Abstract
Un reactor de lecho fluidizado, que incluye en su parte inferior una sección de horno que presenta un lecho de partículas sólidas fluidizadas, estando la sección del horno delimitada por paredes laterales, tales como las paredes laterales externas (22, 24) y / o las paredes de partición (34, 36), y una grilla inferior (28'', 28'''') y un dispositivo de suministro para introducir un gas, p. ejemplo, aire secundario, en la sección del horno en un nivel situado por encima de la grilla del fondo; incluyendo el dispositivo de suministro una cámara de fuente gaseosa (38''''), una abertura (48) en al menos una de las paredes laterales, situada en un nivel por encima de la grilla del fondo, y un conducto (42, 44) que presenta un primer extremo conectado a la abertura y un segundo extremo (52) conectado a la cámara de fuente gaseosa. El conducto incluye un sello de flujo sólido que impide que las partículas sólidas fluyan hacia atrás desde la sección del horno hacia el conducto, de forma que impidan o disminuyan notablemente la introducción del gas desde la cámara de fuente gaseosa hacia la sección del horno.
