foreword
This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents"
drafted:
This document replaces GB/T 26281-2010 "Calculation Method for Thermal Balance, Thermal Efficiency and Comprehensive Energy Consumption of Cement Rotary Kiln", and
Compared with GB/T 26281-2010, in addition to structural adjustment and editorial changes, the main technical changes are as follows:
a) Changed the terms and definitions of the comprehensive energy consumption of cement clinker burning and the heat consumption of clinker burning, and increased the heat utilization rate of the burning system and the cement clinker burning:
Definitions of terms of comprehensive fuel consumption for fuel burning (see 3:1~3:4, 3:1~3:3 of the:2010 edition);
b) Changed the material balance range (see 5:1:1, 5:1:2, 5:1:1, 5:1:2 of the:2010 edition);
c) Changed the calculation of fuel consumption in material balance (see 5:1:2:1, 5:1:2:1 of the:2010 edition);
d) Changed the calculation of the heat of fuel combustion and the heat of clinker formation in the heat balance calculation, and revised the heat of pulverized coal entering the kiln in the calculation of the heat of fuel combustion
The requirements for the determination of the value of the clinker are added, and the calculation of the heat generated by the clinker and the waste heat of the cooling machine when the alternative raw materials such as carbide slag are added is added:
calculation method (see 5:2:2:1, 5:2:3:1, 5:2:3:8, 5:2:2:1, 5:2:3:1 of the:2010 edition);
e) Changed the calculation of the thermal efficiency of cement rotary kiln, and added the calculation of the thermal utilization rate of the firing system and the fuel substitution rate (see 5:3,:2010
5:2:4 of the year edition);
f) Changed the calculation content of the heat expenditure item in the heat balance calculation of the cooler, and added the calculation of the waste heat of the cooler to be taken out by the wind (see 6:1:2,
2010 version 6:1:2);
g) Changed the calculation range and method of comprehensive energy consumption of cement clinker firing (see 7:2:1, 6:2 of the:2010 edition), added
Calculation of the comprehensive fuel consumption for burning the fuel (see 7:2:2):
