Domestic Lignite Quality and Combustion Technology Enhancement for Energy Efficiency Increase and Reduction of Harmful Gases and Particulate Matter Emissions from Thermal Power Plants of Public Enterprise ”Electric Power Industry of Serbia”

Project subject is an implementation of the coal pre-drying technology to the thermal power plants of PE “Electric Power Industry of Serbia” with following positive effects: a) energy efficiency increasing, followed by sufficient reduction of the pollutants (SOx, NOx and particles) and GHG emissions and reduction of deposited ash quantities; b) extended boundaries for lower fuel quality usage at the thermal power plants and spreading range of existing lignite reserves that can be used in the future; c) specially designed low-NOx swirl burners for dry pulverized coal combustion can completely replace existing system for liquid oil start-up and fire support; d) specially designed low-NOx swirl burners dry pulverized coal combustion can enable full capacity of thermal power plants of PE EPS during the winter when energy consumption is the highest in Serbia. Main expected results of the project are: data base of relevant characteristics of domestic low-rank lignite available for exploitation in PE EPS thermal power plants together with the set of implemented laboratory equipments and accredited methods for physical-chemical and explosiveness fuel characterization, optimized design of swirl burner with the defined geometry-thermal operating conditions, concentration and flow conditions for the combustion of pulverized dried domestic lignite and finally, preliminary technical design for the implementation of the chosen pre-drying technology for one unit of the existing power plants
