Scope
GB/T 37249-2018 is the English-translated version of 硅酸盐水泥熟料生产中二氧化硫排放量计算方法.
GB/T 37249-2018 gives a method for calculating how much sulphur dioxide is emitted in the production of Portland cement clinker.
It defines the SO2 emission per unit of clinker, draws the statistical boundary around three stages - raw material preparation, clinker burning including pulverized coal preparation, and co-processing of waste - and sets the statistical period.
It then covers the calculation items and data, the calculation of emissions per unit of clinker and of total emissions from clinker production, relying on chemical analyses of cement, coal and limestone and on flue gas sampling.
It applies to clinker production using calcium-based desulfurization, and can also serve as a basis for process design and production management of clinker lines. It was issued on 28 December 2018 and has applied since 1 November 2019.

Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
1 Scope
This standard specifies the terms and definitions, statistical boundaries and statistical periods for the calculation of sulfur dioxide emissions in the production of Portland cement clinker.
Calculation project and calculation data, calculation of sulfur dioxide emissions per clinker, and calculation of sulfur dioxide emissions in the production of Portland cement clinker Announced.
This standard is applicable to the calculation of sulfur dioxide emissions in the production of Portland cement clinker using calcium desulfurization, and also as cement clinker production.
The basis of line process design, production management and so on.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1 Unit clinker sulfur dioxide emissions
During the statistical period, the sulfur dioxide emissions generated by the production unit clinker.
4 Statistical boundaries and statistical periods
4.1 Statistical boundaries
When calculating the sulfur dioxide emissions per clinker, the statistical boundary is divided into three parts according to the production process of Portland cement clinker. as follows.
a) Raw material preparation. from the raw material into the production plant area, to the production process before the raw material enters the kiln, including crushing, grinding and conveying;
b) Clinker burning. from the raw material into the kiln, to the clinker into the clinker storage (including the top dust collection equipment) production process, including pulverized coal preparation system;
c) Collaborative disposal of waste. from waste into the production plant, to the production process where the waste enters the kiln incineration process.
