6. Advanced power cycles with mixture as the working fluid
Sammanfattning : The world demand for electrical power increasescontinuously, requiring efficient and low-cost methods forpower generation. This thesis investigates two advanced powercycles with mixtures as the working fluid: the Kalina cycle,alternatively called the ammonia-water cycle, and theevaporative gas turbine cycle. LÄS MER
7. Climate impact of the sustainable use of forest biomass in energy and material system : a life cycle perspective
Sammanfattning : Human society releases greenhouse gas emissions to the atmosphere while providing housing, heat, mobility and industrial production. Man-made greenhouse gas emissions are the main causes of climate change, coming mainly from burning fossil fuels and land-use changes. LÄS MER
8. Analyzing technological change using experience curves - a study of the combined cycle gas turbine
Sammanfattning : The aim of this thesis was to analyze and discuss the use of experience curves as a possible instrument for assessing future developments of a specific energy technology: the combined cycle gas turbine (CCGT). The CCGT technology is expected to figure prominently in future energy systems. LÄS MER
9. Forest-Fuel Systems : Comparative Analyses in a Life Cycle Perspective
Sammanfattning : Forest fuels can be recovered, stored and handled in several ways and these different ways have different implications for CO2 emissions. In this thesis, comparative analyses were made on different forest-fuel systems. The analyses focused on the recovery and transport systems. LÄS MER
10. Modern Thermal Power Plants - Aspects on Modelling and Evaluation
Sammanfattning : The European Union (EU) has laid down very clear objectives for the reduction of greenhouse gases in the hope that it will prevent or mitigate climate change. Political incentives are used to make the power industry adopt changes in order to reach these EU targets. LÄS MER
