How much temperature is maintained during quicklime manufacture in the calcination zone of the vertical shaft kiln ?
Correct answer: C. 1000°C
- A. 500°C
- B. 750°C
- C. 1000°C
- D. 1500°C
Explanation
Limestone calcination requires roughly 900 to 1100°C, with about 1000°C being the standard value used for the calcination zone. At this temperature, calcium carbonate decomposes into quicklime and carbon dioxide.
