Исследовать процесс горения двух углей разной степени метаморфизма и их смесей с применением термогравиметрического анализа, основанного на изменении массы и скорости изменения массы в процессе нагрева топлив. Определить основные характеристики топлив и процесса горения (температуры воспламенения и выгорания коксового остатка). Провести качественный анализ поверхности топливных частиц двух разных углей с помощью сканирующей электронной микроскопии на наличие пор и трещин. Определить склонность к шлакованию угольных смесей. МЕТОДЫ. При решении поставленных задач применялся термогравиметрический метод, электронный метод и метод расчета, на основе проведенного валового химического анализа минеральной части углей и их смесей. РЕЗУЛЬТАТЫ. В статье представлен краткий обзор по сжиганию непроектных топлив на теплоэлектростанциях. Приведены результаты технического и элементного анализа черногорского каменного угля и балахтинского бурого угля. Описана методика определения температуры воспламенения и выгорания коксового остатка. Представлены термограммы процесса горения двух углей разной степени метаморфизма и их смесей. Определены основные характеристики их горения. Показан качественный анализ поверхности топливных частиц на наличие пор и трещин. Проведен расчёт склонности к шлакованию угольных смесей. ЗАКЛЮЧЕНИЕ. И черногорский и балахтинский уголь имеют высокий выход летучих веществ и среднюю теплоту сгорания. По степени метаморфизма отличаются незначительно, показатели их технического и элементного анализа близки по своим значениям. Термогравиметрический анализ показал более раннее воспламенение балахтинского бурого угля по сравнению с черногорским каменным углем. При увеличении доли балахтинского угля в угольной смеси профиль кривых горения смещается в область более низких температур. Добавление 25% балахтинского угля снижает температуру воспламенения черногорского угля на 16%, с увеличением доли балахтинского угля в смеси температура воспламенения не изменяется. Расчет склонности угольной смеси к шлакованию применяя основные оксиды, содержащиеся в минеральной части золы исследуемых углей, показал, что балахтинский уголь имеет высокую склонность к шлакованию топочных экранов в отличие от черногорского каменного угля, поэтому увеличение массовой его доли в угольной смеси увеличивает склонность к шлакованию топочных экранов.</p></abstract><trans-abstract xml:lang="en"><p>THE PURPOSE. Consider the combustion process of two coals of different degrees of metamorphism and their mixtures using thermogravimetric analysis based on the change in mass and the rate of change in mass during the heating of fuels. Determine the main characteristics of fuels and the combustion process (temperature of ignition and burnout of the coke residue). Determine the tendency to slagging of coal mixtures. METHODS. When solving the tasks, the thermogravimetric method (TGA). RESULTS. The article provides a brief overview of the combustion of non-design fuels at thermal power plants. The results of technical and elemental analysis of Chernogorsk bituminous coal and Balakhta brown coal are presented. A technique for determining the ignition temperature and burnout of the coke residue is described. The thermograms of the combustion process of two coals of different degrees of metamorphism and their mixtures are presented. The main characteristics of their combustion have been determined. A qualitative analysis of the surface of fuel particles for the presence of pores and cracks is shown. The calculation of the tendency to slagging of coal mixtures has been carried out. CONCLUSION. Thermogravimetric analysis showed an earlier ignition of the Balakhta brown coal in comparison with the Montenegrin bituminous coal. With an increase in the proportion of Balakhta coal in the coal mixture, the profile of the combustion curves shifts to the region of lower temperatures. The addition of 25% Balakhta coal reduces the ignition temperature of Chernogorsk coal by 16%, with an increase in the proportion of Balakhta coal in the mixture, the ignition temperature does not change. Balakhta coal has a high tendency to slagging furnace walls, in contrast to Chernogorsk coal, therefore, an increase in its mass fraction in the coal mixture increases the tendency to slagging furnace screens.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>уголь</kwd><kwd>степень метаморфизма</kwd><kwd>угольные смеси</kwd><kwd>шлакование топочных экранов</kwd><kwd>термогравиметрический анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coal</kwd><kwd>degree of metamorphism</kwd><kwd>coal mixtures</kwd><kwd>slagging of furnace walls</kwd><kwd>thermogravimetric analysis (TGA)</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">«Исследование выполнено при финансовой поддержке Красноярского краевого фонда науки в рамках проекта «Концепция развития теплоэнергетики Красноярского края»».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zhou H., Bhattarai R., Li Y., et al.
