Experimental and theoretical investigate the process of non-isothermal desorption of water solutions of lithium bromide in the spheroidal state on the horizontal heating surface. It was established experimentally that on reaching average weight of the salt concentration of 15 ÷ 23% and 32 ÷ 34%, respectively, at a temperature of the heating surface 400 and 600° C, the solution direct contact with the heating surface and the boiling crisis is replaced by a crisis mode of “explosive” boiling up. Some possible causes of the phenomenon were investigated: decrease in the thickness of the vapor layer with increasing concentration, the effect of temperature of the heating surface, radiation heating and capillary instability of interphase.
