Division 13.1 Energy efficiency
United Kingdom
BAT 35. In order to increase the energy efficiency, BAT is to use an appropriate combination of the techniques specified in BAT 6 and one or a combination of the techniques given below.
| Technique | Description | Applicability | |
|---|---|---|---|
| (a) | Pressing of beet pulp | The beet pulp is pressed to a dry matter content of typically 25-32 wt-%. | Generally applicable. |
| (b) | Indirect drying (steam drying) of beet pulp | Drying of beet pulp by the use of superheated steam. | May not be applicable to existing plants due to the need for a complete reconstruction of the energy facilities. |
| (c) | Solar drying of beet pulp | Use of solar energy to dry beet pulp. | May not be applicable due to local climatic conditions and/or lack of space. |
| (d) | Recycling of hot gases | Recycling of hot gases (e.g. waste gases from the dryer, boiler or combined heat and power plant). | Generally applicable. |
| (e) | Low-temperature (pre)drying of beet pulp | Direct (pre)drying of beet pulp using drying gas, e.g. air or hot gas. | |
