preheater of cement plant

Cement Preheater is also namedprecalciner. Vertical preheater is one of the main equipments of active limestone. The main function is to sendlimestone materialssent by the upper part to the preheater body, while using the emitted high temperature gas after calcination, preheat the materials to about 900 evenly.

Preheatertower maintenance practices favor gunned installation for improved logistics and speed of application except where build-ups form. Cast linings with smooth surfaces help manage build-up formation and removal. 60% alumina low-cementcastables and gunning mixes have a great deal of versatility and strong alkali resistance for use in ...

Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner. With the additional heat, about 85%-95% of the meal is decarbonated before it enters the kiln Basic principle of a precalciner cement kiln.

S. Laroche, in Steam Generators for Nuclear PowerPlants, 2017. 4.2.2.3Preheaterthermal plate leakage. The integralpreheaterwith crossflow usually includes a thermal plate that separates the feedwater from the recirculating flow from the downcomer flow entering the tube bundle. There is a small clearance gap between the tubes and the thermal plate and leakage is possible through this gap.
