摘要
选取某燃煤电厂2421批次贵州无烟煤的工业分析及发热量测定结果,利用多元线性回归分析,建立贵州无烟煤的低位发热量计算数学模型。通过对数学模型的统计检验及数学模型计算值与实测数据的对比分析,证明该数学模型具有较高的正确性与实用性,建议可将此模型作为贵州地区燃煤电厂对贵州无烟煤质量验收的辅助方法。
2421 groups of historical proximate analysis data and calorific value data of Guizhou anthracite coal in a coal-fired power plant were chosen to build calculation mathematical model of net calorific value of Guizhou anthracite coal by using multiple linear regression.Through the statistical test of mathematical model and comparison between calculation result of mathematical model and measured data,it was proved that the mathematical model had high correctness and practicability,so it was suggested that this model could be used as the helper method for Guizhou anthracite quality check and accept in Guizhou coal-fired power plant.
