ABSTRACT
The Romanian Government adopted and implemented the regulations on large
combustion plants, which promotes the replacement of current technologies for
producing energy with clean technology for coal combustion in order to reduce SOx, NOx and dust emissions, but the CO2 emissions still remain at the same level. Cofiring of coal and biomass is considered as one of the main targets for the EU’s renewable energy goals. Currently, the Romanian large power plants use only fossil fuels to generate electricity. Although the coal-fired power plants are not designed to process and burn huge amounts of biomass, the paper presents a technical solution to decrease the CO2 emissions in large coal fired power plants, by co-firing coal with biomass. The paper focuses on the co-firing of coal and miscanthus giganteus, which is considered an additional and renewable fuel, with natural CO2 capture within the energy crops planted on historic mining waste dumps. This approach could be considered as one of the best options to achieve an effective and quantitative reduction of GHG emissions from coal combustion.
