Abstract
The report gives results of a performance test and engineering analysis of a mobile-bed scrubber on a full-scale coal-fired utility boiler. The scrubber nominally operated at the design particulate removal efficiency of 95%, but the concentration of submicron particles was greatly influenced by mist entrainment. The entrainment resulted in a difference of aerosol penetration through the scrubber as a function of elemental composition and outlet submicron particle concentration independent of pressure drop through the scrubber. The variable concentration of submicron entrained particles made the application of the penetration data as a function of particle size to development of performance models unfeasible. The engineering analysis showed that the 1972-installed cost was $29/kw and the annual operating cost is 0.5 mills/kwh (75% availability). An initial decline in scrubber availability after startup resulted from now-corrected minor design problems. Steadily improving reliability is attributed to the utility's providing maintenance and solving operating problems.
