3 Terms and definitions
Terms and definitions determined by GB 175, GB/T 2589, GB/T 12723, GB/T
21372, and the following ones are applicable to this document.
3.1
Energy consumption per unit product of clinker
During the period of statistical report, the various energy consumed by energy
consumption units in the production of cement clinker, which is equivalent to
the energy consumed by 1 t of cement clinker.
3.2
Energy consumption per unit product of cement
During the period of statistical report, the various energy consumed by energy
consumption units in the production of cement, which is equivalent to the energy
consumed by 1 t of cement.
3.3
Fuel consumption per unit product of clinker
During the period of statistical report, the fuel quantity such as coal and diesel
consumed by energy consumption units in the production of cement clinker,
which is equivalent to the standard coal quantity consumed by 1 t of cement
clinker.
3.4
Electricity consumption per unit product of clinker
During the period of statistical report, the electricity consumed by energy
consumption units in the production of cement clinker, which is equivalent to
the electricity consumed by 1 t of cement clinker.
3.5
Electricity consumption per unit product of cement
6 Statistical range and calculation method
6.1 Statistical range
6.1.1 Statistical range of energy consumption per unit product of clinker
Within the scope of energy consumption management of cement clinker
product manufacturing enterprises, various energy sources consumed in the
main production process and auxiliary production process from the entry of raw
fuel into the production plant to the output of cement clinker, excluding the
energy consumed during the project construction period like infrastructure,
technological transformation. If coprocessing or alternative fuels are used, the
amount of energy consumed and the amount of alternative fuels shall be
counted separately. When the waste gas from the burning system is used for
power generation in a waste heat power station, the power generation of the
waste heat power station and the selfconsumption power of the waste heat
power station shall be counted. The calorific value of solid fuel shall be
determined in accordance with the requirements of GB/T 213 and GB/T 30727;
the calorific value of liquid fuel shall be determined in accordance with the
requirements of GB/T 384. The statistics of electricity consumption shall meet
the requirements of GB/T 27977.
6.1.2 Statistical range of energy consumption per unit product of cement
Within the scope of energy consumption management of cement product
manufacturing enterprises, various energy sources consumed in the main
production process and auxiliary production process from the entry of raw fuel
into the production plant to the delivery of cement products, excluding the
energy consumed during the project construction period like infrastructure,
technological transformation. If coprocessing or alternative fuels are used, the
amount of energy consumed and the amount of alternative fuels shall be
counted separately. When the waste gas from the burning system is used for
power generation in a waste heat power station, the power generation of the
waste heat power station and the selfconsumption power of the waste heat
power station shall be counted. The calorific value of solid fuel shall be
determined in accordance with the requirements of GB/T 213 and GB/T 30727;
the calorific value of liquid fuel shall be determined in accordance with the
requirements of GB/T 384. The statistics of power consumption shall meet the
requirements of GB/T 27977.
6.1.3 Statistical range of electricity consumption of the cement
preparation section
Within the scope of energy consumption management of cement product
manufacturing enterprises, the electricity consumed within the statistical range
Where:
WS – electricity consumption per unit product of cement, in kilowatthours per
ton (kWh/t);
PS – the total output of cement products that meets the requirements of GB/T
175 during the period of statistical report, in tons (t);
wS – the total electricity consumption within the statistical range of electricity
consumption of cement products, in kilowatthours (kW·h), which is
calculated according to Formula (7):
Where:
wg – the electricity consumption during the cement grinding and packaging
process within the period of statistical report, in kilowatthours (kWh);
Pshx – the consumption of clinker for the production of cement within the period
of statistical report, in tons (t);
wm – the electrical energy consumed by the pretreatment of admixture within
the period of statistical report, in kilowatthours (kWh);
wfm – the electrical energy consumed by the pretreatment of gypsum within the
period of statistical report, in kilowatthours (kWh);
wfz – the auxiliary production electricity consumption that shall be apportioned
within the period of statistical report, in kilowatthours (kW·h).
When the enterprise uses all purchased clinker to produce cement, Wsh in
Formula (7) is calculated as zero; when the enterprise purchases part of the
clinker to produce cement, Wsh in Formula (7) shall be the electricity
consumption per unit product of clinker of the enterprise.
6.2.5 Energy consumption per unit product of cement
The energy consumption per unit product of cement shall be calculated
according to Formula (8):
Where:
