文摘

Analysis of the chemical composition of solid fuel permits the identification of the optimal proportions of its components for effective heat generation. Kinetic analysis of the oxidation of the carbon in the coke, by means of the complete curve obtained in differential scanning calorimetry with continuous heating, reveals six basic periods: drying and heating; oxidation of the carbon in the coke; endothermal gasification; surface oxidation of the gaseous products; flame combustion of the gaseous products, and oxidation of interior layers of the fuel. By assessing the behavior of the coke in shaft furnaces, the requirements on its granulometric composition, density, and mechanical strength in transportation and heat treatment may be determined. Recommendations are made regarding the characteristics of coke for use in the basic forms of cupola furnaces.
