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

2. Study of the Apparent Kinetics of Biomass Gasification Using High-Temperature Steam
Sammanfattning : Among the latest achievements in gasification technology, one may list the development of a method to preheat gasification agents using switched ceramic honey combs. The best output from this technology is achieved with use of water steam as a gasification agent, which is heated up to 1600 °C. LÄS MER
3. Refractory corrosion in biomass gasification
Sammanfattning : To stop the net emission of CO2 to the atmosphere, we need to reduce our dependency of fossil fuels. Although a switch to a bio-based feedstock hardly can replace the total amount of fossils used today, utilization of biomass does still have a role in a future in combination with other techniques.

4. Black liquor gasification : experimental stability studies of smelt components and refractory lining
Sammanfattning : Black liquors are presently combusted in recovery boilers where the inorganic cooking chemicals are recovered and the energy in the organic material is converted to steam and electricity. A new technology, developed by Chemrec AB, is black liquor gasification (BLG). LÄS MER
5. Pressurized entrained-flow high temperature black liquor gasification : CFD based reactor scale-up method and spray burner characterization
Sammanfattning : Black liquor is an important by-product in the chemical kraft pulping process, which provides the paper mill with pulp. Due to both economical and environmental protection driving forces it is important to recover the pulping chemicals and energy contained in the black liquor. LÄS MER
