COAL CHARGE FOR BLAST FURNACE COKE PRODUCTION

摘要

Coal charge for blast furnace coke production in the process of so-called high-temperature carbonization consisting in heating of the mixture of different types of coal in coke battery at temperatures ranging above the temperature of 1000 ° C in oxygen-limited atmosphere, characterized by containing 0.1 to 30 % by weight of non-caking addition of brown coal, 70 to 99 % by weight of the basic component of black coal and the rest of possible accompanying solids, whereas the addition of non-caking brown coal consists of brown1 coal Containing 35 to 55 % by weight of volatile combustible matter (V daf), 10 to 17 % by weight of tar (Td sk), 4 to 7 % by weight of ash (Ad) and 15 to 30 % by weight of water (Wt r).
