Foreword
This document was drafted in accordance with the rules given in GB/T 1.1-2020,
"Directives for standardization - Part 1.Rules for the structure and drafting of
standardizing documents".
This document replaces GB 16780-2012 "The norm of energy consumption per
unit products of cement"; compared with GB 16780-2012, the major technical
changes are as follows.
-- Change the terms and definitions of energy consumption related indexes
(see 3.1~3.5; 3.1~3.8 of version 2012);
-- Add the norm grade of energy consumption (see Chapter 4);
-- Delete the advanced value of energy consumption (see 4.3 of version
2012);
-- INCLUDE the norm of electricity consumption of the cement preparation
section in the step-by-step energy consumption norm of the cement
enterprise in Appendix B IN the text; delete Appendix B (see 4.3; Appendix
B of version 2012);
-- Change the correction coefficients of influencing factors in the calculation
of the norm of energy consumption per unit product (see 5.3; 5.3.1.5 and
5.3.4.2 of version 2012);
-- Change the calculation formula of the norm of energy consumption index
(see 6.2; 5.3 of version 2012);
-- Delete the energy-saving management and measures (see Chapter 6 of
version 2012);
-- Delete the calculation method for the average 28d compressive strength
of clinker (see Appendix A of version 2012).

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.
4 Energy consumption norm grade
4.1 See Table 1 for the norm grade of comprehensive energy consumption per
unit product of cement, where grade 1 has the lowest energy consumption.
4.2 See Table 2 for the norm grade of energy consumption, electricity
consumption and fuel consumption per unit product of clinker, where grade 1
has the lowest energy consumption.
4.3 See Table 3 for the norm grade of electricity consumption of the cement
preparation section, where grade 1 has the lowest energy consumption.
5 Technical requirements
5.1 For existing enterprises that produce cement and cement clinker products,
the limit value of energy consumption per unit product shall meet the
requirements of grade 3 in Table 1 ~ Table 3;
5.2 For newly-built, rebuilt and expanded enterprises that produce cement and
cement clinker products, the access value of energy consumption per unit
product shall meet the requirements of grade 2 in Table 1 ~ Table 3;
5.3 When the altitude of the existing enterprise plant that produces cement and
cement clinker products is greater than 1 500 m,
5.4 When the proportion of clinker in cement products is higher or lower than
75%, for each increase or decrease of 1%, the grade-1, grade-2, and grade-3
norm values of energy consumption per unit product of cement shall be
increased or decreased by 1.10 kgce/t, 1.15 kgce/t and 1.20 kgce/t.
