1. Chemical Properties of FBC Ashes
Sammanfattning : In this thesis several aspects of ash chemistry are discussed. An issue of primary concern for boiler operators is the formation of ash deposits. New biomass fuels are introduced, many of which have unfavourable ash melting behaviour due to high levels of alkali metal species and chlorine. LÄS MER
2. Oxide Formation and Degradation during Erosion-Corrosion of Iron and Nickel Based Alloys
Sammanfattning : Erosion-corrosion is, in many technical applications, a serious material degradation process caused by dynamic particle/fluid mixtures. Pipes transporting particle containing liquids, jet engines, gas turbines, and fluidised bed combustion (FBC) power plants are examples of systems which are considered to be especially susceptible.

3. Erosion - Corrosion Resistance and Adhesion of Laser and Thermally Deposited Coatings in Fluidised Beds
Sammanfattning : High temperature erosion - corrosion is the major source for degradation of components such as heat exchangers, tubes, cyclones and water walls used in Fluidised Bed Combustion (FBC) plants. By coating the exposed components with a protective material, the degradation rate can be decreased. LÄS MER
4. Gas quenching sampling system for measurements of volatile metals in FBC boilers : development and evaluation of the GQ probe by measurements of cadmium species in FBC flue gas
Sammanfattning : .... LÄS MER
5. Fluidized bed combustion - modeling and mixing
Sammanfattning : First demonstrated on industrial scale in 1976, fluidized bed combustion (FBC) rapidly became an established technology for solid fuel combustion with a currentinstalled capacity of about 30 GWe and power plants ranging from 10 to 460 MWe.The widespread use of the FBC technology both under so-called circulating and bubbling conditions (i.e. LÄS MER
