Rapid calculation and analysis of furnace coal quality parameters under power coal blending

围绕燃煤电站入厂煤化验与动力配煤掺烧等环节,采用t检验法以及数据拟合得到混煤煤质计算方法,建立动力配煤掺烧下的入炉煤质快速计算模型。开展入炉煤质与入厂煤化验结果、配煤掺烧下的混煤煤质的关联分析,快速确定入炉煤的低位发热量、挥发分和硫分等重要煤质数据,并与入炉煤化验结果进行误差分析。研究结果有助于实时获取燃煤机组入炉煤质数据,对电厂提高锅炉运行水平和实现锅炉减污降碳协同控制意义重大。

Focusing on the links of incoming coal test in coal-fired power plant and power coal blending,the t-test method and data fitting are used to obtain the calculation method of blended coal quality,and a rapid calculation model of furnace coal quality under power coal blending is established.The correlation analysis between furnace coal quality and incoming coal assay results,blended coal quality under coal blending model are carried out,and the important furnace coal quality indicators such as low calorific value,volatile matter and sulfur content of furnace coal are quickly determined,compared with the test results of the incoming coal quality.The research results are helpful to obtain the real time coal quality data of coal-fired units,which is of great significance for the power plant to improve the boiler operation level and realize the coordinated control of pollution reduction and carbon reduction.
