Description:
The report gives results of using a 5100 cu m/hr mobile pilot plant to evaluate the effectiveness and economics of applying high-gradient magnetic filtration (HGMF) to particulate emission control. A 4-1/2 month test program was conducted at a Pennsylvania sintering plant to characterize the performance of the pilot plant and to demonstrate its practicality under long-term operation. Analysis of the results indicates that high-efficiency collection can be achieved economically if HGMF is applied to steel industry dusts that are more homogeneous and more strongly magnetic than the tested sinter dust. The report describes laboratory pilot-plant work that demonstrated collection efficiencies greater than 99% with basic oxygen furnace and electric arc furnace dusts. The development of a filter cleaning system and the design and construction of the pilot plant are discussed. Experimental data are reported.
