| contents | Volatile matter release and thin and thick char formation as a function of vitrinite content, coal rank, time and temperature devolatilization Andrés Felipe Rojas-González Juan Barraza Ingeniería Thin thick walled char empirical models volatiles liberation Pulverized coal combustion is determined by char chemical reactivity, which depends of its morphology developed during the devolatilization process. In this work, some empirical relationships were obtained, in order to determine the composition of thin and thick walled char, as well as volatiles liberation, as a function of process variables (temperature and time devolatilization) and coal properties (vitrinite content and vitrinite reflectance). Those empirical models can be used to improve the combustion modelling and to simulate the char chemical reactivity. It was found that the empirical models, to predict different char morphology, gave a good approximation from coal properties and characteristic parameters of the devolatilization process, involving coal rank. 2013 artículo científico 0123-3033 https://www.redalyc.org/articulo.oa?id=291329166015 en http://www.redalyc.org/revista.oa?id=2913 Ingeniería y Competitividad application/pdf Universidad del Valle Ingeniería y Competitividad (Colombia) Num.2 Vol.15 |
