| Abstract: |
| Rotary kilns, as combustion equipments, which supply necessary heat for material calcination, are widely applied to metallurgy, refractories, cement industry, chemical industry and paper making industry. Because of the lower heat exchange efficiency between fiery gas and materials, there is lots of waste heat resources which is produced during the process of production, and how to utilize these waste heat resources has become very important. Domestic and foreign research status and analysis of waste heat resources utilization of rotary kilns is totally and systemically discussed in this paper based on preheating technology and cooling technology, and the trend of the research on preheating technology and cooling technology is put forword. |
