Outside thermal Russia - Tari - kiln

摘要

[Summary] In the external heating rotary kiln with Disclosed is a small ceramic materials and refractory layer having a thermal conductivity, and provides an externally heated rotary kiln which can reduce the start-up losses to be able to significantly reduce the heating time at startup. A hot air that has been generated in a hot air generator 23 by opening the valve 26 at the time of startup, is introduced from the outlet 6 into the heating chamber 3c at the same time, the carrier gas inlet 15a By allowing to flow into the kiln main body 1 together with the carrier gas from simultaneously heated from inside and outside of the kiln body 1.
