GB 21343-2015Norm of Energy Consumption per Unit Products of Calcium Carbide (English PDF)

3.1 Comprehensive energy consumption of calcium carbide

In the report period, the total amount of various energy consumed actually in the

production process of calcium carbide product.

room, lounge, locker room, bathhouse, as well as the devices for central

control analysis, product inspection, maintenance section etc.

5.1.2 The comprehensive energy consumption shall deduct the output of energy; the

following energy transferring externally beyond the production area of calcium carbide,

such as closed furnace gas, steam, nitrogen, compressed air and waste heat etc. shall

be calculated as the output of energy.

5.1.3 The comprehensive energy consumption of calcium carbide shall specially

include the following items.

a) The electricity consumption includes the one consumed in the production area

like furnace electricity consumption, power electricity consumption, lighting

electricity consumption, dust-removing facilities electricity consumption etc.;

b) The carbon raw materials consumed for the production of calcium carbide

include coke, blue carbon, petroleum coke, blind coal, other carbon as the

reducing agent etc. The calculation shall begin from the fist working process

entering into the production area; when calculating, deducting the moisture

within the carbon;

c) The fuel consumed by dry carbon materials, and its calorific value and

calculation method are the same as b). If using calcium carbide to produce the

waste heat dry carbon materials, its waste heat shall not calculate the fuel

consumption;

d) The energy-consumed medium that is suppled outside of the production area,

such as cooling water (soft water, desalted water), oxygen, nitrogen,

compressed air etc.; their calorific values shall be calculated as the specified

equivalent ones.

5.1.4 The energy consumption quantity and loss quantity in auxiliary and ancillary

production systems shall be distributed to the product.

5.1.5 The calorific values of various energies shall be converted into the uniform

measurement unit of standard coal per kilogram (kgce). The calorific values of various

energies shall be subject to the actually-measured values within the report period of

the enterprise; if there is no measured condition, convert the calorific values as per the

reference coefficients of various energies converting into the standard coal given in

Appendix A and B.

5.2 Calculation method

5.2.1 The comprehensive energy consumption of calcium carbide (E) shall be

calculated as per Formula (1).

The converted standard production quantity indicates convert the actual production

quantity of calcium carbide before the furnace into the production quantity with gas

evolution of 300L/kg as per the actual gas evolution.

The gas evolution of calcium carbide shall be measured as per the provisions of GB

10665.

5.2.3 The comprehensive energy consumption per unit product (Ecd) shall be

calculated as per the Formula (3).

Where.

Ecd – comprehensive energy consumption per unit product of calcium carbide, in tec/t.

5.2.4 The furnace electricity consumption per unit product of calcium carbide (Ed)

shall be calculated as per the Formula (4).

Where.

Ed – furnace electricity consumption per unit product of calcium carbide, in kW-h/t;

Qcd – furnace electricity consumed during the production process of calcium carbide,

in kW-h.

6.1 The enterprise shall regularly evaluate the comprehensive energy consumption

of calcium carbide, and furnace electricity consumption; distribute these evaluation

indicators to the grassroot department, and establish the responsibility system to use

energy.

6.2 The enterprise shall establish the energy consumption statistics system as per

the requirements; establish the documents on energy consumption test data, energy

consumption statistics, evaluation results etc.; carry out the controlled management

against the document.

6.3 The enterprise shall be equipped with the energy measurement instrument as

per the requirements of GB 17167; and establish the energy measurement

management system.
