Abstract

LA CANTIDAD DE N2O PRESENTE EN LOS GASES DE LA COMBUSTION DESCARGADOS DE UN SISTEMA DE COMBUSTION DE LECHO FLUIDIFICADO SE MINIMIZA MEZCLANDO DE FORMA ENERGICA E INTIMA LOS GASES DE LA COMBUSTION (CON PARTICULAS ARRASTRADAS) DEL LECHO FLUIDIFICADO A BASE DE AUMENTAR LA VELOCIDAD DE LOS GASES DE LA COMBUSTION Y DE REDUCIR DESPUES LA VELOCIDAD A PARTIR DEL NIVEL AUMENTADO, INTRODUCIENDO UN CATALIZADOR DE DESCOMPOSICION DE N2O EN LOS GASES DE LA COMBUSTION Y PARTICULAS JUSTO DESPUES DE AUMENTAR Y REDUCIR LA VELOCIDAD Y MEZCLANDO EL CATALIZADOR DE N2O CON LOS GASES DE LA COMBUSTION Y LAS PARTICULAS PARA QUE TENGA LUGAR LA DESCOMPOSICION DEL N2O. EL CATALIZADOR ES UN SORBENTE BASADO EN CALCIO, TAL COMO CAO O CALIZA, SI BIEN SE PUEDEN UTILIZAR TAMBIEN NIO Y OTROS CATALIZADORES. NORMALMENTE LA DESCOMPOSICION TIENE LUGAR SIN QUE AUMENTE LA TEMPERATURA DE LOS GASES DE LA COMBUSTION. EL AUMENTO DE LA VELOCIDAD SE CONSIGUE APLICANDO UNA CONSTRICCION EN LA CAMARA DE COMBUSTION.
