A power system is provided. The power system includes a gas turbine assembly having a compressor, a combustor, and a turbine coupled in serial flow arrangement. The compressor has a compressor inlet. The power system also includes an electrostatic precipitation system coupled to the gas turbine assembly upstream from the compressor inlet. The compressor is oriented to receive working gases discharged from the electrostatic precipitation system to facilitate removing entrained matter from the working gases flowing into the compressor inlet.

A method and to a device for the electrostatic separation of fine dust particles from gases that flow through a housing (1) containing perforated plates (6) and electrodes (4, 5). An electric field is created between the electrode (4) on the inflow opening side and the electrode or electrodes (5) having positive polarity on the outflow side. The removal of negatively charged fine dust particles (9) is carried out by deposition on the inflow side of the perforated plates (6), and the removal of positively charged fine dust particles (11) is carried out on the outflow side. Fine dust particles without charge (10) are charged after the last perforated plate (6) in an ionization chamber (8) and deposit on the outflow side of the last perforated plate (6).

A maximum number of charges on aerosol particles which are measurement targets is decided as a natural number x equal to or larger than 2. First and second electrical mobility groups are derived based on x. The first group includes electrical mobility Zc(U) and electrical mobilities having voltage values equal to a voltage U multiplied by values from 2 to x respectively, and the second group includes electrical mobilities having respective voltage values equal to voltage U multiplied by irreducible fractions which are coprime to each other among values with regularity. A ratio of flow rate with which range corresponding to the electrical mobilities included in the first group do not interfere with one another and the range corresponding to the electrical mobilities included in the first group and range corresponding to the electrical mobilities included in the mobility group do not interfere with one another is calculated.
