Boiler Operation, Maintenance & Water Treatment Technology (ISBI License)
Boiler Operation, Maintenance & Water Treatment Technology (ISBI License)
OBJECTIVES
To understand the history of combustion and the theory of boiler control and operational safety. Boiler and Steam Generation theory will be covered as an underpinning knowledge and this will be built upon with a more detailed insight into the technologies used
WHO SHOULD ATTEND?
The course is for operators, from junior level to supervisors who require an understanding of combustion and control systems as part of their duties in a large petroleum plant such as a refinery. It would also be of use to those concerned with boiler maintenance such as mechanical and instrument technicians.
