Abstract:

Based on the properties analysis of long flame coal.We added long flame coal to replace part of 1/3 coking coal and gas coal for cokemaking test according to the present coal blending scheme.The result shows that long flame coal can replace part of 1/3 coking coal and gas coal for cokemaking when increasing the mass percentage of fat coal. This will be beneficial for reducing sulfur and ash content in coke，saving the coking coal resources and lowering the coal blending cost.
