6. Evaluation, Experience and Potential of Gas Turbine Based Cycles with Humidification
Sammanfattning : 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. LÄS MER
7. Bimetallic palladium catalysts for catalytic combustion of methane
Sammanfattning : Catalytic combustion is a promising combustion technique in gas turbines, which results in ultra low levels of NOx, CO and unburned hydrocarbons. Due to the low combustion temperature achieved in catalytic combustion almost no thermal NOx is formed. The focus in this thesis will be on the first stage in a catalytic combustion chamber, i.e. LÄS MER
8. An Experimental and Theoretical Study of Decentralized Gas Fired Liquid Heating
Sammanfattning : The effects on the energy situation in industry when gas fired liquid heaters replace steam have been determined by energy surveys performed in a brewery and a slaughterhouse, measurements of the performance and emissions from liquid heaters installed in these industries, and theoretical analyses of the potential energy saving. The theoretical study in the first part of the project provides information that allows assessment of the effects on the energy situation, of part or complete conversion to decentralized heating, under the conditions prevailing in the industries concerned.

9. Experimental studies of turbulent flames at gas turbine relevant burners and operating conditions
Sammanfattning : With the increasing demand of using alternative and renewable fuels, it becomes of vital importance to consider the fuel flexibility when designing a new burner for gas turbines. Hydrogen-enriched fuel and ammonia are two of these potential fuels, and they can significantly change the operability range of the gas turbines. LÄS MER
10. Application of Laser-based Diagnostics to a Prototype Gas Turbine Burner at Selected Pressures
Sammanfattning : The matured laser-diagnostic techniques of planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) were applied to a prototype gas turbine burner operating on various fuels. The work was performed to provide verification of computational fluid dynamic (CFD) models of the combustion of atypical fuels in a gas turbine combustor. LÄS MER
