Abstract |
The report gives results of an assessment of the potential use of high-gradient magnetic separation (HGMS) as a means of collecting gas stream particulates. The assessment included both experiments and analyses of theoretical models. Phase I included evaluations of theoretical explanations of HGMS and published reports of liquid system applications. A bench-scale apparatus was constructed, and HGMS experiments were conducted using redispersed dust from a basic oxygen furnace. High efficiency collection of fine particulates was achieved with both high throughput and reasonable projected energy requirements relative to conventional devices. In Phase II, experiments were scaled up to 0.8 cu m/s (1700 CFM). Dusts from basic oxygen and electric arc furnaces were redispersed and collected. Results show that submicron particles can be collected with 90-plus % efficiency using applied magnetic flux densities of 0.2-0.4 T. With superficial gas velocities up to 11 m/s, the pressure drop across the HGMS device was typically less than 1.5 kPa (6 in. H20). Even lower fields can be used successfully at the expense of higher pressure drop or reduced throughput. |
