The shell internal wall is lined with firebricks for the shell protection subject to respective conditions. Furthermore, heat-resisting bricks are used for the lining as needed. The flow directions of the material and hot air (high temperature gas) are countercurrent, in general. According to the applications, however, concurrent flow may be introduced or a hot air generation unit may be provided in addition. It is also possible to mix solid fuel in the material or to provide a self-combustion process in the kiln.
