An analysis of publications containing information on the differential thermal analysis (DTA) method history, its essence and some aspects of practical use for the analysis of of solid fuel thermal destruction and combustion was carried out. A method of laboratory research based on the principles of DTA, characterized by a high heating rate (up to 2000 degr/min), is proposed. The possibility of using the proposed technique for comparative analysis of thermal destruction the kinetics for pulverized coal fuel (PVP) mixtures blown into blast furnaces to replace coke is shown.
