ABSTRACT

Thermogravimetric studies of thermal destruction of individual stages of anthracite coal, biomass and their mixtures have been conducted. A comparison of the common methods of gravitogram approximation for individual stages of the process of thermal destruction is performed and the optimal ones are selected based on the analysis of the relative error. Kinetic constants are obtained, which allow determining the duration of individual stages of thermal destruction of the studied fuels, which can be used in calculations of burner devices.

KEYWORDS

solid biomass, co-firing, thermogravimetric analysis, combustion kinetics.
