Abstract:

This paper conducts experimental coke making respectively by top charging and stamp charging method with 6 kinds of single coal and their 4 kinds of blended coal in 2kg test coke oven,and studies the impact on coke quality.The result shows that stamp charging has increased the bulk density and improved the caking property and further improved coke quality.On condition of ensuring the coke quality,more quantity of weakly caking coal such as gas coal,lean coal and meager coal could be blended.
