1. Energilandskap i förändring : Inramningar av kontroversiella lokaliseringar på norra Gotland
Sammanfattning : Energisystemet omstruktureras. Nya energikällor tillkommer och andra fasas ut samtidigt som efterfrågan på energi kvarstår ur ett globalt perspektiv. LÄS MER
2. Improved Energy Efficiency and Fuel Substitution in the Iron and Steel Industry
Sammanfattning : IPCC reported in its climate change report 2013 that the atmospheric concentrations of the greenhouse gases (GHG) carbon dioxide (CO2), methane, and nitrous oxide now have reached the highest levels in the past 800,000 years. CO2 concentration has increased by 40% since pre-industrial times and the primary source is fossil fuel combustion. LÄS MER
3. Determining the quality of natural gas and biomethane : Development of a correlative method and instrument prototype for measuring gas quality
Sammanfattning : The composition of natural gas highly depends on its origin: natural gas from various deposits, substitute natural gas that can be produced from fossil fuels or renewable sources. The intermixing of gases from various supply sources during pipeline transportation also leads to more complicated and unpredictable gas composition variations at the consumption site. LÄS MER
4. BlueBellMouse. A Tool for Kinetic Model Development
Sammanfattning : The simulation of physical phenomena occurring in chemical reactors requires the description of the kinetics involved in the underlying combustion process. Kinetic models are developed for this purpose. LÄS MER
5. Investigation of a prototype industrial gas turbine combustor using alternative gaseous fuels
Sammanfattning : In this thesis, the effect of alternative gaseous fuels, with high hydrogen content and lower calorific value, on gas turbine combustion was investigated experimentally. The aim of the investigation was to find operational limitations for an experimental burner and to supply data for validation of computational fluid dynamics (CFD). LÄS MER
