Selecting efficient parameters for the coke charge of shaft-type melting furnaces

  • Published:
Metallurgist Aims and scope

It is shown based on studies of the changes in the composition of the gases and temperature in the preliminary charge that the performance indices of coke-fired shaft furnaces are determined by the conditions under which the oxidizing zone is formed so as to produce the greatest possible amount of heat. It is shown that the size of this zone increases with an increase in the rate of filtration of the air blast, enrichment of the blast with oxygen, and the use of low-activity coke in the form of lumps of limited size. To maximize the reheating of the melt, it is necessary to increase the average size of the lumps and the flow rate of the air blast in order to increase the height of the preliminary charge.
