d) Increase the energy consumption limit level of graphitized cathode carbon blocks for aluminum electrolysis (see 4.3);
e) Increase the energy consumption limit level of cathode paste for aluminum electrolysis (see 4.4);
f) Change the statistical scope and calculation method of energy consumption of prebaked anode products for aluminum electrolysis (see 6.1, Chapter 5 of GB 25325-2014);
g) The statistical scope and calculation method of energy consumption of graphite cathode carbon block products for aluminum electrolysis have been changed (see 6.2, Chapter 25324-2014 of GB 25324-2014
Chapter 5);
h) Added the statistical scope and calculation method of energy consumption of graphitized cathode carbon block products for aluminum electrolysis (see 6.3);
i) Added the statistical scope and calculation method of energy consumption of cathode paste products for aluminum electrolysis (see 6.4);
j) Changed the current standard coal conversion coefficient of commonly used energy types and major energy-consuming working fluids (see 6.5).

4 Energy consumption quota levels
4.1 See Table 1 for the energy consumption limit levels per unit product of prebaked anodes for aluminum electrolysis, among which level 1 has the lowest energy consumption.
Table 1 Energy consumption limit level per unit product of prebaked anodes for aluminum electrolysis
The unit is kilogram standard coal per ton
index
energy consumption quota level
Level 1 Level 2 Level 3
Calcination process unit product comprehensive energy consumption ≤190 ≤210 ≤250
Comprehensive energy consumption per unit product in molding process ≤7 ≤10 ≤20
Comprehensive energy consumption per unit product in roasting process ≤170 ≤180 ≤230
Comprehensive energy consumption per unit product in the assembly process ≤9 ≤11 ≤15
Enterprises with only one process shall be evaluated according to the energy consumption limit level of the unit product of the corresponding process;
The combined value of the consumption quota level will be summed up and comprehensively assessed.
