Abstract

EL PROCEDIMIENTO PARA LA REDUCCION DE CONCENTRACION DE MONOXIDO DE NITROGENO EN UNA CORRIENTE DE GAS, PROCEDENTE DE UN PROCESO DE COMBUSTION , COMPRENDE LA INTRODUCCION DE PRODUCTOS QUIMICOS COMO, AMONIACO, SAL DE AMONIACO, UREA, CAL NITROGENADA EN LA CORRIENTE DE GASES. EN ESTA CORRIENTE SE GENERA ADICIONALMENTE UNA FUERTE TURBULENCIA DE FORMA QUE LA CORRIENTE DE GASES ES COMPRIMIDA ANTES DE LA ZONA DE TURBULENCIA. LA INTRODUCCION DE LOS PRODUCTOS DE TRATAMIENTO, SE REALIZA JUSTO ANTES DE LA ZONA DE TURBULENCIA Y LA CORRIENTE DE GAS, A CONTINUACION DE ESTA ZONA, DISMINUYE SU PRESION Y SE HACE MAS UNIFORME. PARA LA REALIZACION DE ESTE PROCEDIMIENTO, SE DISPONE DE UN HOGAR CON UNA PARRILLA (5) Y UNA ZONA DE TIRO HACIA ARRIBA (10) SEGUIDA DE OTRA ZONA DE TIRO DESCENDENTE (12). LA CORRIENTE DE GASES TRANSCURRE DESDE LA PARRILLA DEL HOGAR EN DIRECCION A LA ZONA DE TIRO ASCENDENTE (12), ESENCIALMENTE FORMANDO UNA "S". EL CAMBIO DE DIRECCION EN LA ZONA INFERIOR HACE QUE LA CORRIENTE SEA MAS SUAVEY LLEGUE A LA ZONA (11). EN LA ZONA SUPERIOR (16) DEL TIRO, LA CORRIENTE DE GASES SE COMPRIME A TRAVES DE UNA PENDIENTE Y EL CORRESPONDIENTE ESTRECHAMIENTO DE LA SECCION. LA TOBERA PULVERIZADORA (26) SE ENCUENTRA AL PRINCIPIO DE LA ZONA SUPERIOR (16) DEL TIRO ASCENDENTE Y ES ALLI DONDE LOS PRODUCTOS QUIMICOS SE INTRODUCEN. LA INTRODUCCION DE LOS PRODUCTOS QUIMICOS SE CONSIGUE POR LO TANTO JUSTO ANTES DE LA COMPRESION Y DE LA GENERACION DE FUERTE TURBULENCIA.
