Experimental and theoretical investigation of the combustion heat of complex powders

摘要

The main goal of the presented work was to check whether it is possible to use a thermo-chemical model to predict the heat of combustion of complex powders and to determine the calculation conditions that ensure obtaining the heat close to the calorimetric one. Calo-rimetric measurements of the heat of combustion of selected complex powders was carried out and their combustion characteristics were obtained from thermochemical calculations. The combustion heats determined experimentally and theoretically were compared. On the basis of the analysis of the obtained results, the approximate temperature of "freezing " of the composition of combustion products was established.
