AB - Experimental data on desorption and nucleate boiling in a droplet of LiBr  water solution were obtained. An increase in salt concentration in a liquid  layer leads to a considerable decrease in the rate of desorption. The  significant decrease in desorption intensity with a rise of initial mass  concentration of salt has been observed. Evaporation rate of distillate  droplet is constant for a long time period. At nucleate boiling of a  water-salt solution of droplet several characteristic regimes occur: heating;  nucleate boiling; desorption without bubble formation; formation of the  solid, thin crystalline-hydrate film on the upper droplet surface, and  formation of the ordered crystalline-hydrate structures during the longer  time periods. For the final stage of desorption there is a big difference in  desorption rate for initial salt concentration (C0) 11 % and 51 %. This great  difference in the rate of desorption is associated with significantly more  thin solution film for C0 = 11 % and higher heat flux.
