# Commission Implementing Decision of 26 March 2013 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for the production of cement, lime and magnesium oxide (notified under document C(2013) 1728) (Text with EEA relevance) (2013/163/EU), Division 45

Extent: E+W+S+N.I.

In order to reduce the emissions of NOX from the flue-gases of kiln firing processes, BAT is to use one or a combination of the following techniques:
A description of the techniques is provided in Section 1.6.2
Technique
Applicability
a
Primary techniques
I.
Appropriate fuel selection along with limitation of nitrogen content in the fuel
Generally applicable in the lime industry subject to fuel availability which may be impacted by the energy policy of the Member State and to the technical possibility to feed a certain type of fuel into the selected kiln
II.
Process optimisation including flame shaping and temperature profile
Optimisation of process and process control can be applied in lime manufacturing but is subject to the final product quality
III.
Burner design (low NOX burner)
Low NOX burners are applicable to rotary kilns and to annular shaft kilns presenting conditions of high primary air. PFRKs and other shaft kilns have flameless combustion, thus rendering low NOX burners not applicable to this kiln type
IV.
Air staging
Not applicable to shaft kilns.
Applicable only to PRK but not when hard burned lime is produced. The applicability may be limited by constraints imposed by the type of final product, due to possible overheating in some areas of the kiln and consequent deterioration of the refractory lining
b
SNCR
Applicable to Lepol rotary kilns. See also BAT 46
