Enter Kiln Fuel Consumption
Line101 to line123 are used to report those kiln fuels fed directly to the kiln or calciner of a kiln system (excluding drying of raw materials and fuels).
Whereas the fuels used for drying or processing of raw materials for the production of clinker and the preparation of other kiln fuels are reported separately (but also as kiln fuels) in line124 to line126a.
It is usual in cement plants that many types of fuels are used in kiln operations, e.g. coal, different types of fossil fuels, alternative fuels, biomass fuels, etc.
The consumption of each fuel type has to be determined at plant level in tonnes per year [t/yr]. Note that natural gas consumption should be reported in units of 1000 normal cubic meters per year [1000 Nm3/yr]. For example, if your consumption of natural gas in the kiln system was 27000 Nm3 in a certain year of reporting, enter the value of 27 in line106.
If you are using other kinds of fuels which are not covered by a certain category in a section, you are asked to report these fuel types in the lines which indicate "other" types of fuel. In addition to the amount of fuel consumption, the corresponding Fuel Parameters of the lower heating value (LHV
Lower heat value), the emission factor (EFEmission factor) for Mixed fuelsTerm used in this Guidance Document for referring to fuels that are a mix of
biomass and fossil fuel, i.e. fuel with a certain biogenic carbon content. and also the biogenic carbon content (Cbio/TC) should be determined.
For an overview of the fuel types used in the Plant sheet and their reporting parameters, please see Fuel Categories and Parameters for Reporting Fuel Energy Use and CO2 Emissions.
For the fuel "coal" for instance, input is needed in the following lines:
- t/yr of coal that is used as kiln-fuel (not for drying!): line102
- t/yr of coal that is used for the drying of raw materials and fuels only: line124a
- Lower Heating Value (LHVLower heat value) of coal in GJ/t: line132
- CO2 emission factors in GJ/t for coal: line186 (default value given)
The kiln fuel consumption is summarised as energy use in terajoules per year [TJ/yr] in line025 to line028.
Further evaluations of energy use and CO2 emissions from fuels are provided in the KPI section.
Please also see the Protocol Guidance Document for further guidance on the reporting of fuel energy use and CO2 emissions (Chapters 3.5, 3.6, 3.7 and 5).
