Abstract

UN METODO DE COMBUSTION EN UN LECHO FLUIDIFICADO QUE UTILIZA UN MATERIAL DE CARGA SORBENTE FINO Y GRUESO PARA CONTROLAR LA TEMPERATURA DE UN FLUIDO DE REFRIGERACION COMO POR EJEMPLO AGUA O VAPOR QUE CIRCULA A TRAVES DE UN CIRCUITO DE CIRCULACION DE FLUIDOS DE UNA CAMARA DE COMBUSTION DE LECHO FLUIDIFICADO. LAS PARTICULAS COMBUSTIBLES, COMO POR EJEMPLO CARBON, JUNTO CON UN MATERIAL SORBENTE RELATIVAMENTE FINO Y RELATIVAMENTE GRUESO, COMO POR EJEMPLO PIEDRA CALIZA, SE ALIMENTAN EN LA SECCION DEL HORNO DE UN REACTOR DE LECHO FLUIDIFICADO. EL COMBUSTIBLE SE QUEMA Y SE INTRODUCE UN GAS FLUIDIFICADOR EN LA SECCION DEL HORNO. LOS GASES DE LA COMBUSTION Y EL MATERIAL ARRASTRADO PASAN DESDE LA SECCION DEL HORNO Y EL MATERIAL ARRASTRADO SE SEPARA DE LOS GASES DE LA COMBUSTION. EL MATERIAL ARRASTRADO SEPARADO PASA A UNA SECCION DE INTERCAMBIO DE CALOR DE RECICLADO Y SE ENFRIA ANTES DE QUE PASE A LA SECCION DEL HORNO. EN LA SECCION DE INTERCAMBIO DE CALOR DE RECICLADO SE COLOCAN UNAS SUPERFICIES DE INTERCAMBIO DE CALOR QUE FORMAN PARTE DE UN CIRCUITO DE CIRCULACION DE FLUIDOS PARA TRANSFERIR CALOR DESDE EL MATERIAL ARRASTRADO SEPARADO A UN FLUIDO REFRIGERANTE COMO POR EJEMPLO AGUA O VAPOR QUE SE ENCUENTRA CIRCULANDO A TRAVES DEL CIRCUITO. LA RELACION DE MATERIAL SORBENTE DE FINO A GRUESO SE CONTROLA PARA CONTROLAR LA TRASFERENCIA DE CALOR DESDE EL MATERIAL ARRASTRADO SEPARADO EN LA SECCION DE INTERCAMBIO DE CALOR DE RECICLADO AL FLUIDO REFRIGERANTE, CON LO QUE SE CONTROLA ASI LA TEMPERATURA DEL FLUIDO REFRIGERANTE Y SE PERMITE QUE LA TEMPERATURA DEL FLUIDO REFRIGERANTE SE MANTENGA CONSTANTE DURANTE UNA DIVERSIDAD DE CARGAS EN EL REACTOR DE LECHO FLUIDIFICADO.
