Abstract

UN METODO PARA POTENCIAR LA MINIMIZACION DEL CONTROL DE NOx EN UN GENERADOR (12) DE VAPOR DE LECHO FLUIDO CIRCULANTE EN EL QUE SE INYECTA COMBUSTIBLE, AIRE FLUIDIFICANTE, UN NIVEL INFERIOR DE AIRE DE COMBUSTION Y UN NIVEL SUPERIOR DE AIRE DE COMBUSTION. EL COMBUSTIBLE SE INYECTA EN UNA PRIMERA LOCALIZACION (30), EL AIRE FLUIDIFICANTE SE INYECTA EN UNA SEGUNDA LOCALIZACION (24), EL NIVEL INFERIOR DEL AIRE DE COMBUSTION SE INYECTA EN UNA TERCERA LOCALIZACION (50B) Y EL NIVEL SUPERIOR DE AIRE DE COMBUSTION SE INYECTA EN UNA CUARTA LOCALIZACION (50A). CON OBJETO DE POTENCIAR LA MINIMIZACION DEL CONTROL DE NOx DENTRO DE UN GENERADOR (12) DE VAPOR DE LECHO FLUIDO CIRCULANTE, EL NIVEL INFERIOR DE AIRE DE COMBUSTION (50B), ASI COMO EL NIVEL SUPERIOR DE AIRE DE COMBUSTION (50A) ESTAN AMBOS DESPLAZADOS EN UN PLANO HORIZONTAL ASI COMO EN UN PLANO VERTICAL PARA DE DICHA MANERA CONTROLAR EL FLUJO (50B) DEL AIRE DE COMBUSTION DEL NIVEL INFERIOR Y EL FLUJO (50A) DEL AIRE DE COMBUSTION DEL NIVEL SUPERIOR,DE FORMA QUE LA ESTEQUIOMETRIA LOCAL DENTRO DEL GENERADOR (12) DE VAPOR DE LECHO FLUIDO CIRCULANTE SE MANTIENE EN UN INTERVALO COMPRENDIDO ENTRE UNA ESTEQUIOMETRIA DEL 70 % AL 90 %.
