Evaporation of free moisture and bound moisture in the 
form of droplets lying on a rough surface, and also moisture bound 
with forest combustibles (FC) of coniferous trees is studied experimentally. 
Empirical formulas are obtained for the rate of evaporation of water 
droplets under isothermal conditions as a function of the diameter 
of the droplets and the wall roughness. The laws governing evaporation 
of bound moisture of FCs and combined evaporation of free and bound 
moisture have been studied.
