Abstract

BOQUILLA DE TOBERA PARA COMBUSTIBLE SOLIDO PULVERIZADO (12) MRFC (CONTROL DE LLAMA DE RECIRCULACION MINIMA) ESPECIALMENTE ADECUADA PARA FUNCIONAR EN COOPERACION CON UNA TOBERA DE COMBUSTIBLE SOLIDO (34) DE UN SISTEMA DE ENCENDIDO DEL TIPO QUE SE EMPLEA EN UN HORNO ENCENDIDO POR COMBUSTIBLE SOLIDO PULVERIZADO (10). LA BOQUILLA DE LA TOBERA PARA COMBUSTIBLE SOLIDO MRFC (12), CUANDO SE EMPLEA COMO TAL, FUNCIONA PARA MINIMIZAR LAS REGIONES DE VELOCIDAD BAJAS Y NEGATIVAS, ES DECIR LA RECIRCULACION, DE UN PLANO DE SALIDA DE LA BOQUILLA DE TOBERA DE COMBUSTIBLE SOLIDO MRFC (12) Y REDUCIR LA SUPERFICIE DE DEPOSITO DISPONIBLE SOBRE ESTA (12), Y VARIAR LAS CONDICIONES TERMICAS DE LA BOQUILLA DE LA TOBERA (12)/TOBERA DE COMBUSTIBLE SOLIDO (43) Y EVITAR QUE LA MATERIA "CALIENTE" DE PARTICULAS DE COMBUSTIBLE SOLIDO SE DEPOSITE SOBRE LA SUPERFICIE DE LA OBRA DE CHAPA METALICA DISPONIBLE DE LA BOQUILLA DE LA TOBERA DE COMBUSTIBLE SOLIDO MRFC (12). ESTA (12) INCLUYE UNA TUBERIA PARA EL AIRE DEL COMBUSTIBLE(46), UNA TUBERIA PRINCIPAL PARA EL AIRE (48) SITUADA DENTRO DE LA TUBERIA PARA EL AIRE DEL COMBUSTIBLE (46), UN SISTEMA DE SOPORTE DE LA TUBERIA PARA EL AIRE DEL COMBUSTIBLE (46) QUE FUNCIONA PARA SOPORTAR LA TUBERIA PRINCIPAL PARA EL AIRE (48) EN RELACION CON LA DEL AIRE DEL COMBUSTIBLE (46) Y UN SISTEMA DE PLACA SEPARADORA (52) SOSTENIDA DENTRO DE LA TUBERIA PRINCIPAL DEL AIRE.
