The electrostatic precipitator in a power plant offers several practical benefits for potential customers. First of all, it ensures that environmental regulations are not broken by drastically reducing particulate emissions; this helps to avoid penalties and promotes a positive public image. Second, it also results in savings on the power plant's operation costs and increases efficiency. This is because it raises better air quality within the power plant as well as reducing maintenance overheads associated with ash removal and machinery wear and tear. Moreover, it is a low energy consumer operating at high collection efficiency rates: well over 99%. Finally, the electrostatic precipitator has a long service life and can run practically trouble-free for a long time. All this means its continuous operation well rewards any initial small investment in terms of maintenance costs--few plants would not appreciate these advantages. It will be seen as a first-cost effective solution by power plants which want to shrink their carbon footprints and minimize operations outgo.
