Abstract

Es descubierto un proceso que incrementa la salida de un sistema de combustión con quemado de carbón de alto contenido de hierro y/o calcio, reduciendo la tendencia de formación de escoria en la superficie de los intercambiadores de calor y cambiando la naturaleza de la escoria para hacer más fácil su eliminación. El proceso incluye la combustión del carbón formador de escoria de alto contenido de hierro y/o calcio con un exceso total de oxígeno; movilizando los gases resultantes de la combustión por equipo de intercambio de calor bajo condiciones que causen enfriamiento de la escoria formada por el quemado del combustible y, previo al contacto con el equipo de intercambio de calor, introduciendo trihidróxido de aluminio acuoso en cantidades, tamaño de gota y concentraciones efectivas para reducir el nivel de ensuciamiento y, preferentemente, aumentando la friabilidad de la escoria resultante.De preferencia, el trihidróxido de aluminio se introduce en forma de líquido acuoso empleando Dinámica de Fluidos Computarizada para determinar la velocidad de flujo y seleccionar la velocidad y fuerza de introducción, sitio(s), concentración y tamaño de gota. Preferentemente, la velocidad de alimentación será mayor de 2.724 kg (6 libras) de trihidróxido de aluminio por tonelada y a 0.908 kg (2 libras) ...A process is discovered that increases the output of a combustion system with burnt coal of high iron and / or calcium content, reducing the tendency of slag formation on the surface of heat exchangers and changing the nature of the slag to make its removal easier. The process includes the combustion of the slag-forming coal of high iron and / or calcium content with a total excess of oxygen; mobilizing the gases resulting from combustion by heat exchange equipment under conditions that cause slag cooling formed by the burning of the fuel and, prior to contact with the heat exchange equipment, introducing aqueous aluminum trihydroxide in quantities, size of drop and effective concentrations to reduce the level of fouling and, preferably, increasing the friability of the resulting slag. Preferably, the aluminum trihydroxide is introduced as an aqueous liquid using Computerized Fluid Dynamics to determine the flow rate and select the speed and force of introduction, site (s), concentration and drop size. Preferably, the feed rate will be greater than 2,724 kg (6 pounds) of aluminum trihydroxide per ton and at 0.908 kg (2 pounds) ...
