   Abstract : Gas turbines, in simple and combined cycle, are common and economically profitable on the power generating market today. Several new cycles have been proposed as future competing technologies, but all studies about these cycles have, so far, been paperwork. READ MORE

4. 2. Some Aspects of Gas Turbine Fuel Preparation and Turbomachinery Response to LCV Fuels

   Author : Pontus Eriksson; Kraftverksteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PDA; LDA; PIV; atomization; spray; off-design; biogas; combustor; biofuel; turbine; Gas turbine; compressor;

   Abstract : 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. READ MORE

5. 3. Humidification Processes in Gas Turbine Cycles
