Abstract

EN EL CONDUCTO DE GAS DE COMBUSTION DE UNA CENTRAL DE POTENCIA, ES HABITUAL LA ALIMENTACION DE AMONIACO DE FORMA NECESARIA PARA LA DESCOMPOSICION CATALITICA DE OXIDOS DE NITROGENO DENTRO DE LOS GASES DE COMBUSTION A TRAVES DE UNA MULTIPLICIDAD DE CONDUCCIONES DE ALIMENTACION Y TOBERAS, Y A TRAVES DEL MISMO NUMERO DE VALVULAS A SER AJUSTADAS, DE TAL MODO QUE EL AMONIACO ES DISTRIBUIDO DE MANERA HOMOGENEA A TRAVES DEL GAS DE COMBUSTION. LA CAIDA DE PRESION PRODUCIDA POR ESTE EQUIPAMIENTO EN LA CONDUCCION DE GAS DE COMBUSTION ES RELATIVAMENTE ALTA, Y CON ELLO EL EQUIPAMIENTO EN SI MISMO ES RELATIVAMENTE COMPLEJO Y COSTOSO. PARA SUPERAR ESTAS DESVENTAJAS, LA INVENCION PROPONE UNA INSTALACION (14,36) DE MEZCLA Y ALIMENTACION COMBINADA, DISEÑADA PARA ALIMENTAR UN PRIMER MEDIO (M1) FLUIDO, POR EJEMPLO AMONIACO, DENTRO DE UN SEGUNDO MEDIO (M2) FLUIDO, POR EJEMPLO GASES (28) DE COMBUSTION CONTENIENDO OXIDOS DE NITROGENO, TRANSPORTADOS POR MEDIO DE UNA CONDUCCION (4) Y SIENDO CONDUCIDOS A LA MEZCLA DE DOS MEDIOS (M1, M2) FLUIDOS. LA INSTALACION INCLUYE AL MENOS UNA CONDUCCION QUE TRANSPORTA EL PRIMER MEDIO (M1) FLUIDO, CON AL MENOS UNA PUERTA (22) DE ALIMENTACION, Y UNA UNIDAD (26,26A A 26H) DE MEZCLA. DE FORMA RELATIVA CON RESPECTO AL AREA (A) DE SECCION TRANSVERSAL Y AL DIAMETRO HIDRAULICO D{SUB,DYDR} DE LA CONDUCCION (4), LA INSTALACION DISPONE DE ALIMENTACION DESDE 0,05 HASTA 10 ABERTURAS (22) DE ALIMENTACION Y LA UNIDAD (26,26A A 26H) DE ALIMENTACION SE ENCUENTRA ENTRE 0,05 Y TRES VECES D{SUB,HYDR}. ESTO ASEGURA QUE EL AMONIACO ES GUIADO Y MEZCLADO CON EL GAS DE COMBUSTION DE FORMA HOMOGENEA (FIG.2).
