Coal with low volatile content is not easy to catch fire. Long black flames will appear in the kiln, and the high-temperature zone is more concentrated. In order to make the flame of the coal-fired rotary kiln longer and the calcination more uniform, the volatile content of coal is generally required to be between 22% and 32%. Ash. The ash ...
