Abstract:
In Austria the utilization of biomass and biomass waste has a long history. At the moment eleven fluidized bed combustors and three fluidized bed gasifiers utilizing biomass or biomass waste operate with a thermal capacity of around 640 megawatts (MW) and 33 MW, respectively. Around two third of the installed capacity, coming from eight fluidized bed combustors (FBC), use the circulating fluidized bed technology. In general, the FBC plants can be assigned to two industries: the electricity and heat producing industry and the pulp and paper industry. Here, biomass is utilized by the electricity and heat producing industry, whilst the pulp and paper industry utilizes biomass waste in form of bark, waste wood and rejects. The three biomass gasifiers utilize biomass and can be related to the electricity and heat producing industry. This work aims to give an overview of the existing FBC plants and the employed technology in Austria with a special focus on the fuel processing and flue gas treatment. In addition, differences in the fuel processing as well as in the flue gas cleaning process of biomass and biomass waste plants are analyzed. This also addresses the specific needs of the different fuels on the basis of fuel properties. For this purpose, the existing FBC plants are categorized according to their related industry, bed type, fuel processing and flue gas cleaning. The insights gained are used to deduce the differences in fuel processing and flue gas treatment systems of the two different types of fuel. Moreover, selected systems are examined in more detail in order to obtain the state-of-the-art fuel processing and flue gas treatment systems of FBCs utilizing biomass and biomass waste in Austria.
