Course Description
The pyroprocess system is considered the heart of the cement manufacturing process. It is also where most of the thermal energy is used.
The pyroprocess operations and simulation seminar offers a thorough study of the design and function of the kiln systems, including but not limited to the latest methods for optimisation and proposals for upgrades and modernisation of the current system.
The seminar will focus on the understanding of how the pyro system works, the influence between the burnability of the raw materials and the operating strategies. The relationship between the chemistry of the raw materials, fuels, burner settings and operation of the preheater/calciner/kiln/cooler systems.
What Do Participants Learn?
- Understanding of how the system is designed to operate.
- The relationship between the raw feed chemistry, fineness, fuel characteristics, burners and flames, kiln operation efficiency and clinker quality.
- The effect of operating techniques and manufacturing costs.
- How to analyse and troubleshoot kiln systems and identify areas for improvement with system upgrades and modernization options to improve operations and productivity.
- Improved synergy in between the production, quality and maintenance departments for better communications and cooperation.
Who Should Attend?
- CCR Operators and site operators
- Production Engineers and Mechanical Engineers
