Abstract

In terms of specific energy consumption, heat treatment of magnesite in shaft furnaces is a very difficult process allowing reaches the desired characteristics of processed magnesite substances only in increased energy consumption. The main reason is nonuniformity of sintering temperatures in the cross section of the shaft furnace. The lowest sintering temperature is achieved in the centre of the furnace. The reason is that no fuel is directly given to the middle of the furnace due to potential flow and transfer of heat from the surrounding layers is very limited. The new concept is based on the use of coke charged to the central part of the furnace. The considerable balancing of the maximum temperature is reached by combustion of coke by secondary air passing through the central part of the furnace. The results of experiments confirmed the possibility of using coke, achieving a substantial improvement in the shaft furnace work.
