Division 12.3 Techniques to reduce emissions to air from combustion
United Kingdom
| Technique | Description |
|---|---|
| Choice of (support) fuel | The use of fuel (including support/auxiliary fuel) with a low content of potential pollution-generating compounds (e.g. lower sulphur, ash, nitrogen, mercury, fluorine or chlorine content in the fuel). |
| Low-NOX burner (LNB) and ultra-low-NOX burner (ULNB) | The technique is based on the principles of reducing peak flame temperatures, delaying but completing the combustion and increasing the heat transfer (increased emissivity of the flame). It may be associated with a modified design of the furnace combustion chamber. The design of ultra-low-NOX burners (ULNB) includes (air/)fuel staging and exhaust/flue-gas recirculation. |
