Separation Efficiency of the APFenergyFilter™
The removal efficiency of an electrostatic precipitator describes its ability to remove particles from a gas stream and is often expressed as a percentage of the effective removal of particles from the gas stream. While electrostatic precipitators are very effective at removing a wide range of particle sizes, using the right type of electrostatic precipitator can have a positive impact on certain factors.
Separation Efficiency
Investigations have shown that the overall separation performance of electrostatic precipitators essentially depends on the following influencing factors:
-
particle size
-
Distribution of the exhaust gas volume flow to all electrodes
-
Specific electrical resistance of the dust layer on the collecting electrodes, depending on temperature, proportion of unburned particles from the boiler, humidity and gas composition
Example biomass:
For biomass firing, the main proportion of particle sizes is in the range of < 1 μm, ie electrostatic precipitators must have a high separation efficiency, especially in this particle size range. The APFenergyFilter™ is characterized by the fact that it achieves a high degree of separation in the range of < 1 μm and is insensitive to sticking due to soot particles and flying sparks from the boiler.
The determined data show dust concentrations at the filter outlet of
10 mg/Nm³. The degrees of separation range from 97.8 to 99.2%.
