Abstract

Global Ispat Koksna Industrija"d.o.o. (GIKIL) developed Coal blend models linking interdependent input blend coal properties to output coal quality. The invention arose at the necessity of achieving a very high quality in coke quality parameters (about 5nos) with a proper blend mix of different coals. The models have been developed based on the operating data for the last 6 years for the different Coal Blend quality parameters and Coke quality. The models consist of different correlation equations for each output quality of coke with different blend quality parameters. Thus by knowing the input qualities of coals used in coke manufacture, the expected coke quality can be determined. Once the coke quality is predetermined, it allows planning the blend mix of different coals for the required blend quality and accordingly purchasing coals and manufacturing coke as per required quality.
