Aerosol in the steam turbine?
Kolovratník, Michal ; Hrubý, Jan ; Ždímal, Vladimír
The small amount of admixtures in steam circuits of power stations influences their life-expectancy and energetic efficiency. It is likely that non-volatile admixtures are in the environment of the dry (superheated) steam transported in the form lf dry particles or concentrated nanometric droplets, aerosols. For the detection of these particles a new sampling line is proposed, using the aerosol technology. It will be possible to connect the sampling line to sampling ports of a steam turbine.

Model růstu kapky ve směsi metanu, nonanu a přesyceného oxidu uhličitého
Krejčí, A. Petr
In order to use existing setup, based on shock tube, for nucleation rate measurement in mixture of methane, nonane and supersaturated carbon dioxide, the problem of fast growing droplets has been solved. Series of experiments with parameters suggested on the basis of developed model has been performed recently. The experiments were successful. Scattering and transmitted intensity signals allow extracting information about CO2 droplet growth and droplet number density.
