In order to intensify heat and mass transfer processes and reduce dust removal on a rotating ramjet drum for drying coal of the D brand, it was proposed to use a method of acoustic impact during the formation of its field in the working space using two Hartmann whistle type emitters installed on the end surface of the unloading chamber. Based on experimental data on changes in the material and thermal balances, it was found that the use of acoustic field energy during the operation of the drying drum is accompanied by an increase in its dry coal drying drum productivity by4.76 rel. %, the amount of exhaust gases decreases by 8.98 rel. % and the amount of dust emitted by 5.75 rel. % with an increase in the amount of removed moisture from coal by 12.5 %. With increased fuel heat consumption by 14.4 rel. % heat losses with waste gases are reduced by 12.61 rel. %, with a dust of 9.41 rel. % and total heat loss to the environment by 6.25 rel. %. With a decrease in the productivity of the drying drum for raw coal by 1.75-1.98 times and the use of acoustic field energy, the yield of dry coal increases by 12.06 rel. %, the proportion of fuel oil by 108 rel. %, the dust yield by 71.89 rel. %, dust yield at 71.89 rel. % with a reduction in the share of volatile in the heat treatment process by86.11 rel. %, recirculate by 17.48 rel. %, the amount of gases removed by 35.5 rel. %, the degree of moisture removal by 11.14 %. At the same time, the thermal efficiency of the unit practically does not change (0.987 rel. %). The use of acoustic field energy is a low-cost and highly efficient way to improve the thermal operation of the drying drum.
