FIELD: process engineering.SUBSTANCE: invention relates to control over electrostatic filter. Proposed method comprises the steps whereat: algorithm of control over power applied between at least one precipitation electrode 28 and one discharge electrode 26. Note here that said control algorithm includes direct or indirect adjustment of at least one power range VR1, VR2 and that of power linear variation rate RR1, RR2. Process gas temperature T1, T2 is measured to select, when said algorithm includes power range adjustment, the power range VR1, VR2 proceeding from measured temperature T1, T2 while magnitudes VT1, VT2 to upper limit of power ranges VR1, VR2 at high process gas temperature T2 is lower than that at low process gas temperature T1. Power adjustment rate RR1, RR2 is selected proceeding from measured temperatures T1, T2 when said algorithm includes power linear variation adjustment rate. Note here that power adjustment rate RR1, RR2 at high temperature T1 is lower than that at low temperature T2. Algorithm of control over power applied between at least one precipitation electrode 28 and one discharge electrode 26 is used to adjust said power.EFFECT: longer life.12 cl, 10 dwg |
