This Standard applies to the energy consumption evaluation in the flat glass manufacturing process of enterprises that produce flat glass products that comply with GB 11614. 2 Normative references The following documents are indispensable for the application of this document. For dated references, only the dated version applies to this Standard. For undated references, the latest edition (including all amendments) applies to this document. GB 11614, Flat glass GB/T 12497, Three-phase induction motors economic operation GB/T 16664, Monitoring and testing method for energy saving of power supply distribution system of industrial enterprise GB 17167, General principle for equipping and managing of the measuring instrument of energy in organization of energy using GB/T 23331, Energy management systems - Requirements GB/T 24851, Specification for equipping and managing of measuring instrument of energy in building material industry GB/T 39773, Energy consumption test technical regulation for flat glass manufacturing JC/T 488, Determination and calculation method of thermal balance for glass furnace 3 Terms and definitions The following terms and definitions are applicable to this document. 3.1 Cogeneration energy consumption ratio During the statistical period, the ratio of the flat glass-generated energy per ton in the cogeneration system to the melting fuel consumption, which is expressed by ηfd. 4 Evaluation scope and testing 4.1 Evaluation scope The evaluation scope shall be implemented in accordance with the test scope that is specified in GB/T 39773. 4.2 Evaluation testing Complete the energy consumption testing according to GB/T 39773. 5 Evaluation index system and requirements 5.1 Evaluation index system See Figure 1 for the evaluation index system. 6.2.3 Enterprise's grade-2 index score calculation The comprehensive score of the grade-2 index evaluation in the evaluation indexes of flat glass manufacturing enterprises is based on the actual value of the grade-2 index during the evaluation period of the enterprise. The calculation is shown in Formula (2): Where: Pi -- evaluation score of the ith grade-2 evaluation index; αi -- weighted value of the ith grade-2 evaluation index; Sij -- score corresponding to different grades in the ith grade-2 evaluation index (j corresponds to different grades of A, B, C). 6.3 Energy consumption comprehensive evaluation and calculation The calculation of the comprehensive evaluation index is shown in Formula (3): Where: P -- comprehensive evaluation index of enterprise energy consumption, whose value is in 0 ~ 100; Pi -- evaluation score of the ith grade-2 index; n -- total number of grade-2 indexes that are involved in the assessment. 7 Evaluation report The evaluation report mainly includes: a) The overall situation of the flat glass production line, including production scale, product variety, specifications, production time and/or modification (if any) date, system host configuration, and operating status description; b) Evaluation task and purpose requirements; c) Evaluation basis and standards; d) Evaluation method description; ......
