CHP Plant Zvolen

Start up dates:planning: 2011; construction: 2011; operation/commissioning: 2011
Feedstocks of current use:forestry residues, waste wood, wood, wood chips
Electric capacity:45000 kW
Thermal capacity:312000 kW
Total Output:100000 MWh
Savings of CO2:80000 t/y
Incentive type:public grants
Positive experiences:9000 heated flats with entire biomass use. One motivation for the installation of the plant was to reduce emissions of SO2 resulting
from coal-combustion – biomass is a fuel free of sulphur. The forthcoming (2016)
emission-limits of 200 mg/m3 of SO2 will, however, not be met with the current plant design.
Additionally, this plant supports Slovak Republic in meeting her renewables requirements
and increasing the share of renewables in a relatively simple way by using
available and running fossil-based infrastructure.
Negative experiences:Due to the process, the ash from biomass-combustion is mixed with coal-based ash, so it
cannot be treated separately and has to be dumped in landfills. Other problems arise
from carbon-blacking of the heat-exchangers, the still needed optimization of secondaryair
vans, operational handling by the operators of the plant, and the adaptation of the
plant to the different qualities of the biomass-fuel.
