The coal resources at OOO Metinvest Holding are considered, in a climate of increase requirements on coke quality and self-reliance. The parameters of high-quality coke are outlined, and the corresponding requirements on the coal batch employed are discussed. Recommendations regarding coal...
Methods of assessing coal oxidation are compared. The method developed by the Soviet Institute of Mining and the Coal Chemistry Institute is most expedient. On that basis, a draft of the Ukrainian DSTU standard on determining the oxidation of coal has been formulated. The method has been...
The preparation of blast-furnace coke in coke shop 1 at PAO Avdeevskii Koksokhimicheskii Zavod (AKKhZ) is analyzed. The content of the >80 mm class cannot be reduced to the required values without special crushing equipment. Initial data for the selection and design of screening and crushing...
The gas permeability, which is one of the most important requirements served by coke, is dependent largely on the size distribution of the coke at the various zones in the blast furnace. This papers deals with breakage of coke when it travels from wharf to blast furnace. In this study, six...
The measures adopted in the benzene department of byproduct-capture shop 1 at PAO Avdeevskii Koksokhimicheskii Zavod (AKKhZ) are discussed. During the reconstruction of coke production at the plant, valuable operational experience has been gained with a compact cooling system for the...
The reasons for the differences in coal-tar quality in byproduct-capture shops 1 and 2 at PAOAvdeevskii Koksokhimicheskii Zavod (AKKhZ) are explored. The influence of the below-roof temperature and the factors on which it depends is established.
The combination of coke cooling and batch preparation in a single system, by means of thermal tubes, has numerous economic, engineering, and environmental benefits. The energy and resources consumed in thermal preparation of the batch are much reduced.
