1. Sulfur Capture and Oxidation of Calcium Sulfide in PFBC
Sammanfattning : Sorbents such as limestone are successfully used for removal of SO2 during pressurized fluidized bed combustion (PFBC) processes. However, there still remains a strong incentive to reduce the consumption of such sorbents. LÄS MER
2. The role of PDGF-B in brain blood vessels
Sammanfattning : The development of blood vessels is dependent on several molecular cues to form properly. A functional PDGF-B/PDGFR-b signaling is paramount for the investment of mural cells, that provide with support, to the developing vasculature. LÄS MER
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. 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
5. Availability Analysis of Three Different Types of Combined Cycle Power Plants
Sammanfattning : The goal of power plants with higher efficiency and lower environmental risk than conventional power plants has produced three types of combined cycle power plants. These are: 1) the conventional combined cycle (CCC) power plant, 2) the pressurised fluidised bed combustion (PFBC) power plants, and 3) the integrated gasification combined cycle (IGCC) power plants.
