# 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 7

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

In order to reduce/minimise thermal energy consumption, BAT is to use a combination of the following techniques:
Technique
Applicability
a
Applying improved and optimised kiln systems and a smooth and stable kiln process, operating close to the process parameter set points by applying:
I.. process control optimisation, including computer-based automatic control systems
II.. modern, gravimetric solid fuel feed systems
III.. preheating and precalcination to the extent possible, considering the existing kiln system configuration
Generally applicable. For existing kilns, the applicability of preheating and precalcination is subject to the kiln system configuration
b
Recovering excess heat from kilns, especially from their cooling zone. In particular, the kiln excess heat from the cooling zone (hot air) or from the preheater can be used for drying raw materials
Generally applicable in the cement industry.
Recovery of excess heat from the cooling zone is applicable when grate coolers are used.
Limited recovery efficiency can be achieved on rotary coolers
c
Applying the appropriate number of cyclone stages related to the characteristics and properties of raw material and fuels used
Cyclone preheater stages are applicable to new plants and major upgrades.
d
Using fuels with characteristics which have a positive influence on the thermal energy consumption
The technique is generally applicable to the cement kilns subject to fuel availability and for existing kilns subject to the technical possibilities of injecting the fuel into the kiln
e
When replacing conventional fuels by waste fuels, using optimised and suitable cement kiln systems for burning wastes
Generally applicable to all cement kiln types
f
Minimising bypass flows
Generally applicable to the cement industry
