Abstract
EN UNA PLANTA DE HORNO PARA QUEMAR MATERIALES MINERALES EN BRUTO, POR EJEMPLO, MATERIALES DE CEMENTO EN BRUTO, POR MEDIO DE NITROGENO CONTENIENDO FUEL SOLIDO, POR EJEMPLO CARBON; DICHA PLANTA COMPRENDE UN HORNO (1), UN REFRIGERADOR DE MATERIALES (2) ACOPLADO DESPUES DEL HORNO Y UN PRECALENTADOR DE MULTIPLES ETAPAS Y MULTIPLES CADENAS (18-27 Y 18''-27'') MONTADO ANTES QUE EL HORNO. UNA CADENA, LA CADENA DEL HORNO (18-27), QUE ESTA EN CONEXION DIRECTA CON LA TUBERIA DE SUBIDA DEL HORNO (8) Y LA SEGUNDA CADENA, LA CADENA DE CALCINAMIENTO (18''-27'') QUE ESTA EN CONEXION CON UN CALCINADOR SEPARADO (4) HACIA EL CUAL SE DIRIJE EL AIRE EN COMBUSTION EN LA FORMA DE AIRE DE REFRIGERADOR UTILIZADO, A TRAVES DE UNA ENTRADA. EN LA TUBERIA DE SUBIDA DEL HORNO (8) SE ESTABLECE UNA ZONA DE REDUCCION DEL NOX Y UNA PARTE DE LA CADENA DEL HORNO DESDE UNA ENTRADA (13) PARA EL NITROGENO QUE CONTIENE FUEL SOLIDO DE UN CONDUCTO DE FUEL (10) Y UNA ENTRADA (12) DE UNA RAMIFICACION (14) PARA EL SUMINISTRO DE AIRE DE REFIGERADOR UTILIZADO. LA LONGITUD DE LA ZONA DE REDUCCION DE NOX, LA COMBUSTION EN LA ZONA DE CARBON SUMINISTRADO QUE CONTIENE FUEL PARA LA REACCION ENTRE LOS ATOMOS DE NITROGENO (N) Y EL OXIDO DE NITROGENO (NO) FORMADOS EN EL HORNO PARA CONSTITUIR EL NITROGENO NO DAÑINO (N2) Y LA SEPARACION DEL FUEL QUE NO HA ENTRADO EN COMBUSTION CON LOS MATERIALES EN BRUTO PARCIALMENTE CALCINADOS, DE LOS GASES DEL HUMO DEL HORNO EN LA ETAPA DEL CICLON (18) Y EL POSTERIOR TRATAMIENTO DE DICHOS PRODUCTOS EN EL CALCINADOR (4) DONDE LA COMBUSTION DEL FUEL SUMINISTRADO DESDE LA TUBERIA DE SUBIDA DEL HORNO QUE TIENE UN CONTENIDO DE NITROGENO REDUCIDO CAUSA UNA REDUCCION DE LA EMISION DE NOX DE LA CADENA DEL CALCINADOR (18''-27''), ASEGURAN UN ALTO GRADO DE REDUCCION DE LA EMISION DE NOX TOTAL DE LA PLANTA.
