36. Some Aspects of Gas Turbine Fuel Preparation and Turbomachinery Response to LCV Fuels
Sammanfattning : This thesis gives some background information on environmental issues as the scientific community at large currently sees it. It tries to relate the plethora of current combustion technologies which may be used in gas turbines to those issues. Some basic principles on combustion design are given. LÄS MER
37. Lean NOx reduction by alternative fuels - with focus on catalysts for dimethyl ether
Sammanfattning : There is an increased demand for diesel engines running on non-fossil fuels such as dimethyl ether (DME), biodiesel and synthetic diesel. DME is a promising alternative fuel with potential for high energy efficiency and low CO2 emissions. However, during all high temperature combustion NOx is formed, which may require exhaust aftertreatment. LÄS MER
38. Assessment of existing and potential developments of district-heating systems
Sammanfattning : District heating (DH) may play an important role for achieving the EU goal of a secure, competitive and sustainable energy supply. DH benefits from the possibilities of utilising local resources such as municipal solid waste and other low-quality fuels, as well as low-cost waste heat from industries and from combined heat and power plants (CHP).

40. Lignin Extraction from Black Liquor - Properties of the Liquors and Sulphur Content in the Lignin
Sammanfattning : Kraft lignin isolated by precipitation can be considered as being a valuable renewable source of energy and material. Removing lignin from black liquor is also advantageous as it decreases the load on the recovery boiler, which is usually the limiting factor in the production of kraft pulp. LÄS MER
