# Commission Implementing Decision of 26 September 2014 establishing the best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for the production of pulp, paper and board (notified under document C(2014) 6750) (Text with EEA relevance) (2014/687/EU), Division BAT 31: In order to reduce thermal energy consumption (steam), maximise the benefit of energy carriers used, and to reduce the consumption of electricity, BAT is to apply a combination of the techniques given below.

Extent: E+W+S+N.I.

Technique
a
High dry solid content of bark, by use of efficient presses or drying
b
High efficiency steam boilers, e.g. low flue-gas temperatures
c
Effective secondary heating systems
d
Closing water systems, including bleach plant
e
High pulp concentration (middle or high consistency technique)
f
High efficiency evaporation plant
g
Recovery of heat from dissolving tanks e.g. by vent scrubbers
h
Recovery and use of the low temperature streams from effluents and other waste heat sources to heat buildings, boiler feedwater and process water
i
Appropriate use of secondary heat and secondary condensate
j
Monitoring and control of processes, using advanced control systems
k
Optimise integrated heat exchanger network
l
Heat recovery from the flue-gas from the recovery boiler between the ESP and the fan
m
Ensuring as high a pulp consistency as possible in screening and cleaning
n
Use of speed control of various large motors
o
Use of efficient vacuum pumps
p
Proper sizing of pipes, pumps and fans
q
Optimised tank levels
