| Abstract: |
| Discharge process of rotary kiln in an alumina plant was analyzed. Various technical transformations, such as transformation of kiln back ash system, structure optimization of cyclone dust collector, and optimization of high-frequency power supply for electric precipitator, were put forward and verified. After transformation, the average value of flue gas emission of rotary kiln is 28.84 mg/m3, which is far lower than the national standard of flue gas emission. |
