The course ”Maintenance of boiler systems” is an application-specific course within maintenance, extensive materials, inspection techniques, water treatment, corrosion, cracks and damage prevention.

Boiler system maintenance and inspection  Print page  Send to colleague

Participants
Mechanical engineers and operation managers and technicians with responsibility for operation and maintenance of boiler- and related types of energy and processing plants.
Design, service- and repair-technicians of boilers, exhaust valves and related pressure systems
Inspectors of boilers and pressure vessels as well as equipment exposed to corrosion and creep at high temperatures.

Target
The participants will acquire:

Application oriented knowledge on materials, corrosion and corrosions prevention and condition assessments and water treatment in connection with steam as well as hot water boilers. The area will cover small boiler plants in industry as well as the somewhat larger power plants.
Biomass and waste incineration corrosion problems are also dealt with.
Knowledge on NDE-inspection techniques for condition assessments and on damages and damage prevention.
