Study on Simultaneous Thermal Analysis Technology in Coal Quality Evaluation and Classification Identification
摘要
Abstract
Abatract: Three kinds of methods such as the arbitration method (GB/T 212-2008), macro thermogravimetric method (Marco-TG) and simultaneous thermal analysis (STA) were used to analyze the various origin area of coal products. The results showed that under the good sample preparation condition of coal, the Marco-TG and arbitration method coincided with the result of the coal proximate analysis, the results of the STA fluctuated relatively large, as using for rapid semi-quantitative evaluation of coal quality; According to the lignite, bituminous and anthracite combustion thermodynamic characteristics of differential scanning calorimetric curve, the classification of the three kinds of coal was discussed preliminarily, which promoted the import and export trade of coal product.关键词
