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

   Författare :Ragna Elger; Rachel Pettersson; Inger Odnevall Wallinder; Rikard Norling; Gordon Tatlock; KTH; []
   Nyckelord :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;

   Sammanfattning : 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.

3. 17. Integrating Biomass in Existing Natural Gas-Fired Power Plants

   Författare :Erik Pihl; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forest Residue; Modeling; Hybrid Combined Cycles; Biomass; Gasification; Efficiency;

   Sammanfattning : Using biomass for utility heat and electricity generation can supplement use of fossil fuels, whose emissions of carbon dioxide likely risk causing serious climate change and ocean acidification. Biomass as energy source is a limited resource and when used as fuel in thermal power plants this currently results in higher production costs than using fossil fuels such as natural gas and coal.

4. 18. Numerical modelling of biomass thermochemical conversion and potassium release

   Författare :Seyed Morteza Mousavi; Strömningsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical modelling; particle model; bed model; CFD simulation; biomass; pyrolysis; ; combustion; gasification; potassium release; alkali;

   Sammanfattning : The use of biomass as a renewable source of energy has been increasing over the past few decades, and biomass is regarded as a promising replacement for fossil fuels. Thermochemical conversion of biomass is a common approach for biomass utilization with a relatively short conversion time. LÄS MER

5. 19. Bio-SNG from Thermal Gasification - Process Synthesis, Integration and Performance

   Författare :Stefan Heyne; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; process modelling; performance indicators; biomass; energy systems; synthetic natural gas; gasification;

   Sammanfattning : Biomethane or synthetic natural gas (Bio-SNG) produced from gasified renewable woody biomass is a promising option for replacing fossil natural gas. The complete interchangeability with natural gas in all its conventional applications such as in the power generation, transportation and chemical industry sector is of particular interest. LÄS MER
