Abstract

PROCEDIMIENTO PARA EL CONTROL DE LA TEMPERATURA DEL AIRE EN UNA INSTALACION DE INYECCION DE COMBUSTIBLE SOLIDO EN UN ALTO HORNO. CONSISTENTE, BASICAMENTE, EN MEZCLAR EL AIRE CALIENTE PROVENIENTE DE LOS COWPERS (12, 14) CON UNA CANTIDAD DOSIFICABLE DE AIRE FRIO, DE FORMA QUE LA TEMPRATURA DE LA MEZCLA SEA UNIFORME. LA CANTIDAD DE AIRE FRIO NECESARIA ES FIJADA POR UNA VALVULA (20) QUE SE REGULA AUTOMATICAMENTE EN FUNCION DE LA TEMPERATURA DEL AIRE EN LA ENTRADA AL HORNO. PARTE DEL AIRE FRIO ADMITIDO POR LA VALVULA DE CONTROL (20) ES DESTINADO A LA INYECCION DE COMBUSTIBLE, PARA LO QUE SUFRE UNA COMPRESION Y POSTERIOR ENFRIAMIENTO QUE PERMITE SITUAR SU TEMPERATURA POR DEBAJO DE LA DE AUTOENCENDIDO.
