  Thermal energy analysis of a lime production process: Rotary kiln ...

  2016415 · A gas burner resides at the end of the rotary kiln. Limestone absorbs heat by convective and radiative modes, and after reaching calcination temperature, it will be decomposed to lime (CaO) and carbon di-oxide (CO 2 ). The thermal energy produced by a natural gas burner is mainly consumed in the calcination reaction.
