The electrostatic precipitator system of the lignite fired 350 MWe unit B1 of
Thermal Power Plant Kostolac B has been modernized during 2014. The results
of complex in site measurements, performed in the frame of performance
control test at the beginning of the exploitation period of the upgraded
electrostatic precipitator proved that, under normal and guarantee working
conditions of the boiler and precipitator, the emission of particulate
matter do not exceed limiting value. After the period of precipitator
further adjustments, five series of measurements in the frame of acceptance
test were performed in accordance with relevant standards. This paper
presents results of the investigation of particulate matter concentration,
laboratory analysis of the lignite, fly and bottom ash samples, working
parameters of the unit and upgraded electrostatic precipitator as well as
results of the calculations. The averaged mean particulate concentration at
the exit of upgraded electrostatic precipitator of the unit B1 during
Acceptance test was below guaranteed value. It is confirmed that adjustments
of electrostatic precipitator electrical parameters have improved
electrostatic precipitator efficiency, as well that electrostatic
precipitator could work highly efficiently in energy save mode with lower
power consumption.
