ABSTRACT:
For the reliable condensation of steam on condensation nuclei in an aerosol flow and therefore for enlarging the particles in the aerosol, the invention provides a method which is characterized in that condensation nuclei are passed through an inner area of an evaporating zone forming a flow area, the liquid to be evaporated is contacted with the flow area and evaporated therein and the thus produced steam is condensed on the condensation nuclei. the invention also provides an apparatus for condensing steam on condensation nuclei with an inlet for condensation nuclei and an evaporating zone constructed in such a way that a flow area for the condensation nuclei has a heated liquid duct open thereto and that a condensation flue is connected to the flow area. The invention also provides methods and apparatuses for counting particles, for producing monodisperse aerosols using the aforementioned method or the aforementioned apparatus.
