The solution of the conjugate problem of convective-conductive 
heat transfer in the channels of power plants is presented. The problem 
of convective heat transfer in the gas phase is solved by the integral 
theory of heat transfer. A one-dimensional problem of conductive heat 
transfer in the material of the wall is solved by the finite-difference 
method. Relative laws of heat and mass transfer and friction are obtained 
by numerical integration with respect to the boundary-layer thickness. 
The effect of the material and geometry of the wall on the level of 
problem "conjugation" is studied.
