Abstract

Una caldera para lecho fluidizado circulante (CFB, circulating fluidized bed) incluye una cámara de reaccion, en la que un lecho fluidizado burbujeante (BFB, bubbling fluidized bed) se halla contenido dentro un cerramiento dentro de la porcion inferior de la cámara de reaccion y contiene un intercambiador de calor controlable situado dentro del lecho (IBHX, controllable in-bed heat exchanger) que ocupa parte del piso de la cámara de reaccion. Una pluralidad de boquillas de aire secundario situadas dentro del lecho comprende una pluralidad de tubos que están agrupados entre sí y que se extienden a través del ancho de la pared de cerramiento del BFB y de una pared externa del CFB. Las boquillas están posicionadas para impedir la deflexion por los chorros de aire secundario, de los solidos que caen sobre el BFB desde el CFB, evitándose al mismo tiempo una estructura complicada que interferiría con los movimientos de gases y/o solidos dentro del horno. Las aberturas de salida de la/boquillas están a ras, o casi a ras, con la pared de cerramiento del BFB.
