Specific heat consumption of clinker

WebJul 16, 2024 · CaF2, as mineralizer improves the rate of clinker formation by another reaction pathway involving the formation of new, intermediate minerals (e.g. 3C3S.CaF2) at temperatures in the range 1000 °C... WebThe current state of the preheater limits heat transfer resulting in high gases temperatures exiting the preheater usually above (350–400)°C. This results to high specific heat consumption within the pyro processing line ranging from 900 to 950 kcal/kg clinker.
