Abstract
Major characteristics of two alumosilicate filters based on fly ash microspheres and porous chamotte were studied for high-temperature trapping of Cs-137 vapours.
To determine aerodynamic resistance of the filters, a test facility was designed and built to determine the aerodynamic resistance of the filters. It was shown that porous chamotte had significantly lower resistance than that of the filter based on fly ash microspheres at linear airflows up to
15 cm/sec.
Thermal treatment at 1400-15000С made it possible to increase mechanical strength of the filter based on porous chamotte factors of 1,5- 3,4, without any significant changes of other characteristics that exceeded similar parameters for the filter based on fly ash microspheres.
