1. Phosphorus recovery from sewage sludge fluidized bed gasification processes
Sammanfattning : One of the most sustainable pathways of sewage sludge treatment in recent years has been thermal conversion. The benefits of thermal treatment of sewage sludge are the recovery of energy or valuable chemical products, the destruction of harmful organic compounds, the separation of heavy metals from the P-rich coarse ash fraction, and the decreased and sanitized ash volume.

2. Reduction of the N2O Emission from Fluidized Bed Combustion by Afterburning
Sammanfattning : A method for reducing N2O emissions from fluidized bed combustion is presented and investigated. In contrast to flame combustion, fluidized bed combustion generates significant amounts of nitrous oxide (N2O) which are emitted to the atmosphere. LÄS MER
3. 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
4. Fluidized Bed Operating Parameters and Eulerian Erosion Models
Sammanfattning : A numerical two-fluid code, Gemini 2D, was adapted to study gas-solid fluidization in arbitrary 2D domains. The code was also used to study fluid dynamic mechanisms of dense particle flow that cause ductile and brittle erosion of solids. LÄS MER
5. Methanation of biosyngas in a fluidized bed reactor
Sammanfattning : Rising prices for fossil fuels and concerns over the climate change increase the interest in renewable energies. Synthetic natural gas (SNG) can be an option, filling the request for alternatives in the transportation sector, where the dependence on the oil is very strong. LÄS MER
