3.2 The power consumption index of the number of units is shown in Table 2. Table 2
Average electrical cabinet grade index of composite extrusion products with ·T grade
Note: The power consumption index of diamond carbon sheet petrochemical is twice the index in the table. 4 Calculation of average energy consumption of qualified products per unit during the statistical period
4.1 Using gas and solid fuel, the average energy consumption of qualified products is calculated according to formula (1):
In the formula: - Average energy consumption of roasted composite products, kJkg qualified products;
Gas fuel consumption under standard conditions during the statistical period, II\; or weekly fuel consumption, etc.
Average calorific value of gas fuel under standard conditions during the statistical period, 3m: or weekly fuel application base lower calorific value, kj/kg:
Average qualified rate of roasted products during the statistical period, %: G:
Weight of solid products during the statistical period, kg. 4.2 The average power consumption of qualified products of intermittent graphite furnace is calculated according to formula (2): R
Where: h. -Graphitization: Average power consumption of qualified products, kW·h/kg qualified products; -Power consumption of the furnace during the statistical period, kw-h:
Average qualified rate of products discharged from the furnace during the statistical period, s:
Weight of products discharged from the furnace during the statistical period, kg. 5Energy consumption measurement
Energy consumption must be calculated by volume,
5.1Coal: Measured by weighing instrument,
5.2Gas fuel: Measured by flow meter and converted into volume under standard soft conditions. 5.3Power consumption of graphite furnace is calculated by high voltage side of transformer. 5.4Relay and wheel are calculated monthly. For example, the flame density and the wall protection of the interspherical ball are calculated according to the density (furnace" time. 6 Fuel calorific value

6.1 Coal: The data provided by the coal supply unit in each period, or the data of each batch of coal entering the factory in each period (monthly 212 certificate 1 industry analysis, using GB/T 2589.
6.2 Gas fuel: The average low calorific value provided by the supply unit or department during the statistical period shall be used. The low calorific value of the dry gas fuel supplied by the fee shall be converted into the low calorific value of the gas fuel according to formula (3): f
Wherein: 65w

Low calorific value of wet gas fuel under standard conditions, k/m: Low calorific value of wet gas fuel under standard conditions, kJ/m: Specific humidity value of dry gas fuel under standard conditions (including wet disk), m dry gas fuel 7 honey furnace test
Special and first-class dense furnaces must be tested individually, and second-class and third-class kilns are allowed to be tested as dense furnace groups. The total unit energy gross index is the same as the index of the ancestral dense furnace in Table 1.
