Division BAT 7 In order to increase the energy efficiency, BAT is to optimise the operation of the combustion plant by monitoring and controlling key combustion parameters (e.g. O2, CO, NOx) and applying one or a combination of the techniques given below.
United Kingdom
| Technique | Applicability | |
|---|---|---|
| a | Dewater wood sludge before it is used as a fuel | Generally applicable |
| b | Recover heat from hot waste gases in wet abatement systems using a heat exchanger | Applicable to plants with a wet abatement system and when the recovered energy can be used |
| c | Recirculate hot waste gases from different processes to the combustion plant or to preheat hot gases for the dryer | Applicability may be restricted for indirectly heated dryers, fibre dryers or where the combustion plant configuration does not allow controlled air addition |
