The article analyses the by-products formed during the combustion of briquettes produced under the following parameters: nozzle diameter Dn = 25 mm, compressive force of the variable-pitch screw Fc = 2.4 kN, working chamber diameter Dw.c = 100 mm, addition of 10–15% water and binder for briquetting, a 9:6% aqueous mixture of alcohol stillage and paraffin waste, briquetting temperatures of 90, 95, and 100 °C, mixing time of 20 minutes with thermal treatment, and addition of hard and soft nutshells in the range of 10, 20, and 30% relative to the total mass. The combustion analysis of the obtained briquettes was carried out in accordance with GOST 12.1.005-38.
The study established that preliminary drying of coal powder and heat-assisted mixing of the blend partially reduce the volatile gases present in the briquette composition. It is explained that this process can be controlled through monitoring or by applying dust–gas cleaning methods. However, recommendations are provided on the complexity of monitoring various emissions generated during the combustion of finished briquettes in compliance with MPC standards.
