Abstract

In this work, heat transfer model in a coke oven with blended coal was developed and analyzed using a numerical method. The developed analysis model was verified by comparing the results with data available in the literature. After calculating the amount of heat consumed according to the change in the content, the amount of energy consumption for each condition and optimal operating conditions were suggested. Consequently, the optimal conditions for coke dry flow were derived to be 5.32 Mcal/ton_coal at a wall temperature of 1,050°C, 11.08 Mcal/ton_coal at a moisture content of 7.5%, and 10.68 Mcal/ton_coal at a charge of 700 kg/m3.
