| Abstract: | The pyrolysis, ignition and burnout characteristics of Liuzhihua' s coal and Loudi's coal and their blends were studied by thermogravimetric analysis. The experimental results show that there were different ignition temperatures and combustibility for both the blended coals and the parent coals. A factor S' is suggested to evaluate integrative characteristics of ignition and burnout. The variation of S' with the change of the blended ratio reveals a strong dependence on blending ratio, which provided the theoretical forecast for the integrative trend of the combustion performance and the burnout characteristic of these coals. |
