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


Mechanical engineers and operation managers and technicians with responsibility for operation and maintenance of biomass-fired boilers - and related types of energy and processing plants.
Service and repair technicians of biomass-fired 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, fired with biomass.


Incineration processes:

Cracks and fractures in biomass-fired boiler systems:
   • Creep, fatigue and stress corrosion cracking

Corrosion in boilers and water chemistry:
   • Deposits and corrosion forms
   • Treatment of boiler water and boiler feed water
   • Off-load corrosion and corrosion prevention

Corrosion in flue gas cleaning systems of biomass-fired boilers:
   • High temperature materials and corrosion
   • Acid dewpoint corrosion
   • Biofuels and waste incineration

Information and demonstration of NDE techniques:
