The work aimed to study the process of burning coal briquettes with polymers. As the object of the research, the coals of Kazakhstan deposits were applied. The methodology of the study included theoretical and computational studies on the applied significance of coal processing, analysis by physicochemical research methods, pressing, drying and briquetting of coal with binders. It is shown that the briquettes combustion takes place stepwise and is characterized by a stationary regime. This is due to the mutual influence of the stages of pyrolysis of polyolefins and combustion of coke residue of substandard coal. In the combustion zone, the temperature did not depend on the content of polyethylene and was 400–500ºC in the coal burnout zone. The optimal compositions of briquettes supporting the combustion temperature of 1300°С were determined: coal-40 %, clay-20 %, polyethylene-40 %. Adding up to 20% clay to the polymer and coal mixture led to the formation of a combustion wave structure with symmetric temperature profiles. Thermogravimetric analysis shows that polyethylene plays the role of the initiator of combustion, burning at   500ºC, and in the future does not affect the maintenance of the combustion temperature of the briquette. The perspective of the results obtained is the possibility of utilization of low-demand coals of various brands of Kazakhstan deposits, which are waste of coal mining and coal enrichment with further production of coal briquettes of the required quality. Coal briquettes made from substandard coals with a multi-polymer binder, from chemical production waste have a higher calorific value, are mechanically robust during prolonged storage, do not crumble in the furnace until complete combustion, and are waterproof. These advantages determine their use for the population, as well as for various purposes of industrial economy, metallurgy and chemical industry.
