The problem of low efficiency of collecting ash from low-sulphur coals in electrostatic precipitators (ESPs) is well-known. It is stipulated by high specific electrical resistance of ash and presence of backward corona in layers of deposits at ESP electrodes, sharply worsening the ash collecting efficiency.
