Calculation method of energy consumption ratio of waste heat power generation Calculation of waste heat power generation ratio See equation (1). ηfd = 0.1229 × β ecl x 100% (1) Where. ηfd - waste heat power generation ratio; 0.1229 --- Coefficient coal coefficient (equivalent coefficient); β - ton of clinker power generation, in kilowatt hours per ton of clinker (kW · h/t); ecl --- clinker comprehensive coal consumption, the unit is kilograms of standard coal per ton of clinker (kgce/t). 6.2 Calculation method of weight index for secondary energy consumption of different types of production line energy consumption evaluation 6.2.1 Determination of energy consumption of cement production line Cement production line energy consumption evaluation of secondary indicators weight value αc1 see Table 1. 6.2.2 clinker production line energy consumption evaluation of secondary indicators weight calculation method Clinker production line energy consumption evaluation of secondary indicators include raw fuel pretreatment, raw material preparation, fuel preparation, clinker firing, waste heat power generation and Auxiliary production system. Clinker production line energy consumption calculation calculation (2). αc2 = αc1 × 1.1055 (2) Where. αc2 --- clinker production line energy consumption evaluation secondary index weight value; αc1 --- cement production line energy consumption evaluation of the secondary index weight value, see Table 1; 1.1055 --- clinker production line energy consumption evaluation secondary index weight correction factor. 6.2.3 Calculation method of secondary index weight for energy consumption evaluation of cement grinding enterprises Cement grinding enterprise energy consumption evaluation of secondary indicators include raw fuel pretreatment, cement making, cement packaging, shipping and auxiliary production system. Calculation of Energy Consumption of Cement Grinding Enterprises (3). αc3 = αc1 × 8.8670 (3) Where. αc3 --- cement grinding enterprise secondary index weight value; 8.8670 --- cement grinding enterprise secondary index weight correction factor. 6.3 Evaluation of the evaluation of the evaluation of indicators 6.3.1 Management index Score calculation The three-level qualitative evaluation index of A, B and C included in the secondary index of cement manufacturing enterprise management index is adopted in the single score calculation Grading scoring principle, as shown in Table 2. Table 2 management indicators grading scoring table Production level A grade B grade C level lower than C level Corresponding score Sij 100 80 60 0 Note. Sij is the score corresponding to the different grades in the i-th secondary evaluation index (j corresponds to A, B, and C different grades). Final Management Indicators Individual scoring is multiplied by the corresponding weight value. 6.3.2 Calculation of energy consumption index The secondary indicators of energy consumption in cement manufacturing enterprises include A, B, C three quantitative evaluation index. According to the production situation, the index can be divided into positive Indicators and adverse indicators. forward indicators that the higher the value of the indicators of the lower energy consumption; reverse indicators that the lower the value of the indicators lower energy consumption. root According to their different types of calculation methods, in the individual score calculation, the calculation method in Table 3. Table 3 Energy consumption indicators to calculate the score table Production level A grade B grade C level lower than C level correspond Score Sij (I)] 60 [Xi-Cmin (i)]/[Bmax (i) -Bmin (i)] 60 20 (Xi-Cmin (i)]/[Cmax (i) -Cmin (i)] 0 (Cmax (i) -Xi]/[Bmax (i) -Bmin (i)] 60 20 [Cmax (i) -Xi]/[Cmax (i) -Cmin (i)] 0 Note. Xi is the actual value of the evaluation item for item i; Bmax (i) is the maximum value of the B-level reference range of the i-th indicator; Bmin (i) is the minimum value of the B-level reference range of the i-th indicator; Cmax (i) is the maximum value of the C-level reference range for the i-th indicator; Cmin (i) is the minimum value of the C-level reference range for the i-th indicator. 6.3.3 Calculation and evaluation of individual secondary evaluation indexes of cement manufacturing enterprises Cement manufacturing enterprises in the evaluation index of the secondary indicators to the enterprise in the assessment period actually reached the value of the basis of calculation to see (4). Pi = αi · Sij/100 (4) Where. Pi - i - level two evaluation index assessment score; αi --- the weight value of the secondary evaluation index of item i; Sij - the score corresponding to the different grades in the second grade evaluation index (j corresponds to A, B, and C different grades). 6.4 Comprehensive calculation of energy consumption of cement production The comprehensive evaluation value is calculated as (5). P = Σ i = 1 Pi (5) Where. P --- enterprise energy consumption comprehensive evaluation value, its value is between 0 ~ 100; Pi - i - level two - level assessment score; n - the total number of secondary indicators involved in the assessment.
