Abstract

In this study the thermal gravimetric and differential thermal analysis (TGA&DTA) and X-ray diffraction used to evaluate the thermal properties of solid residues of milled peat after extraction of humus substances to determine its compliance with the requirements for fuels. It was shown that the temperature ranges  of  thermal   decomposition of organic substances in the residue considerably wider than those of the peat, and their values are directly depend on the extraction temperature. It was found that new solid phases in residues appeared at high temperature in the presence of calcium and silicic oxides and sodium ions. Also the thermal effects during the thermal decomposition of organic matter and peat residue were compared. The method of use residues as fuel was proposed.
