3 Definition of energy balance of the whole enterprise
Enterprise energy balance is the energy balance based on the enterprise, including the balance of income and expenditure of various energy sources, and the balance between consumption and effective utilization and loss.
4 Method for energy balance of enterprise
4.1 Enterprise energy balance adopts statistical calculation method. When statistical data is not available, statistical data should be used according to special requirements. When the energy balance sheet is prepared, the energy source should be calculated and the statistical data should be complete and correct. The relevant data should not be wrong, missed or double-counted.
5.2 The physical quantity of various energy sources and the conversion standard coal should be separated as necessary. 5.3 The various energy numbers in the full balance sheet should be consistent with the actual income. The various energy numbers supplied by each workshop should be consistent with the corresponding energy quantities in the balance sheet. 6 Technical indicators of enterprise energy level 6.1 Energy indicators State Administration of Technical Supervision 1993-06-19 Approved 1994-02-01 6.1.1 Actual energy consumption per unit of product output shall be calculated according to formula (1): GA/T 3484-93 Where: F—physical energy consumption per unit of product output, t (tons> standard coal E, basic energy consumption, physical unit! The number of qualified products of a certain product produced during the period, physical unit. 6.1.2 The physical energy consumption per unit of output value (added value) is calculated according to formula (2):
Where: E—physical consumption per unit of output value (added value), t (tons) (standard coal) G—output value (added value) of the period in ten thousand yuan 6.1.3 Comprehensive system of unit output of products
Comprehensive energy consumption per unit of output of products is calculated according to GB2589 standard. 6.2 Energy and energy utilization indicators
6.2.1 Batch thermal efficiency
Equipment 6.2.2 Enterprise energy utilization rate The enterprise energy utilization rate is based on the various energy consumed by the enterprise and the effective utilization rate of the total primary energy consumption. The enterprise energy utilization rate is calculated according to formula (3) where: The enterprise energy utilization rate, %: The effective utilization energy of the enterprise, t (tons) (standard coal) The comprehensive energy consumption of the enterprise, t (tons) (standard coal) 6.3 Residual energy index 6 3.1 Residual energy resources The residual energy resources are calculated according to GB1028 standard. 6.3.2 Surplus energy resource rate
The surplus energy resource rate is the percentage of surplus energy resources in the total amount of various energy consumed by the enterprise. The surplus energy resource rate is calculated according to formula (4):
surplus energy resource rate,%;
Esurplus energy resource quantity t (tons> (accurate filling)
E-enterprise total energy consumption, t ((standard medium). 5.3.3 Surplus energy resource utilization rate
surplus energy utilization rate is the utilization rate of the surplus energy resources of the enterprise. The surplus energy resource utilization rate is connected with formula ( 5) Calculate, X100
Residual energy resource utilization rate,
E The amount of residual energy utilized, t(tons (standard medium). 2
Calculate the effective use of energy in the enterprise
GH/T3484-93
The effective use of energy in an enterprise refers to the energy required for the use of each energy source consumed by the enterprise at the end. 7.1 Effective use of energy for production
7.7.1 The energy consumed by the process to achieve the process requirements 7.1.2 The energy that must be consumed to meet the material transportation requirements. 7.2 Effective energy used for collection and absorption
When the energy consumption for collection and absorption is lower than the specified index, the actual energy consumption is the effective energy base; when it is higher than the specified index, the excess is not included in the effective energy consumption.
7.3 Effective energy used for lighting
When the power consumption for lighting is lower than the specified index, the actual power consumption is the effective energy base, and the higher power consumption is the effective energy base. When the energy consumption of transportation is lower than the specified index, the actual energy consumption is regarded as the effective energy consumption. When it is higher than the specified index, the excess energy is not counted as the effective energy consumption.
7.5 Idle operation of production equipment and empty-load operation of transportation vehicles do not effectively utilize energy. 8. Enterprise energy balance report
The enterprise energy balance report should include the following charts and energy analysis. 8.1 Enterprise energy balance sheet (Table 1). 8.2 Enterprise energy consumption table (Table 2)
8.3 Enterprise energy balance sheet (Table).
8.4 Efficiency table of main energy-consuming equipment (Table 4), 8.5 Energy table of main products (Table 5).
8.6 Enterprise Energy Flow Diagram
According to G 27 standard, draw the enterprise energy flow diagram accurately.
8. Energy Usage Analysis
8.7.1 Analyze the comparison and change reasons of the enterprise energy usage indicators between the reporting period and the previous period and previous years. 8.7.2 List the surplus energy resources within the enterprise, the surplus energy quota rate and the utilization of surplus energy resources. 7.3 Make an energy rationality analysis based on the source flow situation. 7.4 According to the energy consumption index, equipment use belt analysis and GB3485, GB3485+ line energy-saving power and parts, and put forward energy-saving application plan
For the energy-saving measures taken, make energy-saving effect and economic benefit evaluation analysis, 9 The energy balance of the enterprise should be organized into technical files GR/T3484-93
