Abstract

Una disposición de válvula no mecánica para su uso con calderas de lecho fluidizado circulante (CFB) tiene una cámara de reacción de CFB y un lecho fluidizado burbujeante (BFB) dentro de un recinto en la porción inferior de la cámara de reacción de CFB, el BFB conteniendo un intercambiador de calor en lecho (IBHX). Los sólidos que fluyen desde el recinto de BFB hasta la cámara de reacción de CFB pueden controlarse utilizando una o más válvulas no mecánicas. Cada válvula no mecánica se controla independientemente utilizando medios de fluidización controlados independientemente. La válvula no mecánica tiene colectores para recolectar el contra-cernido de sólidos en los medios de fluidización de la válvula. Se eliminan los aglomerados que podrían bloquear la válvula. Las paredes de canal paralelas a la dirección del flujo de sólidos a través de la abertura de válvula pueden proporcionarse para reducir la interferencia externa con la fluidización local para mantener el funcionamiento adecuado de la válvula no mecánica.
