Mark Kraftvärme is a Swedish biomass plant with 2 combustion lines.
Combustion system upgrade
Dublix Engineering carried out a major combustion system upgrade on one combustion in 2007 and 2008.
The actual combustion line is burning 4 t/h forest wood including low grade bark, producing 10 MW steam (32 bar/220 degC).
As a result of the optimization with an improoved grate operation, the combustion capacity was heavily increased (by 10-15%) and the biomass throughput has been increased accordingly.
