Coal in the cement industry

For production of cement the temperature of clinker should be around 1500oC, which can be achieved when flame temperature is maintained at 1700oC. This is achieved by providing preheat to the secondary air. If high moisture coal is used in direct firing system, there may be an excess of moist primary air and required temperature may not be obtained. However, in indirect firing system using dry primary air a …
