In this work we consider the electron kinetic equation and obtain electron velocity distributions and corresponding moments. This model represents a generalization of Chodura's [1] by inclusion of electron‐electron and electron inelastic collisions. We find out that ee collisions in the edge plasma reduce the heat flux significantly and cannot be neglected. Contrary to this relatively weak inelastic collisions do not affect the electron heat flux. (© 2014 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
