Studying the dependence of quality of coal fine briquettes on technological parameters of their production

The study characterizes the role of coal in the fuel and energy balance of the Far East Region and points out the issue of losses of coal fines in the processes of coal mining, transportation and processing. To solve the problem of losses of coal fines, the mined coal is sorted into different size classes and fuel briquettes are produced from coal fines. Physical foundations are presented in short of briquetting solid combustible mineral resources. The dependences and variations of briquette compression strength limit are studied vs. charge humidity and briquetting pressure. Optimal parameters are retrieved for briquetting coal fines. The principal technological scheme is given of the process of briquette production. The developed technological solutions include sorting regular coal and briquetting coal fines, as well as the involvement of technogenic carbon-containing wastes from the hydrolysis production lines, plus residuals from oil refining.
