NB/T 10184-2019The norm of energy consumption per unit product of porcelain insulators (English PDF)

3.1 Comprehensive energy consumption of porcelain insulator products

During the statistical reporting period, the actual amount of energy consumed and lost by the porcelain insulator production system shall be calculated in accordance with GB/T 2589.

The calculation method and unit are respectively converted to the sum.

Note: This does not include the energy consumed by the construction of infrastructure technological transformation projects, the production and utilization of non-ceramic insulators in the production area, and the energy output.

3.2 Comprehensive energy consumption per unit product of porcelain insulator

The ratio between the comprehensive energy consumption of porcelain insulator products and the quality of qualified porcelain insulator products produced by enterprises during the statistical reporting period is generally based on kgce/t said.

Note: The quality of qualified porcelain insulators includes the quality of the end fittings permanently fixed on the porcelain and the quality of the corresponding glue-mounted materials.

3.3 Net calorific value

Low calorific value net calorific value.

The total amount of heat emitted by a unit mass of fuel when it is completely burned is the calorific value after deducting the latent heat of vaporization of water vapor in the flue gas.

4.3 Advanced value of comprehensive energy consumption per unit product of porcelain insulators

The advanced value of comprehensive energy consumption per unit product of porcelain insulator is shown in Table 3.

4.4 Other

Cylinder head structure disc-shaped suspension porcelain insulators and inorganic bonded hollow porcelain insulators, the comprehensive energy consumption per unit limit value, access value and advanced The values are correspondingly increased by 20% compared to Table 1, Table 2 and Table 3.

According to the national regulations, the energy consumption limit for heating areas in winter is calculated at an increase of 3% per heating month.

In the production of multi-variety products, the specified value is calculated by weighting the actual output of the classified product in the total output.

5.1 Statistical scope

The statistical scope of the comprehensive energy consumption of porcelain insulators includes. raw material crushing, raw material mixing, raw material transportation, slurry preparation, slurry screening, and slurry In addition to iron, slurry filter press or spray drying, coarse mud smelting, stale mud, vacuum smelting and blank extrusion or blank pressing, blank drying, light blank Forming (compact and trimming), sand making, dry blank, glaze sanding, firing, cutting and grinding of porcelain, bonding of porcelain, porcelain and end The production process of assembly parts applying buffer layer, ceramic parts glued end assembly parts, product maintenance, finished product packaging, process transfer, etc., as well as all auxiliary and The energy consumed by the subsidiary production process.

5.2 Statistical methods

The energy consumption of the main production system shall be classified according to the actual measurement statistics in Table 1 to Table 3. The equipment and management of energy measuring instruments shall comply with GB 17167 Regulations. The energy consumption of the auxiliary production system and the auxiliary production system can be shared and counted. The output of qualified products is classified and counted according to product categories. can There should be no re-counting or under-counting in the statistics of consumption and production of qualified products.

5.3 Calculation method

The calculation of product comprehensive energy consumption and unit product comprehensive energy consumption shall comply with GB/T 2589-2008.

The comprehensive energy consumption of the product is calculated according to formula (1).

5.4 Conversion of standard coal

The various energy consumed should be converted into a unified standard coal based on the calorific value. The calorific value of the fuel is based on the average low of the fuel measured during the reporting period of the company Calorific value calculation. If the actual measurement is unconditional or the routine analysis is still difficult at present, the various energy sources given in Table A.1 of this standard can be converted into standard coal The coefficient is converted to standard coal. Other energy-consuming working fluids are converted into standard coal using the conversion coefficient given in Table A.2 of this standard.

6.1 Energy-saving basic management

Porcelain insulator manufacturers should reasonably configure and use energy measuring instruments according to their actual conditions and the classification statistics requirements of this standard.

And meet the requirements of GB 17167, establish and improve the energy monitoring, statistics, internal audit, assessment, supervision, rewards and punishment systems and conform to this standard According to the energy consumption statistics system, strengthen the controlled management of the whole process, determine and implement comprehensive energy consumption assessment indicators per unit of product.

6.2 Energy-saving technology and management

Porcelain insulator manufacturers should actively promote the use of new energy-saving technology, such as energy-saving raw material processing technology, energy-saving drying technology, high-speed Isothermal roasting technology, waste heat utilization technology, etc.

Newly built, renovated and expanded porcelain insulator production enterprises should reach economic operation scale, and the configured general energy-consuming equipment should reach the corresponding energy-consuming equipment.

The requirements of the energy-saving evaluation value in the efficiency standard.

Porcelain insulator manufacturers should make their general energy-consuming equipment meet the requirements of the economic operation standard of the corresponding energy-consuming equipment and reach the economic operation state.

Porcelain insulator manufacturers should take effective measures to ensure the normal, stable and continuous operation of the production system.
