Abstract
[ES] La modelización de distintos problemas físicos, por ejemplo la combustión, es uno de
los objetivos de la matemática aplicada. El modelo BFL explica la combustión de carbón
pulverizado dentro de la caldera de una Central Térmica cuya finalidad es transformar
agua en estado líquido a estado gaseoso para poder generar energía eléctrica al mover un
alternador.
La aportación realizada en este trabajo es la resolución mediante distintos métodos
numéricos del modelo mencionado anteriormente. Concretamente, nos centraremos en la
resolución del sistema de DAE’s que modela la gasificación del carbono fijo contenido en
la partícula de carbón.
En cuanto a la organización de este trabajo se distinguen dos bloques: el primero de ellos
donde se explican de manera teórica el modelo y los métodos numéricos utilizados, mientras
que en el segundo se exponen los resultados obtenidos mediante los códigos implementados
y las conclusiones.

The BFL model explains the combustion of pulverized coal inside the boiler of a thermal power plant whose purpose is to transform liquid water into water vapor in order to generate electric power. The contribution made in this work is the resolution by different numerical methods of the aforementioned model. Specifically, we will focus on the resolution of the DAE’s system that models the gasification of the char contained in the coal particle. As regards the organization of this work, two blocks are distinguished: the first one, where the model and the numerical methods used are theoretically explained, while the second one exposes the results obtained through the codes implemented and the conclusions.
