The purpose of this paper was to investigate the relationship between ash composition and ash fusion characteristic temperatures for some Turkish lignites. The lignite samples used are from different areas in Turkey. Regression analysis was used to relate the ash composition to the ash fusion behaviour. The results suggest that the chemical composition has a significant effect on the ash fusion temperatures. To consider Fe2O3 as an acidic ash constituent makes the realtionships between the selected ash composition parameters and ash fusion temperatures clearer. 相似文献

ABSTRACT In this study DTA and TGA were applied to some fossil fuels. Peat, lignite, bituminous coal, anthracite, oil shale and asphaltite were heated at a constant 15 °C/min up to 1000 °C under nitrogen atmosphere. The DTG curves of the samples were derived using the TG curves. The results are compared and discussed. 相似文献
