1. Experimental and Theoretical Study of Rack Storage Fires
Sammanfattning : A theoretical and experimental study of rack storage fires and responsiveness of sprinklers is presented. Free-burn tests with non-combustible and combustible material were carried out in reduced scale with verification in large scale. LÄS MER
2. Fires in Narrow Construction Cavities : Fire Dynamics and Material Fire Performance
Sammanfattning : There have recently been devastating fire incidents related to fire spread over ventilated façades. These incidents indicate gaps in our understanding of the fire behaviour of façades. This thesis takes a bottom-up approach to investigating fire behaviour in materials and elements associated with narrow cavities in modern constructions. LÄS MER
3. Experimental studies of turbulent flames at gas turbine relevant burners and operating conditions
Sammanfattning : With the increasing demand of using alternative and renewable fuels, it becomes of vital importance to consider the fuel flexibility when designing a new burner for gas turbines. Hydrogen-enriched fuel and ammonia are two of these potential fuels, and they can significantly change the operability range of the gas turbines. LÄS MER
4. Experimental investigation of premixed ammonia combustion at high Karlovitz number conditions
Sammanfattning : This thesis aims to acquire deep knowledge on turbulent premixed combustion at high Karlovitz (Ka) number conditions with the help of laser-based diagnostic measurements.Considering that ammonia (NH3), as a carbon-free energy carrier, is a promising candidate for replacing conventional fossil fuels in the future, all the investigations in this work were carried out on ammonia/air premixed flames.

5. Entrained flow gasification of biomass: soot formation and flame stability
Sammanfattning : Entrained flow gasification (EFG) is a well-proven, commercially available technology for large scale coal gasification processes, with a production of a high quality syngas (a mixture of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4) and other compounds). For biomass, the process is still under development and there are several hurdles that must be cleared before it can become commercial. LÄS MER
