Abstract

EL INVENTO MUESTRA UN METODO DE SUMINISTRAR ABSORBENTE DE AZUFRE Y CARBON A UNA CAMARA DE COMBUSTION EN UN LECHO FLUIDIFICADO (6). SE TRITURA EL CARBON Y SE DIVIDE EN FRAGMENTOS MAS FINOS Y OTROS MAS BASTOS. LOS MAS FINOS SE MEZCLAN CON AGUA, POSIBLEMENTE CON ACEITE Y/O EMULSOR, FORMADO UNA PASTA QUE SE BOMBEA AL LECHO (16) DE LA CAMARA DE COMBUSTION (10) A TRAVES DE PRIMERAS TOBERAS (32). LA PARTE MAS BASTA SE INTRODUCE EN LA CAMARA DE COMBUSTION NEUMATICAMENTE EN ESTADO SECO, DIRECTAMENTE O A TRAVES DE UNO O MAS SISTEMAS DE TOLVA DE CIERRE (60) Y UNA SERIE DE OTRAS TOBERAS (36). EL INVENTO MUESTRA ASIMISMO UNA CENTRAL DE ENERGIA PARA LA APLICACION DE ESTE METODO.THE INVENTION SHOWS A METHOD OF PROVIDING ABSORBENT SULFUR AND COAL TO A COMBUSTION CHAMBER IN A FLUIDIFIED BED (6). THE COAL IS CRUSHED AND DIVIDED INTO FINE FRAGMENTS AND OTHER COARSE. THE FINEST ARE MIXED WITH WATER, POSSIBLY WITH OIL AND / OR EMULSOR, FORMING A PASTE THAT IS PUMPED TO THE BED (16) OF THE COMBUSTION CHAMBER (10) THROUGH FIRST NOZZLES (32). THE MOST ENOUGH PART IS INTRODUCED IN THE COMBUSTION CHAMBER PNEUMATICALLY IN THE DRY STATE, DIRECTLY OR THROUGH ONE OR MORE CLOSURE HOPPER SYSTEMS (60) AND A SERIES OF OTHER NOZZLES (36). THE INVENTION FURTHER SHOWS AN ENERGY CENTER FOR THE APPLICATION OF THIS METHOD.
