Clinkerization Cement Plant Optimization

Clinkerization Cement Plant Optimization

Lower Cyclone Temperature is considered most important and stable temperature in preheater to control pre-calciner fuel rate. It is generally maintained manually or by PID loop in the range of 10 0 C, in the range 850-900 0C to ensure calcination between 90% to 95 %.

The cement kiln

The cement kiln

In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker minerals form.

In the cement mill ESP, inlet dust load can exceed 700 g/Nm 3. Our ESP includes a pre-separator hopper to separate coarser dust and maximise overall efficiency. FLSmidth’s coal mill ESP can be designed with a N 2 or CO 2 purging system. Explosion flaps can be added to the roof to meet ATEX/NFPA standards requirement for vent pressure clearance.

Fire and Explosion Hazards in Cement Manufacturing

Fire and Explosion Hazards in Cement Manufacturing

Cement plants are energy intensive industries and have a large number of heavy duty electrical equipment used for distribution, control, and electric power utilization. Large quantities of insulation oil used in equipment like switchgears, transformers, and capacitors are combustible in nature and pose a major fire hazard.
