2. 1. 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

4. 2. Development of LPP-Burner for Industrial Gas Turbine Application

   Author : Jonas Holmborn; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; Dry Low Emission DLE ; Lean Partially Premix LPP ; Combustion; Gas Turbine; Burner; applied thermodynamics; Termisk teknik; termodynamik;

   Abstract : This thesis reports the work done in the development of a modified Lean Premix Prevaporised (LPP) burner for the use in Alstom Power Sweden’s industrial gas turbines. Incentive for the development of the modified burner have been the need to increase the flame stability over the operating range for the burner, especially for the liquid fuel but also the gaseous fuel operation.

5. 3. Investigation of a prototype industrial gas turbine combustor using alternative gaseous fuels

   Author : Ivan Sigfrid; Kraftverksteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; Gas Turbine; Laminar flame speed; Stretch; Lean blowout; Emissions;

   Abstract : 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). READ MORE

6. 4. Experimental investigation of flows related to gas turbine combustion

   Author : Dragan Stankovic; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; combusiton; flameless; jets in cross flow; chemiluminescence; POD; LIF; PIV; Spray; Gas Turbine; single digit NOx; Premixed Combustion; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

   Abstract : The notion of "global warming" has become a major public-domain concept as an environmental threat to our future on earth. Independently of the accuracy of existing prediction of combustion emissions on the climate on earth, the concept of reducing combustion emissions has been an important political driving force in imposing more and more severe restrictions on harmful emissions from combustion.

7. 5. Aspects of creep-fatigue in gas turbine hot parts

   Author : Magnus Hasselqvist; Gunnar Härkegård; Linköpings universitet; []
   Keywords : creep; fatigue; TMF; gas turbine; modelling; life assessment; ageing; micro-structure; solute drag; back stress; Haynes 230; IN792;

   Abstract : The goal is reliable creep-fatigue lifing methodology for industrial gas turbines.A literature study on high temperature materials used in gas turbines reveals that:• Most testing/modelling work has focused on characterisation and modelling of material response in isothermal standard tests, i.e. creep, tensile and LCF tests.
