摘要：Known methods for the production of fuel briquettes are studied and an analysis of their qualitative characteristics is carried out in the present work. Based on the analysis of existing methods, pilot briquetting of a mixture of PJSC “Koks” coal and coke dust with various types of binder was carried out. Within the framework of studies, the main requirement for raw materials was the absence of demand for it in the market and in the technological processes of existing industries. It has been established that substandard urea is the best binder of the considered ones, since briquettes with its use have high strength and low sulfur content. Comparative briquetting by single and impulse pressing methods was carried out. It is shown that greater briquette strength is achieved by impulse pressing method. It has been established that the process of utilizing finely dispersed carbon-containing wastes is aimed not only at obtaining a new marketable type of fuel and at saving natural resources, but also at improving the environmental situation through the rational use of secondary material resources.
