# 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 56

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

In order to reduce thermal energy consumption, BAT is to use a combination of the following techniques:
Technique
Description
Applicability
a
Applying improved and optimised kiln systems and a smooth and stable kiln process by applying:
I.. process control optimisation
II.. heat recovery from flue-gases from kiln and coolers
Heat recovery from flue-gases by the preliminary heating of the magnesite can be used in order to reduce fuel energy use. Heat recovered from the kiln can be used for drying fuels, raw materials and some packaging materials
Process control optimisation is applicable to all kiln types used in the magnesia industry.
b
Using fuels with characteristics which have a positive influence on thermal energy consumption
The characteristics of fuels, e.g. high calorific value and low moisture content have a positive effect on the thermal energy consumption
Generally applicable subject to availability of the fuels, the type of kilns used, the desired product qualities and the technical possibilities of injecting the fuels into the kiln.
c
Limiting excess air
The excess oxygen level to obtain the required quality of the products and for optimal combustion is usually in practice about 1 – 3 %
Generally applicable
