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.
United Kingdom
| 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 |

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. | ||||
| Combustion plant total rated thermal input(MWth) | BAT-AELs for dust (mg/Nm3) | |||
