Development and start up of a co-injection system of coal tar/natural gas in blast furnace no. 4; Desarrollo y puesta en operacion de un sistema de co-inyeccion de alquitran/gas natural en el alto horno no. 4

Abstract

The crisis has attracted the world`s attention on the need for energy conservation and the development in a greater extent the utilization of carbon base fuels and other energy sources (nuclear energy). Being a blast furnace, not only an energy consumer but also an energy producer, the greatest contribution to the pig iron cost is the energy needed to melt and reduce to metallic state the iron ores, this energy is mainly derived from coke. The dependence on coal via the coking plant to produce first fusion iron is incremented day after day as a result of the high levels of production. Altos Hornos de Mexico (AHMSA), contemplated within its strategic plan, the reduction in the production of its coking plants derived from the natural aging of its furnaces, consequently the shortage of coke for productions higher than 2.6 MMT of pig iron is pending. The injection of fuels into a blast furnace through its nozzles is a technology used for the diminishing the coke consumption of coke, its use implies a change in the philosophy of the blast furnace operation, and is currently employed in most of the blast furnaces of the world.

Being a blast furnace, not only an energy consumer but also an energy producer, the greatest contribution to the pig iron cost is the energy needed to melt and reduce to metallic state the iron ores, this energy is mainly derived from coke. The dependence on coal via the coking plant to produce first fusion iron is incremented day after day as a result of the high levels of production. Altos Hornos de Mexico (AHMSA), contemplated within its strategic plan, the reduction in the production of its coking plants derived from the natural aging of its furnaces, consequently the shortage of coke for productions higher than 2.6 MMT of pig iron is pending. The injection of fuels into a blast furnace through its nozzles is a technology used for the diminishing the coke consumption of coke, its use implies a change in the philosophy of the blast furnace operation, and is currently employed in most of the blast furnaces of the world. AHMSA taking advantage of coal tar production (approx. 130 tons/day) in its coking plants decided the design and put into operation a co-injection system of coal tar and natural gas. The activities tending to carry out this project were initiated on April 1993, performing all of them with its own resources, completing them on July 18, 1993, day on which the injection of coal tar/natural gas in blast furnace No. 4 in a stable form. To date (October 1993), the coal tar injection has been increased up to 36 kg/ton of pig iron. During the injection periods, the presence of operational, mechanical and instrumentation problems have not been an obstacle for the evolution on the injection, fulfilling its function of substituting coke in a replacing relationship of 1:1, i.e. 1 kg of coal tar per each kg of coke, without affecting the product quality. [Espanol] La crisis de energia ha acaparado la atencion mundial sobre la necesidad de conservar la energia y desarrollar en un mayor grado el uso de combustibles en base a carbon y otras fuentes de energia (energia nuclear). Siendo el alto horno no solo un consumidor de energia sino tambien un generador de la misma (gas alto horno), la mayor contribucion al costo de arrabio es la energia necesaria para fundir y reducir al estado metalico los minerales de fierro, dicha energia en su mayoria proviene del coque. La dependencia del carbon via planta de coque para producir hierro de primera funcion se incrementa cada dia como resultado de los altos niveles de produccion. Altos Hornos de Mexico (AHMSA), contemplo dentro de su plan estrategico la disminucion de produccion de sus plantas coquizadoras derivada del envejecimiento natural de sus hornos, consecuencia de esto se hace inminente el deficit de coque para producciones superiores a 2.6 MMt de arrabio. La inyeccion de combustibles al alto horno a traves de sus toberas es una tecnologia para disminuir el consumo de coque, su uso implica un cambio en la filosofia de operacion del alto horno y es actualmente utilizada por la mayoria de los altos hornos del mundo. AHMSA aprovechando la generacion de alquitran (aprox. 130 ton/dia) de sus plantas coquizadoras decide disenar y poner en operacion un sistema de co-inyeccion de alquitran y gas natural, las actividades encaminadas a realizar lo anterior dieron inicio el mes de abril de 1993 efectuandose todas ellas con recursos propios de la empresa, finalizando el dia 18 de julio de 1993 dia en el cual se inicio la co-inyeccion de alquitran/gas natural en el Alto Horno no. 4 en forma estable. A la fecha (octubre 1993), la inyeccion de alquitran se ha incrementado hasta 36 kg/t. de arrabio, durante los periodos de inyeccion, la presencia de problemas operativos, mecanicos y de instrumentacion no han sido obstaculo para la evolucion de la inyeccion cumpliendo su funcion de sustituir al coque en una relacion de reemplazo de 1:1, es decir, 1 kg de alquitran por cada kg de coque sin afectar la calidad del producto.}
