An algorithm for determining kinetic characteristics of 
the process of drying of forest combustibles by the modified Hertz-Knudsen 
law in isothermal heating has been suggested and tested. It is shown 
that this algorithm allows obtaining of a stable solution of the inverse 
kinetic problem of one-dimensional determination of the heat of evaporation 
and a pre-exponential factor with an error proportional to the error 
of initial experimental data. Kinetic characteristics of the process 
of drying of certain forest combustibles are determined by the experimental 
data known from the literature.
