Simulation confirms literature data regarding the higher yield of light fractions (density ρ ⩽ 1.28–1.30 g/cm3) from reduced coal than from slightly reduced coal. The predominance of light fractions with an elevated hydrogen content in the coal’s organic mass facilitates the formation of...
Statistical analysis of a representative database reveals the relation of the vitrinite reflection coefficient, the yield of volatiles, and the heat of combustion of solid fuels to the structural parameters of the organic component. This relationship is of great practical interest.
The results for the clinkering properties obtained on the basis of State Standard GOST 9318-91 (ISO 335-74) and the ISO 15585 standard are compared.
The influence of the following factors on the reactivity CRI and hot strength CSR in industrial coking is studied: eliminating bituminous coal from the coal batch; considerably increasing the coking periods; and significantly reducing the ash content of the batch. Batch composition such that the...
Two sets of experimental data characterizing the chemical composition of coal ash, its flow temperature t
c, and the CSR and CRI values of the coke from such coal are analyzed. The results indicate that the content of four oxides (SiO2, Fe2O3, CaO, and Na2O) may be used to predict t
c and also...
A patented system for stabilizing coke properties and sorting the coke flux into two size classes is described. Formulas are presented for the inclination of the system such that the actual value of a physicomechanical property is adjusted to the desired value. Sample calculations are outlined....
Analysis of literature data (including ASTM standards) shows that the only existing method that permits the identification of meso phase in pitch is optical microscopy. Even in special conditions conducive to meso-phase development, its formation in the pitch considered is found to be extremely...
Operational experience with the automatic control system for the desulfurization of coke-oven gas at OAO Magnitogorskii Metallurgicheskii Kombinat is considered. This system was designed by Krupp-Koppers. Problems with the control system are analyzed—in particular, problems typical of control...
