Where. ηfd – cogeneration energy consumption ratio; 0.1229 – power conversion coefficient of standard coal (equivalent coefficient); β – electricity generation per ton clinker; in kW•h/t; ecl – comprehensive coal consumption of clinker, in kgce/t. 6.2 Calculation method of second-level index weight for energy consumption evaluation on different types of production lines 6.2.1 Confirmation of second-level index weight for energy consumption evaluation on the cement production line The second-level index weight ac1 for energy consumption evaluation on cement production line can refer to Table 1. 6.2.2 Calculation method of second-level index weight for energy consumption evaluation on the clinker production line The second-level items for energy consumption evaluation on the clinker production line include crude fuel pre-treatment, raw meal preparation, fuel preparation, clinker burning, cogeneration and auxiliary production system. The calculation of energy consumption evaluation on clinker production line can refer to Formula (2). Where. ac2 – second-level index weight for energy consumption evaluation on clinker production line; ac1 – second-level index weight for energy consumption evaluation on cement production line, see Table 1; the calculation method can refer to Table 3. Table 3 -- Energy Consumption Index Calculation Score Form 6.3.3 Calculation for assessment score of single second-level evaluation index in cement manufacturing enterprise The second-level index in the evaluation index for cement manufacturing enterprise is based on the data that is actually reached by the enterprise during the assessing period; the calculation can refer to Formula (4). Where. Pi – assessment score or second-level evaluation index of the ith item; ai – weight value of second-level evaluation index of the ith item; Sij - the score corresponding to different classes in the second-level index of ith item (j is corresponding to Class-A, Class-B, or Class-C) 6.4 Calculation of energy consumption comprehensive evaluation value for cement manufacturing The calculation of comprehensive evaluation value can refer to Formula (5). Where. P – energy consumption comprehensive evaluation value of the enterprise, with 0~100; Pi – assessment score of the second-level index of the ith item; n – the total number of second-level indexes participating in the assessment. Manufacturing Situation Class-A Class-B Class-C Class-C Below Corresponding score Sij Positive index Reverse index NOTE. Xi is the actual value for the evaluation index of the ith item; Bmax(i) indicates the maximum value in the Class-B benchmark range of the ith item index; Bmin(i) indicates the minimum value in the Class-B benchmark range of the ith item index; Cmax(i) indicates the maximum value in the Class-C benchmark range of the ith item index; Cmin(i) indicates the minimum value in the Class-C benchmark range of the ith item index. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
