Abstract

The work investigated the thermal behavior of Borodino coal, brown coal coke and mixed fuel, consisting of 80 % Borodino brown coal and 20 % brown coal coke during the combustion process using thermogravimetric analysis. The chemical composition of the samples is presented. When analyzing the TG-DTG curves, combustion characteristics were determined, such as: ignition temperature (Ti) and coke burnout temperature (Te), flammability index, integral combustion parameter. To determine Ti and Te, the technique of crossing the TG and DTG curves was applied and justified. An electron microscopic study of the cross-section of a lignite coke particle has been carried out. The results of the study showed that the addition of lignite coke to brown coal has a positive effect on its combustion characteristics
