Abstract
Zinc coated tubes are cleaned by means of steam, and the zinc residue -- steam mixture is blown into a nozzle which is heated, and discharged into a noise attenuation chamber; the latter discharges into an expansion chamber, which in turn discharges into a filter. The mixture is diluted in the attenuation chamber by air sucked in from the outside along a tortuous path.
