The subject of research in this work is the processing of waste coal fines using a pyrolysis plant. The aim of the study is to obtain semi-coke and pyrolysis gas in the process of processing waste coal fines without oxygen. The process of thermochemical processing of coal fines is carried out by the principle of embedding a pyrolysis unit in a pyrolysis unit, or a second pyrolysis unit of a reduced size is installed inside the improved design of the pyrolysis unit using a specially withdrawn hole. To obtain the result of the study, the main pyrolysis unit, first, we will load the main pyrolysis unit with coal and then install the built-in (new) pyrolysis unit by preloading it with coal fines, and then we will make connections with the outlet pipe and fully load the main pyrolysis unit. We attach a distributor tee, a waste material container and a receiver for collecting pyrolysis gas to the outlet pipe. Experimental research is carried out on the coals of the Abshyr-ata and Kozho-kelen deposits, and for the reliability of the obtained research result, we will measure the main parameters of the studied coals until the final product is obtained.

We attach a distributor tee, a waste material container and a receiver for collecting technical gas to the outlet pipe. Experimental research is carried out with coals of the Abshyr-ata and Kozho-kelen brands, and for the reliability of the obtained research result, we will measure the main parameters of the studied coal grades until the final product is obtained. With the help of this unit, the process of upgrading waste of coal fines and low-grade coals of Kyrgyzstan is carried out. The developed installation can be used in the heat and power industry of the Republic and research institutions.
