# Commission Implementing Decision (EU) 2017/1442 of 31 July 2017 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for large combustion plants (notified under document C(2017) 5225) (Text with EEA relevance), Division BAT 22: In order to reduce dust and particulate-bound metal emissions to air from the combustion of coal and/or lignite, BAT is to use one or a combination of the techniques given below.

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

Technique
Description
Applicability
a.
Electrostatic precipitator (ESP)
See description in Section 8.5
Generally applicable
b.
Bag filter
c.
Boiler sorbent injection
(in-furnace or in-bed)
See descriptions in Section 8.5.
The techniques are mainly used for SOX, HCl and/or HF control
d.
Dry or semi-dry FGD system
e.
Wet flue-gas desulphurisation (wet FGD)
See applicability in BAT 21
Table 6
BAT-associated emission levels (BAT-AELs) for dust emissions to air from the combustion of coal and/or lignite
These BAT-AELs do not apply to plants operated < 1 500 h/yr.
For plants operated < 500 h/yr, these levels are indicative.
The higher end of the BAT-AEL range is 28 mg/Nm3 for plants put into operation no later than 7 January 2014.
The higher end of the BAT-AEL range is 25 mg/Nm3 for plants put into operation no later than 7 January 2014.
The higher end of the BAT-AEL range is 12 mg/Nm3 for plants put into operation no later than 7 January 2014.
The higher end of the BAT-AEL range is 20 mg/Nm3 for plants put into operation no later than 7 January 2014.
The higher end of the BAT-AEL range is 14 mg/Nm3 for plants put into operation no later than 7 January 2014.
