Before heating season 2009/10. PUC “Beogradske elektrane” burns up to 10.000 tons of coal per year. Besides high emissions of SO2, CO, NOx and particulates there is a serious problem of ground contamination with coal and ash during transport, handling and storage. This is another important reason for introduction biomass in coal fuelled boilers and thus further decreasing the consumption of coal and introduction of renewable.
