Quick Answer: Why Clinker Is Used In Cement

Independent of the raw meal used, the different clinker phases were formed in three stages: 1. C2S, C3A and C4AF formation at ~900-1350 °C; 2. Clinker melt formation at ~1350-1400 °C; and 3. C3S formation at >1350 °C. What is the difference between cement and clinker? Clinker is a nodular material which is used as the binder in cement products.

Avoiding Clinker Formation in Thermal Power Plant Boilers

Aug 17, 2010· Aug 17, 2010· Clinker formation is a serious problem in boilers of thermal power plants which results in forced outage and generation loss. Removal of clinkers from the water wall is difficult thus requires pneumatic hammering. Low quality coal having less gross calorific value, high mineral content, high ash content, and the over-firing of molten slag are causes of clinker formation.
