| Abstract |
The report gives highlights of an EPA research program aimed at developing and verifying an accurate theory of particle charging for conditions that are typically found in industrial electrostatic precipitators. A new theory was developed, in which the thermal motion of ions is assumed to dominate the charging process. The theory was shown to agree to within 15 percent of published experimental data. To further verify the new theory, experimental determinations of particle charging were made, using a mobility analyzer to find the end points of particle trajectories in an electric field. For particles of 0.32 to 7 micrometers diameter, the agreement between theory and experiment was within 20 percent. |
