Abstract

ESTA INVENCION DESCRIBE UN METODO PARA REDUCIR LA EMISION DE NO SUB X EN PROCESO DE COMBUSTION EN UN LECHO FLUIDIFICADO A PRESION (11) CON ABSORBENTE AÑADIDO, POR EJEMPLO PIEDRA CALIZA O DOLOMITA. AMONIACO U OTRAS SUSTANCIAS CONTENIENDO NITROGENO O UNA SUSTANCIA QUE PRODUCE AMONIACO O NITROGENO SE INYECTA EN EL GAS DE ESCAPE PARA ENTRAR EN REACCION CON LOS COMPONENTES DEL GAS DE ESCAPE EN UNA ZONA INICIAL (23) COMPRENDIENDO UN ESPACIO LIBRE EN EL QUE SE MANTIENEN EL GAS DE ESCAPE Y PARTICULAS DE POLVO ALLI SUSPENDIDAS, Y DESPUES EN UNA SEGUNDA ZONA (20) EN LA QUE EL AMONIACO ES PUESTO EN CONTACTO CON UNA SUPERFICIE SOLIDA ALCANZADA POR LA CONCENTRACION DE LAS PARTICULAS DE POLVO.
