Division BAT 38 In order to reduce thermal energy consumption (steam), maximise the benefit of the energy carriers used and to reduce the consumption of electricity, BAT is to use a combination of the techniques given below.
United Kingdom
| Technique | |
|---|---|
| a | High dry solids content of bark, by use of efficient presses or drying |
| b | High efficiency steam boilers, e.g. low exhaust-gas temperatures |
| c | Effective secondary heating system |
| d | Closing water systems, including bleach plant |
| e | High pulp concentration (middle or high consistency techniques) |
| f | Recovery and use of the low temperature streams from effluents and other waste heat sources to heat buildings, boiler feedwater and process water |
| g | Appropriate use of secondary heat and secondary condensate |
| h | Monitoring and control of processes, using advanced control systems |
| i | Optimise integrated heat exchanger network |
| j | Ensuring as high pulp consistency as possible in screening and cleaning |
| k | Optimised tank levels |
