Tests at the Four Corners power station show that simple, economical modifications to a single-stage venturi wet scrubber for particulate removal can, by adding lime and recycled fly ash directly to the scrubber, remove 85% of the sulfur dioxide. Utility interest in the Nelms/Turton scrubber is most likely limited to existing plants and may not be applicable to new facilities. Diagrams illustrate the modest hardware involved. Advantages to the system include the fact that there is no need for a hold tank, no flue-gas reheat, no corrosive pH, and no gypsum scaling. Tests indicate that nucleation of the calcium sulfate and sulfites on fly-ash particles explains the high performance. 2 figures, (DCK)
