Electrostatic precipitators (ESPs) are the most widely applied at TPPs as ash collectors, since they allow to clean gases from ash with an efficiency of 0,990 ... 0,998 at the hydraulic resistance of less than 200 Pa. Capital expenditures for construction of ESPs are high, as these devices are metal-intensive, require large space, are equipped with special stepping up-rectifier units of power supply.
