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

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 co-processing 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 self-consumption 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 co-processing 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 self-consumption 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 kilowatt-hours 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 kilowatt-hours (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 kilowatt-hours (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 kilowatt-hours (kWh);
wfm ?€? the electrical energy consumed by the pretreatment of gypsum within the period of statistical report, in kilowatt-hours (kWh);
wfz ?€? the auxiliary production electricity consumption that shall be apportioned within the period of statistical report, in kilowatt-hours (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):
