The paper presents a technique for proximate and ultimate analyses of solid fuels and coal tars by integrating the simultaneous thermal analysis and mass spectrometry. The technique for the ultimate analysis is based on the analysis of components of the gas phase that is formed during combustion of the studied samples in oxygen. In the analysis of coal tars, the inert filler is used for their uniform evaporation and oxidation. The developed technique was tested on the black coal sample. The obtained results are consistent with the standard technique for ultimate analysis based on ASTM 3172-76. The paper shows a good agreement of the results of analysis by these two techniques. The paper also illustrates the applicability of the developed technique to studies on a wide range of solid fuels.
