Application of the Mechanical and Pressure Drop Tests to Determine the Sintering Temperature of Coal and Biomass Ash

The aim of this paper is to investigate the mechanical properties coal and biomass ash during sintering process. For study, bituminous coal, lignite, wheat straw, barley rye straw were selected. proximate, ultimate, oxide analyses performed. from these fuels was prepared in a special way that ensured physicochemical invariability initial state mineral matter biomass. purpose selection obtain widely available clearly diversified materials. Based on results composition ultimate analysis most common deposition, indices determined. Certain conflict index indications observed. Then, test pressure drop During test, fracture stress as function temperature measured. before behind sample measured temperature. Both tests showed characteristic changes (the occurrence maximum curve inflection point at curve) dependencies nearly same temperatures. These compared with deformation (IDT) standard Leitz method. A linear relationship between temperatures determined by IDT obtained. obtained are promising terms application methods (fracture test) early stage prediction slagging/fouling risks.
