Studies on the reduction of dispersed emissions from a low-power household boiler in a plasma ionic wind zone

Abstract

Gas ionizator is a device for electrostatic precipitation and is widely used to separate fine particulate matter (FPM) from small- and large-scale industrial exhaust gases. Two variations of electrodes design, rod and rectangle-toothed saw were used. The mass and number concentrations of six FPM fractions were detected. Stronger vortices occur at higher EAD/Re² ratios compared to the secondary electroaerodynamic (EAD) gas velocities. A deposition efficiency higher than 94.9 % was achieved at a gas velocity of 0.2 m/s. The FPM capture efficiency at voltage up to 20 kV is higher more than 7 % than at a voltage of 15 kV.
