4 Calculation Methods
4.1 General Stipulations
4.1.1 Range of water intake
The range of water intake refers to the amount of water that enterprises extract from various regular water resources, including surface water (calculated by the water supplied by water purification plants), groundwater, city and town water supply engineering, and other water or water products (such as vapor, hot water and geothermal water, etc.) that enterprises purchase from the market.
4.1.2 Range of water intake supply
The range of sintering water intake supply includes primary production (including fuel crushing, flux crushing, ingredients, mixture, pelletizing, sintering, cooling, screening, and storage and transportation of finished products), auxiliary production (including water-circulating station, air-compressing station and sewage treatment station, etc.) and subsidiary production (including office, afforestation, factory canteen, bathroom and washroom, etc.).
The range of pelletizing water intake supply includes primary production (reception and storage of concentrates, concentrate drying, pulverized coal preparation, ingredients, mixture, pelletizing, drying, pre-heating, roasting, cooling, and storage and transportation of finished products), auxiliary production (water-circulating station and air-compressing station, etc.) and subsidiary production (including office, afforestation, factory canteen, bathroom and washroom, etc.).
The norm of water intake shall be respectively formulated in terms of sintering waster heat power generation, sintering flue gas desulfurization and pellet flue gas desulfurization.
4.1.3 Measurement of water intake
Water intake shall be measured in accordance with enterprises’ Level-1 measurement scale.
4.2 Water Intake of Finished Ore (per ton)
Water intake of finished ore (per ton) shall be calculated in accordance with Formula (1).
Where.
Vui---Water intake of finished ore (per ton), expressed in (m3/t);
Vi---Enterprises’ water intake of manufacturing finished ore within a certain measuring time, expressed in (m3);
