  1. 11. Propensity of bed materials used in dual fluidized beds to retain ash-forming elements from biomass fuels

    University essay from

    Author : Björn Folkeson; [2014]
    Keywords : Fluidized bed; ash retention; gasification; combustion; bed material; Fluidiserad bädd; askämnen; förgasning; förbränning; bäddmaterial;

    Abstract : 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.

  3. 12. Experimental investigation of thermal conversion of solid waste under high temperature agent (steam/air)

    University essay from KTH/Samhällsplanering och miljö

    Author : Roger Gołombek; [2013]
    Keywords : thermal conversion solid waste steam;

    Abstract : Most of the problems with providing a continuous and sustainable energy supply for the worldwide society are negative consequences to the environment and its living habitants steaming from uses of conventional technologies. Those consequences should be minimized by developing and improving new technologies as well as by utilization of other type of feedstock than fossil fuels, such as biomass, industrial or municipal solid waste.

  4. 13. Optical study of fuel particle properties in an entrained flow reactor

    University essay from Institutionen för tillämpad fysik och elektronik

    Author : Per Holmgren; [2013]
    Keywords : ;

    Abstract : Biofuels provide a renewable option with large global potential for replacement of non-renewable fossil fuels. Some of the developing systems for thermal conversion of solid biomass depend on small particles or powders for feeding and dispersion in the reactors. READ MORE
