Abstract

Alkali chloride deposition can lead to superheater corrosion in power plants with high steam values. Biomass often containes alkalies and chlorides in such a form which enable alkali chloride vaporisation from fuel and condensation to superheaters. Hence, such biomass cannot be combusted alone in effective power plants. This work optimises protective reactions in co-combustion leading to destruction of biomass originated alkali chlorides before their condensation. Impactors (ELPI and BLPI) and FTIR have been used to follow the key reactions and deposit probes were used to find the strongth of Cl-deposition.
