    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; flue systems; modelling; efficiency; condensing boilers; space heating; natural gas; Energiforskning;

    Abstract : Two main topics are dealt with in this thesis. Firstly, the performance of condensing boilers with finned tube heat exchangers and premix burners is evaluated. Secondly, ways of avoiding condensate formation in the flue system are evaluated. READ MORE

  3. 3. Modeling of Gas Flows in Steelmaking Decarburization Processes

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Zhili Jack Song; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOD; nozzle; jet; vacuum; BOF; LD; AOD; post combustion; flue; CFD;

    Abstract : The purpose of the current study is to increase the understanding of different steelmaking processes at the decarburization stages by use of mathematical modeling. More specifically, two De-Laval nozzles from a VOD (Vaccum Oxygen Decarburization) process, which is used for producing stainless steels with ultra-low carbon grades, was investigated for different vessel pressures.

  4. 4. Conceptual Thermodynamic Cycle and Aerodynamic Gas Turbine Design - on an Oxy-fuel Combined Cycle

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : ADRIAN NILSSON DAHLQVIST; Lund University.; Lunds universitet.; [2016-04-14]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas turbine; combined cycle; conceptual design; aerodynamic; mid-span design; through-flow design; oxy-fuel; SCOC-CC; OCC; gas turbine; Combined cycle; conceptual design; aerodynamic; mid-span design; Through-flow design; Oxy-fuel; SCOC-CC; OCC;

    Abstract : The world is today facing a serious problem with global warming, which is heading towards an appallingly high temperature level. The greater part of the overall climate science community agree that global warming is caused by the greenhouse effect, which depends largely on emitted CO2 emissions from the combustion of fossil fuel.

  5. 5. An Experimental and Theoretical Study of Decentralized Gas Fired Liquid Heating

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Rolf Christensen; Lund University.; Lunds universitet.; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid heating.; efficiency; environmental impact; emissions; corrugated tube; heat transfer augmentation; heat transfer enhancement; energy conservation; decentralized heating; Natural gas; steam replacement; gas firing; Carbochemistry; petrochemistry; fuels and explosives technology; Petrokemi; bränslen; sprängämnen;

    Abstract : 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.
