Optimization of the flue gas flow controlling devices of the electrostatic precipitator of unit 4 in TPP "Nikola Tesla"

Homogeneity of the flue gas flow through chamber an electrostatic precipitator is one basic influencing parameter on dedusting efficiency. This paper presents results a multiobjective optimization study controlling devices 324 MWe lignite fired unit A4 Thermal Power Plant "Nikola Tesla" in Serbia. The aim was to achieve better homogeneity cross-section compared original design. Additional constraints were maintain minimum as possible overall weight proposed design well pressure drop precipitator. Numerical simulations based Computational Fluid Dynamics used investigate dependence velocity distribution ducts and precipitator?s with respect geometrical parameters tested concepts turning blades. A series 22 detailed full-scale numerical models different vanes designs developed. Assessment field uniformity for each performed analysis several calculated selected vertical cross-sections After reconstruction according optimized design, measurements confirmed significant improvements precipitator, increase efficiency reduction PM emission.
