Abstract

METODO DE QUEMADO DE COMBUSTIBLE SOLIDO TENIENDO COMPOSICIONES ALCALINAS DE PUNTO DE FUSION BAJO, TALES COMO SALES DE METAL ALCALINO PARTICULARMENTE LIGNITO Y CARBON BITUMINOSO. EL COMBUSTIBLE ES INTRODUCIDO AL INTERIOR DE LA CAMARA DE REACCION DE UN REACTOR DE LECHO FLUIDIZADO CIRCULANTE, Y ES MEZCLADO CON ANTELACION A LA INTRODUCCION EN LA CAMARA DE REACCION CON UN MATERIAL REACTANTE, CAPAZ DE REACCIONAR CON LAS COMPOSICIONES ALCALINAS DE PUNTO DE FUSION BAJO DEL COMBUSTIBLE, PARA PRODUCIR COMPUESTOS DE METAL ALCALINO DURANTE LA COMBUSTION. LA TEMPERATURA EN LA CAMARA DE REACCION ES MANTENIDA POR DEBAJO DEL PUNTO DE FUSION DE LOS COMPUESTOS DE METAL ALCALINOS FORMADOS. EL MATERIAL REACTANTE COMPRENDE OXIDO DE SILICIO O UN OXIDO DE METAL, O HIDROXIDO, DEL GRUPO CONSTANTE DE ALUMINIO, CALCIO, MAGNESIO, HIERRO, TITANIO Y MEZCLAS DE DOS O MAS DE ELLOS. EL CAOLIN ES PARTICULARMENTE EFECTIVO, ESPECIALMENTE CUANDO LA RELACION MOLAR DE AL (NA Y K) ES AL MENOS 1.0.
