| 中文摘要: |
| 本文根据水泥厂用烟煤多为配煤的特点，以公司进厂烟煤数据为基础，参照经典经验公式，利用Excel数据分析工具建立数学模型，推导出适合公司的烟煤氢含量计算公式，对实测值与按经典经验公式和新推导公式的计算值进行统计对比，并进行置信分析，确定出新的推导公式满足计算精度要求，从而提高了氢含量计算值的准确度。 |
| 英文摘要: |
| According to the characteristics of bituminous coal used in cement plant, based on the data of the company's incoming bituminous coal, based on the classical empirical formula, the Excel data analysis tool is used to establish a mathematical model, and the formula for calculating the hydrogen content of bituminous coal suitable for the company is derived. The measured values are statistically compared with the calculated values of the classical empirical formula and the new derivation formula, and confidence analysis is performed to determine that the new derivation formula satisfies the calculation accuracy requirement, thereby improving the accuracy of the calculated hydrogen content. |
