# 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 30: In order to reduce dust and particulate-bound metal emissions to air from the combustion of HFO and/or gas oil in boilers, 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.
Multicyclones
See description in Section 8.5.
Multicyclones can be used in combination with other dedusting techniques
d.
Dry or semi-dry FGD system
See descriptions in Section 8.5.
The technique is mainly used for SOX, HCl and/or HF control
e.
Wet flue-gas desulphurisation (wet FGD)
See description in Section 8.5.
The technique is mainly used for SOX, HCl and/or HF control
See applicability in BAT 29
f.
Fuel choice
See description in Section 8.5
Applicable within the constraints associated with the availability of different types of fuel, which may be impacted by the energy policy of the Member State
Table 16
BAT-associated emission levels (BAT-AELs) for dust emissions to air from the combustion of HFO and/or gas oil in boilers
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 25 mg/Nm3 for plants put into operation no later than 7 January 2014.
The higher end of the BAT-AEL range is 15 mg/Nm3 for plants put into operation no later than 7 January 2014.
