3 Terms and definitions
The terms and definitions as defined in GB/T 12723 as well as the following terms and definitions apply to this document.
3.1
Comprehensive energy consumption of cement products
During the reporting period, the total energy consumption of a certain type of cement product in the entire product production process from the entry of raw materials into the plant and the metering of energy into the process until the finished product exit-warehouse.
3.2
The comprehensive energy consumption per unit product throughput
of cement products
During the reporting period, the comprehensive energy consumption of a
certain type of cement product expressed in terms of the unit (per cubic meter of concrete) qualified product throughput.
3.3
The coal consumption per unit throughput of cement products
During the reporting period, the steam (or steam-producing fuel)
consumption of a certain type of cement product expressed as the unit (per cubic meter) of qualified product throughput.
6.1.1.2 The calorific value of various energy sources shall be converted into a unified standard coal. The calorific value of various energy sources is based on the caloric value measured by the enterprise during the reporting period. If there are no actual measurement conditions, it shall use the reference coefficients for converting various standard energy sources as given in GB/T 2589.
6.1.1.3 The statistics and accounting of energy consumption shall include the above-mentioned various production links; it shall not be repeated or missed. 6.1.2 Classification
6.1.2.1 Precast concrete pile
The energy consumption of such products shall be subject to statistics in the entire production process of product from the entry of raw materials [cement, admixtures (fine sand, fine slag powder, silica fume, fly ash, etc.), aggregates, admixtures, PC steel rods, end plates, pile ferrules, steel bars (hot-rolled wire rod, cold-drawn wire, etc.) etc.] into factory and the including of energy into the procedure through metering, to the exit-warehouse of metered finished product. 6.1.2.2 Circular concrete pole
The energy consumption of such products shall be subject to statistics in the entire production process of product from the entry of raw materials [cement, admixtures (fine sand, silica fume, etc.), aggregates, additives, flanges, steel bars (pre-tensioned bars, hot-rolled wire rod, cold-drawn wire, etc.) etc.] into factory and the including of energy into the procedure through metering, to the exit-warehouse of metered finished product.
6.1.2.3 Concrete and reinforced concrete sewer pipes
The energy consumption of such products shall be subject to statistics in the entire production process of product from the entry of raw materials [cement, aggregates, additives, steel bars (hot-rolled wire rod, cold-drawn wire, etc.) etc.] into factory and the including of energy into the procedure through metering, to the exit-warehouse of metered finished product.
6.1.2.4 Prestressed steel tube concrete pipe
The energy consumption of such products shall be subject to statistics in the entire production process of product from the entry of raw materials [cement, aggregate, admixtures, steel plates (including socket rings and plug rings), steel bars (prestressed steel bars, hot-rolled wire rods, cold-drawn wires, etc.), etc.] into factory and the including of energy into the procedure through metering, to the exit-warehouse of metered finished product.
6.1.2.5 Aerated concrete
Where:
E - Comprehensive energy consumption of a certain type of cement product throughput during the reporting period, in kilograms of standard coal (kgce); ei - The physical quantity of the i-th energy consumed by a certain type of cement product during the reporting period, in kilograms (kg);
??i - The converted standard coal coefficient of the i-th energy source; n - Number of energy types consumed.
6.3.3 Comprehensive energy consumption per unit throughput of cement
product
The comprehensive energy consumption per unit throughput of cement product is calculated according to formula (2), among which the coal consumption per unit of cement product throughput in cold regions shall be corrected according to the calculation method of 6.3.4.
Where:
Eg - The comprehensive energy consumption per unit throughput of a certain type of cement product during the reporting period (converted into energy consumption per cubic meter, expressed in the form of standard coal
consumption), in kilogram standard coal per cubic meter (kgce/m3);
G - Throughput of qualified products of a certain type of cement products during the reporting period (converted to cubic meters), in cubic meters (m3). 6.3.4 Correction of coal consumption per unit throughput of cement
products in cold regions
6.3.4.1 The corrected value of coal consumption per unit throughput of cement products in cold regions in winter is determined according to formula (3): Where:
E'gM - Corrected value of coal consumption per unit throughput of cement products in cold regions in winter, in kilogram standard coal per cubic meter (kgce/m3);
E'M - The actual coal consumption value of a certain type of cement product in winter in cold regions, in kilogram (kg);
