  2. 1. High temperature corrosion in biomass-fired energy applications : Alloying effects and test environment comparisons

    Author : Ragna Elger; Rachel Pettersson; Inger Odnevall Wallinder; Rikard Norling; Gordon Tatlock; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; High temperature corrosion; biomass; waste; superheater corrosion; austenitic steel; biomass gasification; alumina-forming austenitic stainless steel; thermodynamic modelling; kinetic modelling; Kemi; Chemistry;

    Abstract : To reduce the greenhouse effect, the use of renewable fuel has to be increased. As renewable fuel has different characteristics compared to fossil fuel regarding content of trace metals, alkali, chlorine and sulphur, the corrosion characteristics in high temperature energy processes have to be evaluated.

  4. 2. Biomass gasification in fluidized bed gasifiers : Modeling and simulation

    Author : Guilnaz Mirmoshtaghi; Erik Dahlquist; Jan Brandin; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Using woody biomass as a resource for production of biofuel, heat and power through gasification has been studied for years. In order to reduce the cost of operating and to design the full-scale gasification plant developing a general model to be applicable for different ranges of input data with acceptable level of accuracy, is needed.

  5. 3. Characterization of particulate matter from atmospheric fluidized bed biomass gasifiers

    Author : Eva Gustafsson; Michael Strand; Marcus Öhman; Linnéuniversitetet; []
    Keywords : biomass gasification; fluidized bed; particulate matter; particle morphology; particle elementary composition; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Abstract : Through biomass gasification, biomass can be converted at high temperature to a product gas rich in carbon monoxide, hydrogen, and methane. After cleaning and upgrading, the product gas can be converted to biofuels such as hydrogen; methanol; dimethyl ether; and synthetic diesel, gasoline, and natural gas. READ MORE

  6. 4. Conversion of biomass and waste using highly preheated agents for materials and energy recovery
