There are many problems affecting the performance of boiler dust collectors, which need to be analyzed according to actual conditions. Can be roughly divided into 4 situations:
(1) Smoke Humidity
Flue gas humidity can change the specific resistance of the dust. Under the same temperature conditions, the greater the moisture content in the flue gas, the smaller the specific resistance. Dust particle adsorbs water molecules, and the conductivity of dust increases. As the humidity increases, the breakdown voltage increases, allowing the work under a higher electric field voltage, so that the dust removal effect is significantly improved.
(2) Flue gas temperature
The gas temperature can also change the specific resistance of the dust. In addition, the viscosity of the gas increases with increasing temperature, and the viscous assembly reduces the drive-in speed. The effect of high temperature gas on the boiler dust collector is mainly negative, so try to keep the boiler dust collector running at low temperature.
(3) Smoke composition
Different other components have great influence on the volt-ampere characteristics and sparkover voltage of the boiler dust collector.
(4) Smoke pressure
Under the same conditions, when purifying high-pressure gas, the pressure of the electrostatic precipitator is higher than that of purifying atmospheric gas, and the voltage is also increased. The dust collection efficiency is also high.
