Conclusions

Distribution of flue-gas temperatures in the cross section of the preheat zone of a tunnel kiln depends in particular on the reliability of sealing the roof and the hearth system.

Variations in the temperatures of the flue gases in the firing zone depend mainly on the distribution of fuel and air in the cross section of the working region of the kiln, which is associated with the design of the burners, their arrangement, and their working conditions.

The nature of the changes in the temperature of the surface at the settings is mainly the same as for the flue gases.

A serious variation in temperature develops over the cross section of the setting column during heating, which reaches 100–150°C when no soak is provided.

To level out the variations in temperature over the thickness of the column it is necessary to arrange a soaking at constant surface temperature at the end of the firing zone. Its duration depends on the material being fired, the thickness of the column, the heating rate, and the value of the stated final variation in the temperature.

It is necessary to carry out an investigation to select the optimum burner design and arrangement.
