| Abstract |
The report describes an evaluation of an SO3 injection system for the George Neal Unit 2 boiler of the Iowa Public Service Co. in Sioux City, Iowa. Results of base line tests without conditioning indicate a dust resistivity of 6 x 10 to the 12th power ohm-cm at 118C: the precipitator's average collection efficiency was 91.3% at a specific collecting area of 42.8 sq m/(cu m/sec). Because transformer-rectifier sets tripped out, apparently due to ash buildup in the hoppers, only one precipitator efficiency test was conducted with the SO3 system operating continuously with all T-R sets operating. Results of this test were: (1) specific collecting area = 41.8 sq m/(cu m/sec); (2) collection efficiencies = 99.27% (ASME method), 98.96% (EPA method), and 98.78% (EPA method, including first impinger residue); and (3) 4 x 10 to the 10th power ohm-cm dust resistivity at 143C. An adequate accounting was made for the fate of the injected SO3. |
