A Coal-Blending Model: A Tool for Better Coal Blend Preparation
A coal-blending model has been developed using relationships between coal and coke quality parameters. This coal-blending model gives a least-cost coal blend for the desired coal blend quality in terms of ash, volatile matter, mean maximum reflectance, and coke quality based on the coke strength and ash content. The model takes into account …
