燃煤电厂煤种爆炸特性研究

Research of Coal Explosivity in Coal-fired Power Plants

对山东区域内某电厂的入炉煤和入厂煤爆炸特性进行分析,根据爆炸性指数将煤种进行了详细分类,分为极易爆炸煤种、较易爆炸煤种、易爆炸煤种和不易爆炸煤种。根据煤样的工业分析结果和低位发热量采用最小二乘法拟合得出了煤粉爆炸性指数的线性公式,并对煤粉爆炸性指数预测值进行了误差分析,分析显示线性公式能够较好的预测煤粉的爆炸性指数。

This paper analyzes the explosivity of the coal as fired and coal as received.According to the explosive index,the coal can be divided into the most explosive coal,the more explosive coal,explosive coal and normal coal.According to the proximate analysis and net calorific value of coal fitted linear formula of explosive index by the method of least squares,and the error of coal prediction explosive index was analyzed.The formula could be used to predict explosive index of coal.
