2. 1. Fouling in biomass fired boilers

   Author : Jan Sandberg; Rebei Bel Fdhila; Erik Dahlqvist; Anders Nordin; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fouling; deposit; boiler; biomass; simulations; Thermal energy engineering; Termisk energiteknik; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : In order to reduce the discharge of the greenhouse gas CO2, the use of biomass is nowadays promoted as fuel in boilers. Compared to boilers fired with coal and oil the biomass-fired boilers have more complications related to both fouling and corrosion on the heat transfer surfaces. READ MORE

4. 2. Modelling of Biomass Combustion in Furnaces

   Author : Torbern Klason; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; termodynamik; applied thermodynamics; grate fired boiler; Biomass combustion; computational analysis of boiler performance; Thermal engineering;

   Abstract : Biomass combustion in grate fired furnaces is an important approach to convert renewable biomass fuel to heat and electricity. It is not only used in the Swedish energy industry but also by a great number of Swedish households for domestic heating. Burning biomass has the advantage of being CO2 neutral. READ MORE

5. 3. 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.

6. 4. Integrating Biomass in Existing Natural Gas-Fired Power Plants

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

   Abstract : 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.

7. 5. High Temperature Corrosion of Superheaters in Biomass - and Waste-Fired Boilers: Combat on two fronts

   Author : Julien Phother Simon; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; KCl; Deposits; Waste; Oxidation; Biomass; Ni-based coatings;

   Abstract : Carbon dioxide is a greenhouse gas contributing to the greenhouse effect and a significant contribution comes from the use of fossil fuels. Utilizing more renewable fuels is therefore a solution to decrease the net release of CO2 emissions to the atmosphere. READ MORE
