BWE has been one of the pioneer in biomass combustion technologies due
to the demand of the Danish/Scandinavian market for such solution.
The drivers of the involvement of BWE in the biomass project are deriving
from different side all related to environmental concerns
Experience in biomass
Driver Technology Project
Availability of straw to
be disposed
Straw combustion Various
Ban of coal for large
combustion plant and
introduction of subsidy
for the use of biomass
Large biomass

• Originally commissioned on gas/oil in 2001
• Burners converted (2003):
• Gas/Oil => Gas/Oil/ Wood pellets
• The wood pellets are pulverized in traditional roller mills
• 3 of 4 burner levels (12 of 16 BWE burners) can burn 100% wood
(70% of heat input)
• The 4th level can only burn oil/gas
• The thermal input is up to 560 MJ/s on wood – equivalent to approx. 250 MWe resulting
from biomass
