Pilot Scale Testing of Microwave Heating for In-Situ Decontamination of Unsaturated Zone.
Mašín, P. ; Maštalka, J. ; Sobek, Jiří ; Hájek, Milan
This artickel is focused on a microwave heating unsaturated zone performed by microwave generator (magnetron) of 6 kW and a frequency of 2 450 MHz. Application well was constructed from ceramic casing pipe, which is transparent for the penetrating microwave radiation, to inside was placed a waveguide for guiding microwave radiation. They were tested waveguides square (49 x 99 mm) and round (Ø 105 mm) consist of 4 segments with a total length of 4 m. Construction waveguides allow microwave radiation conduit and simultaneously drainage of desorbed vapors contaminants, which\nwere then drawn off conventional pump.
