Division BAT 53 In order to prevent or reduce NOX emissions to air from the combustion of gaseous and/or liquid fuels on offshore platforms, BAT is to use one or a combination of the techniques given below.
United Kingdom
| Technique | Description | Applicability | |
|---|---|---|---|
| a. | Advanced control system | See descriptions in Section 8.3 | The applicability to old combustion plants may be constrained by the need to retrofit the combustion system and/or control command system |
| b. | Dry low-NOX burners (DLN) | Applicable to new gas turbines (standard equipment) within the constraints associated with fuel quality variations. The applicability may be limited for existing gas turbines by: availability of a retrofit package (for low-load operation), complexity of the platform organisation and space availability | |
| c. | Lean-burn concept | Only applicable to new gas-fired engines | |
| d. | Low-NOX burners (LNB) | Only applicable to boilers | |
