Housing of balanced channel with built-in flow conditioning Fluid medium control includes an actuator, a valve and a housing of a balanced channel, which is located inside the valve for flow conditioning in order to convert a turbulent flow inside the valve to laminar flow when fluid medium reaches a receiving section of a Pitot tube located inside the outlet valve opening. The balanced channel housing includes an opening passing through a side wall and located between the valve channel and the outlet opening. The above opening includes a partial obstacle such as partition walls or a sieve, above which fluid medium flows to convert turbulent flow to laminar flow. There are versions of a fluid medium control design. |

Method and device for adjustment of power fed to electrostatic precipitator 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. |
