摘要

A compact coiled denuder has been designed and its performance evaluated both theoretically and experimentally. The design is based on special features of laminar flow in a curved tube, which significantly enhance the mass-transfer Sherwood number governing gas collection at the wall. At 10 standard L/min (slpm) the gas collection efficiency for SO2, using a sodium carbonate/glycerine wall coating, was measured to be 99.3 ± 0.5%, while losses for particles in the range of 0.02–2.5-μm diameter averaged well under 5%.
