Title: Boiler Operations Maintenance & Steam Management 5
Start Date: 03 – January -2021, End Date: 07- January- 2021
Venue: Dubai, UAE
In any of the 5 star hotels. The exact venue will be informed once finalized.
Boiler operations are important unit operation in all oil and gas facilities, refinery operation and gas processing. This course is designed to enhance the knowledge of boiler operation and practical aspects of operational and control system in boiler operation.
The course is designed to give a detailed understanding of boilerconstruction, operation with design considerations as well as more detailed operations, control and safe guard system.
Combustion process described in detail is part of this course. Understanding air – fuel ratio. Safe operation practices.
Course sessions will emphasis on implementing the procedures/documentations & control measures required for ensuring safe operation, integrity and best operational practices.
Design constrains, operational issues, troubleshooting etc will be included with case studies and experience transfer from similar examples from other countries.
The program is ideal for junior, supervisory and middle management level personnel who operating and /or supervising oil, gas, and refinery operation.

Pre & Post Tests will be conducted
Case Studies, Group Exercises, Group Discussions, Last Day Review & Assessments will be carried out.
A highly interactive combination of lectures and discussion sessions will be managed to maximize the amount and quality of information and knowledge transfer. The sessions will start by raising the most relevant questions, and motivate everybody find the right answers. You will also be encouraged to raise your own questions and to share in the development of the right answers using your own analysis and experiences. Tests of multiple-choice type will be made available on daily basis to examine the effectiveness of delivering the course. Very useful Course Materials will be given.
