Training methodology

The instructor relies on a highly interactive training method to enhance the learning process. This method ensures that all the delegates gain a complete understanding of all the topics covered. The training environment is highly stimulating, challenging, and effective because the participants will learn by case studies which will allow them to apply the material taught to their own organization.

Special feature

Each participant will receive a copy of the following materials written by the instructor:

  • Excerpt of the relevant chapters from the Power Plant Equipment Operation and Maintenance Guide published by McGraw-Hill in 2012 (800 pages)
  • Heat Rate Optimation Manual (includes practical information about all the methods used to optimize the heat rate in coal power plants - 300 pages)
