Division BAT 53 In order to reduce the consumption of thermal and electrical energy, BAT is to use a combination of the techniques given below.
United Kingdom
| Technique | Applicability | |
|---|---|---|
| a | Energy saving screening techniques (optimised rotor design, screens and screen operation) | Applicable to new mills or major refurbishments |
| b | Best practice refining with heat recovery from the refiners | |
| c | Optimised dewatering in the press section of paper machine/wide nip press | Not applicable to tissue paper and many speciality papers grades |
| d | Steam condensate recovery and use of efficient exhaust air heat recovery systems | Generally applicable |
| e | Reduction of direct use of steam by careful process integration using e.g. pinch analysis | |
| f | High efficient refiners | Applicable to new plants |
| g | Optimisation of the operating mode in existing refiners (e.g. reduction of ‘no load power requirements) | Generally applicable |
| h | Optimised pumping design, variable speed drive control for pumps, gearless drives | |
| i | Cutting edge refining technologies | |
| j | Steam box heating of the paper web to improve the drainage properties/dewatering capacity | Not applicable to tissue paper and many speciality papers grades |
| k | Optimised vacuum system (e.g. turbo fans instead of water ring pumps) | Generally applicable |
| l | Generation optimisation and distribution network maintenance | |
| m | Optimisation of heat recovery, air system, insulation | |
| n | Use of high efficient motors (EFF1) | |
| o | Preheating of shower water with a heat exchanger | |
| p | Use of waste heat for sludge drying or upgrading of dewatered biomass | |
| q | Heat recovery from axial blowers (if used) for the supply air of the drying hood | |
| r | Heat recovery of exhaust air from the Yankee hood with a trickling tower | |
| s | Heat recovery from the infrared exhaust hot air |
