| Zusammenfassung |
| The efficiency of an electrostatic precipitator (ESP) for reducing wood
combustion emissions was investigated. Real-time measurements were conducted
by directly reading the change in frequency of the tapered element in a
Thermo Scientific 1400a TEOM. These measurements have been shown to be
influenced by the charge on the aerosols reaching the tapered element such
that the TEOM overestimates mass concentration. This electrostatic effect
was crosschecked with particle mass concentration and particle number
concentration measurements where no influence was observed. Placing a
radioactive neutraliser prior to the TEOM leads to agreement between
observed ESP efficiencies as measured by both the TEOM, mass filters and a
CPC. |
