This paper discusses results of tests conducted by EPA on the efficiency of hot-side electrostatic precipitators in controlling SOx and fly ash emissions from industrial boilers. In this case, Unit 3 of Duke Power Company's Allen Steam Station was used for the tests. Test methods used on the hot-side ESPs were EPA sanctioned. Replicated tests were made over a 8 day period. Efficiency of the hot-side ESPs depended on the size of the particle to be collected. Efficiency was 99.8% at 4 micrometers; 99.5% at 8 micrometers; and 98% at 0.6 micrometers. The average efficiency percentage was 99.69%. Results of the tests also indicated that the location of the ESP on the hot side of the air preheater greatly increased the efficiency of particulate collection.
