ABSTRACT:
A process for producing an aerosol stream, which is conducted through an essentially aerosol-free vapor and/or gas stream to prevent undesirable precipitation of particles contained in the aerosol stream, is augmented by additionally employing thermophoresis. For this purpose, the vapor and/or gas stream is heated to a temperature which is higher than the temperature of the aerosol stream. Thermophoresis then causes the particles to be held within the aerosol stream.
