18. Propensity of bed materials used in dual fluidized beds to retain ash-forming elements from biomass fuels
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and TechnologySammanfattning : The main aim of this work was to investigate the propensity of bed materials to retain ash-forming elements from biomass under conditions relevant to dual fluidized bed gasification (DFBG). The investigation was carried out in a laboratory-scale bubbling fluidized bed reactor in which biomass was gasified with steam and the unconverted char was combusted in the temperature range 800–900 ° C.
