Abstract
Amager unit 1 is a 350 MW multifuel suspension-fired plant commissioned in 2009 to fire biomass (straw and wood pellets). Increasing corrosion problems in the flue gas cleaning system were observed in the gas-gas preheater (GAFO), the booster fan and flue gas ducts. Chlorine containing corrosion products/deposits were detected. An on-line corrosion measurement system was established to determine corrosion mechanisms. It was revealed that many shutdowns/start-ups of the plant influence corrosion and result in decreased lifetime of components and increased maintenance. The change of fuel from woodchip + straw pellets to only woodchip pellets reduced corrosion significantly.
