Production of metallurgical coke
专利汇可以提供Production of metallurgical coke专利检索，专利查询，专利分析的服务。并且PURPOSE: To make it possible to decrease the variability of coke quality and to prevent the dusting of powdered coke and the overflow of tar from the oven cover by providing a chamber oven-type coke oven with a plurality of feed hoppers and regulating the properties of the coal fed to each hopper according to the carbonization characteristics of the coke oven.
CONSTITUTION: A feed coal 5 formed by mixing a coal blend with a coal briquette in an arbitrary ratio is fed to feed hoppers 1-2 and 1-3 provided inside the coke oven 2 along the length of the oven. A coal blend 4 having a volatile content lower than that of the coal blend in the feed coal 5 and better cokability is fed to the feed hoppers 1-1 and 1-4 on the side of the oven cover 3, and the feed coal 5 is fed to its inside and carbonized to produce metallurgical coke. In this way, a decrease in the bulk density of feed coal on the oven side 3 at which the temperature falls and an improvement in the thermal conductivity can be effected, so that the temperature of coke can rise, the coke strength can be improved, and the dusting is decreased.
