The blending with lowquality coal is 15% maximum in the wet system, and it arrives to 30% in the dry configuration. By converting coke ovens (50 t/h capacity) from wet to dry, a reduction of over 130,000 t/year of CO 2 can be reached; this corresponds to 8% of net reduction of CO 2 emissions in the atmosphere.

In coal bunkers and coal blending facilities, the coal goes through a moderate grinding process before being stored. Coal bunkers can contain thousands of tons of material. Their size and the dusty conditions make it difficult to accurately measure the amount of coal in the bunker or blending facility. There are also safety risks to personnel ...

Coal Blending. Coal blending is a process of uniformly combining two or more kinds of coking coal in appropriate proportions to obtain the required blended coal. It is a preparation process of coal charges before coking. Coal blending can ensure the quality of coke meets the requirements and also can reasonably utilize coal resources.

Coal blending can be performed at the mine site, on stockpiles, and in bins, bunkers, and silos (Arnold and Smith, 1994). There are a number of techniques that enhance the blending process, such as different ways of storage (circular stockpiles, longitudinal stockpiles), different procedures for stacking, and different processes of reclaiming.
