRIMARIA (A), EN UN HORNO, POR RECOMBUSTION. SE REFIERE TAMBIEN A UNA INSTALACION PARA LA PUESTA EN PRACTICA DE ESTE PROCEDIMIENTO. EL PROCEDIMIENTO SEGUN LA INVENCION SE CARACTERIZA PORQUE SE INYECTA UN COMBUSTIBLE SECUNDARIO EN LA ZONA DE RECOMBUSTION (B) DE DICHO HORNO, SEGUN AL MENOS DOS CHORROS (2,2'') ASOCIADOS A PRESION RELATIVAMENTE ALTA Y RELATIVAMENTE BAJA, RESPECTIVAMENTE. LA INVENCION ENCUENTRA SU APLICACION EN EL CAMPO DE LA DEPURACION DE LOS HUMOS, PROCEDENTES DE UNA COMBUSTION PRIMARIA.PROCEDURE FOR REDUCTION OF NITROGEN OXIDES CONTAINED IN FUMES FROM A PRIMARY COMBUSTION (A), IN AN OVEN, BY RECOMBUSTION. IT ALSO REFERS TO AN INSTALLATION FOR THE PUTTING INTO PRACTICE OF THIS PROCEDURE. THE PROCEDURE ACCORDING TO THE INVENTION IS CHARACTERIZED BECAUSE A SECONDARY FUEL IS INJECTED IN THE SUCH OVEN RECOMBUSTION ZONE (B), ACCORDING TO THE LEAST TWO JETS (2.2 '') ASSOCIATED WITH RELATIVELY HIGH AND RELATIVELY LOW PRESSURE. THE INVENTION FINDS ITS APPLICATION IN THE FIELD OF SMOKE DEPURATION, COMING FROM A PRIMARY COMBUSTION.
