3 Definition of product unit output energy consumption quota GB1272391
3.1 Product unit output energy consumption quota is formulated for energy accounting units, with qualified product units as accounting units. Energy consumption limit.
3.2 The products under investigation can Whether it is a final product, an intermediate product or a primary product: For some industries or processes (procedures), the single raw material processing volume or unit workload can be used as the accounting unit. 4 Classification of energy consumption quotas for unit output of products 4.1 Energy consumption quotas for unit output of products include single energy consumption quotas, comprehensive energy consumption quotas and comparable energy consumption quotas.
4.1.1 Single energy consumption quotas for unit output of products refer to the consumption limit of a certain energy or energy-consuming working fluid (such as water, oxygen, etc.) when producing a unit of qualified products.
4.1.2 Comprehensive energy consumption quotas for unit output of products Quota refers to the comprehensive energy consumption limit determined in accordance with the provisions of GB2589 when producing qualified products per unit.
4.1.3 Product unit output comparable energy consumption quota, based on the comparable factors affecting product unit output energy consumption in order to achieve product energy consumption comparability in the cylinder industry, the comparable product unit output energy consumption quota is formulated. 4.2 Product unit output energy consumption quota includes three types: product unit output direct energy consumption quota, product unit output enterprise energy consumption quota and product unit output energy consumption supply quota. 4.2.1 Product The direct energy consumption quota per unit of output is the energy consumption limit per unit of product formulated for the main production system. 4.2.2 The enterprise energy consumption quota per unit of product output is the energy consumption limit per unit of product formulated for the enterprise production system including the main production system, auxiliary production system and ancillary production system. 4.2.3 The energy consumption supply quota per unit of product output refers to the energy consumption quota per unit of product output during the planned statistical period. Approved by the State Administration of Technical Supervision on February 1, 1991 and implemented on December 1, 1991
GB 12723—91
On the basis of the above, taking into account the possible changes of various internal factors affecting energy consumption, the control indicators of energy supply are formulated. 5. The use of energy consumption quotas per unit of product output 5.1 The energy consumption quota per unit of product output is the main basis for measuring the energy consumption technology level of production products. 5.2 The energy consumption quota per unit of product output is the main indicator for the state to assess the energy economic benefits and energy management level of regions, industries and enterprises. This quota can use single energy consumption indicators and comprehensive energy consumption indicators at the same time, or use one of the indicators alone. 5.3 The energy consumption quota per unit of product output is the main basis for formulating production plans and energy supply plans, and is the control figure for the purchase, management and allocation of national energy supply and enterprise energy plans. This quota only uses single energy consumption indicators. 5.4 All industries and regions should use the degree of reaching the comprehensive energy consumption quota of enterprises or certain single energy consumption quotas as the main basis for energy conservation and over-fines of enterprises.
5.5 All industries and regions should use the comprehensive energy consumption quota of enterprises under comparable conditions or the level (advanced level) and degree of achievement based on such single energy consumption quota as the seven key measurement standards for enterprise energy grading and upgrading. 5.6 All units that have formulated quotas should compare the actual energy consumption with the energy consumption quota to calculate the energy saving and energy saving rate, and include them in the enterprise energy statistical reporting system:
6 Detailed formulation of energy consumption quota per unit output of products 6.1 Principles of formulation: The formulation of energy consumption quotas should comply with the principles of scientific rationality, encouraging advanced, spurring backwardness and simplicity and practicality, and should promote scientific energy management and rational use of energy and promote technological progress on the basis of ensuring product quality, safety and environmental protection requirements. 6.2 The basis for formulating the energy consumption quota per unit of output of products: a. The statistical data of energy consumption measurement in the past three years and the best historical data; b: The survey of the actual production technology status and the test and quantity data of energy-consuming equipment; . The development trend of production technology and process, the implementation of energy-saving technical reform d. The energy consumption data under the same production conditions in the same industry, with special attention to the status of advanced domestic and foreign levels. 6.3 Preparation method: The basic method for preparing the energy consumption quota per unit of output of products is the mathematical statistical analysis method based on statistical measurement data.
6.3.1 The calculation formula of the energy consumption quota per unit of output of products is: N=N
Where: N—Energy consumption quota per unit of output of products: 1
N, the actual energy consumption per unit of output of products in normal production status, can be obtained by the average value of the energy statistical measurement data of the enterprise in the past three years,
Considering the correction coefficient of changes in production technology cases and deviation of working conditions from normal production status. The value of the product is proposed by the enterprise and approved by the industry.
The enterprise should decompose this quota layer by layer to the production grassroots. 6.3.2 Enterprises can also use the energy consumption quota of each energy-consuming process (procedure) in each production system (main production system, auxiliary production system and subsidiary production system) as the basis, and integrate them layer by layer to form the energy consumption quota of the product unit output. The formulation of the energy consumption quota of the process (procedure) can adopt mathematical statistics, actual measurement method or technical calculation method. 6.3.3 When the industry formulates the energy consumption quota of the unit output of comparable products of enterprises of the same type, the calculation formula is: Ne -Ni - +

Where: N. The energy consumption quota of the unit output of the product: N—the industry benchmark quota of the energy consumption of the unit output of the product, which is taken as the weighted average of the actual energy consumption of the unit output of comparable products of the enterprise of this type in the past three years;
Grade classification coefficient. It shall be determined by the industry according to the proportion of the national special grade, first grade, second grade, provincial and municipal grade and qualified grade stipulated by the energy competent department.
GB 12723-91
6.3.4 The quota of energy consumption per unit of output of a product is calculated as follows: N -N. 1-4.
Wherein: N. — Quota of energy consumption per unit of output of a product: N is the same as 6.3.1
The energy consumption of an enterprise that is not included in N. mainly refers to storage loss and in-transit loss. (3
6.4 The revision of the quota of energy consumption per unit of output of a product shall be based on technological progress, changes in the variety or quality of raw materials and energy, changes in product structure and production scale, and the increase or decrease of environmental protection measures. In order to scientifically conduct the revision, it is required to analyze each major factor affecting energy consumption and express its degree of influence with a numerical relationship. 7 Procedures and approval for the formulation of energy consumption quotas per unit of output of a product 7.1 Energy management authorities at all levels shall stipulate that products that require assessment and monitoring of energy consumption shall formulate quotas for energy consumption per unit of output of a product, and implement hierarchical management by industry, department, and region from top to bottom. 7.2 The energy consumption quota per unit of product production shall be formulated by the competent department of the industry, and after soliciting the opinions of the energy accounting units, it shall be submitted to the superior for review and filing, and then issued for implementation.
7.3 The energy accounting units (units) shall decompose and implement the issued energy consumption quota to the lower-level energy-saving units (units). 7.4 The quota change may be proposed by the energy-consuming unit (unit) or the competent department. After re-verification according to the procedures of 7.2 and 7.3, the new energy consumption quota shall be implemented from the next statistical year. 7.5 The energy consumption supply quota shall be reported by the enterprise to the competent department and the energy supply department every year, and shall be issued after review and approval by the relevant departments.6 The competent department shall conduct regular review and certification of the implementation of energy consumption quotas.
