Abstract

Nonisothermal desorption and crystallization of droplets of aqueous salts solution of H2O/LiBr were studied experimentally. A droplet was placed on a horizontal heated wall. The initial concentration of salt C0 varied within 0-53 %. The wall temperature Tw varied within 80-235 °C and ambient air pressure was 1 bar. It was shown that the desorption time t1 decreases sharply with increasing Tw and at Tw < 150-160 °C. The desorption time t1 is the time until the onset of crystallization. The desorption time t1 is quasi-constant at Tw > 160 °C and increases with growth in C0.
