Abstract |
The report gives results of efforts to provide a generated output with an appropriate mass and concentration of fresh, dry, fine metal oxide particles for bench or pilot scale fine particulate collection research and development work. The work involved two electric arc aerosol generators: one using a single consumable electrode of welding wire; the other, two comsumable wire electrodes of a commercially available electric arc metallizer. The generated aerosols were exhausted into a duct system and sampled using membrane filters. The single electrode generator produced 0.67 g/cu m of 0.1 micrometer diameter iron oxide particles as sampled by an Andersen Stack Sampler. The mass emission rate with an average of 1.95 g/min varied within a + or - 12% range. The double electrode generator produced submicron particles (measure by scanning electron microscopy). Mass volumetric concentrations ranged from 0.7 to 2.0 g/cu m for zinc oxide aerosols. The mass emission rate averaged 8.6 g/min for the zinc oxide aerosols and 7.7 g/min for the iron oxide aerosols. (The zinc oxide was ZnO and the iron oxide, Fe3O4.) The double electrode generator was further tested and validated for reproducibilities of total mass volumetric concentration and basic particle diameter distributions. Variables of operation were investigated to determine their effect on the mass volumetric concentration of the aerosol. |
