Conclusions
A Fortran program has been developed for calculation of the thermal conditions of the walls of tunnel and batch kilns taking into consideration the two-dimensional configuration of the walls, the relationship of the thermophysical properties of the materials to temperature, and the nonlinear character of the boundary conditions.
It was shown that in the walls of tunnel and batch kilns the vertical heat transfer has a significant influence both on the temperature field of the walls and on the structure of the thermal losses.
Variations of walls with thermal insulation properties have been developed. In comparison with the walls of existing high-temperature kilns, the introduction of them makes it possible to reduce thermal losses by 25–35%.
