Abstract
The object of the research work was coal fines and processes of enrichment of Ekibastuz coal to produce fuel briquettes with increased calorific value and less ash content. Research, scientific substantiation of technology for obtaining high-calorific coal briquettes from fines of Ekibastuz coal, using various binders and the possibility of further coking, designing and manufacturing equipment for the implementation of technology, was made. The standard methods of theoretical and experimental research widely used in metallurgy, machine building, computer systems, etc. were used in the work. The characteristics of briquettes on bio-binding and on petroleum pitch with enrichers in the form of rubber-technical soot and anode dust of electrolysis cell for aluminum production have been established. It is revealed that the calorific value of briquettes is higher than that of Ekibastuz coal (Pavlodar region) by 20-40%, and the heating value is the highest for briquettes with an enrichment agent in the form of anode dust and a binder in the form of petroleum pitch (-NH combustion = 6840.8 kcal / kg). Briquettes on petroleum pitch with an enrichment agent in the form of anodic dust of aluminum electrolysis can be used as industrial briquettes for further use in metallurgy.
