The report gives results of fine particle collection efficiency measurements of a gas-atomized spray scrubber, cleaning effluent gas from a No. 7 gray iron cupola. Tests were made at several levels of pressure drop and liquid/gas ratio. Particle size measurements on inlet and outlet gas streams were made with cascade impactors and an A.P.T. screen-type diffusion battery. The particle mass collection efficiency at a pressure drop of aout 100 cm W.C. was 91% for particles with a mass median diameter of about 0.4 micrometers A. Scrubber inlet gas flow rate varied, because the cupola was operated with an open top, from 4.0 to 12.6 A cu m/s (8,500 to 27,000 acfm). Air leakage into the scrubber system caused serious operating problems until most of the leaks were sealed. The penetrations for 1 micrometer A diameter particles were about as predicted by the mathematical model; however, smaller particle penetrations were lower, and larger particle penetrations were higher, than predicted. The latter two effects are believed due to water condensation effects and entrainment, respectively.
