Division BAT 32 In order to increase the efficiency of power generation, BAT is to apply a combination of the techniques given below.
United Kingdom
| Technique | |
|---|---|
| a | High black liquor dry solid content (increases boiler efficiency, steam generation and thus electricity generation) |
| b | High recovery boiler pressure and temperature; in new recovery boilers the pressure can be at least 100 bars and the temperature 510 °C |
| c | Outlet steam pressure in the back-pressure turbine as low as technically feasible |
| d | Condensing turbine for power production from excess steam |
| e | High turbine efficiency |
| f | Preheating feedwater to a temperature close to the boiling temperature |
| g | Preheating the combustion air and fuel charged to the boilers |
