Division BAT 6 In order to reduce fuel and energy consumption in pulp and paper mills, BAT is to use technique (a) and a combination of the other techniques given below.
United Kingdom
| Technique | Applicability | |
|---|---|---|
| a | Use an energy management system that includes all of the following features:
| Generally applicable |
| b | Recover energy by incinerating those wastes and residues from the production of pulp and paper that have high organic content and calorific value, taking into account BAT 12 | Only applicable if the recycling or reuse of wastes and residues from the production of pulp and paper with a high organic content and high calorific value is not possible |
| c | Cover the steam and power demand of the production processes as far as possible by the cogeneration of heat and power (CHP) | Applicable for all new plants and for major refurbishments of the energy plant. Applicability in existing plants may be limited due to the mill layout and available space |
| d | Use excess heat for the drying of biomass and sludge, to heat boiler feedwater and process water, to heat buildings, etc. | Applicability of this technique may be limited in cases where the heat sources and locations are far apart |
| e | Use thermo compressors | Applicable to both new and existing plants for all grades of paper and for coating machines, as long as medium pressure steam is available |
| f | Insulate steam and condensate pipe fittings | Generally applicable |
| g | Use energy efficient vacuum systems for dewatering | |
| h | Use high efficiency electrical motors, pumps and agitators | |
| i | Use frequency inverters for fans, compressors and pumps | |
| j | Match steam pressure levels with actual pressure needs |
