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

    Author : Rolf Christensen; Avdelningen för kemiteknik; []
    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.

  4. 2. Externally fired gas turbine cycle based on biomass gasification gas as fuel

    Author : Fabiola Baina Veizaga; Torsten Fransson; Lasse Rosendhal; KTH; []
    Keywords : Externally fired micro gas turbine; heat transfer; combustion of biomass derived gas; micro combined heat and power; Energiteknik; Energy Technology;

    Abstract : Energy services are essential for the development of societies, reduce poverty, and improve the living standards of inhabitants. The conventional routes to provide energy services employ fossil fuels. However, this involves environmental and availability concerns. READ MORE

  5. 3. Development of catalysts for natural gas-fired gas turbine combustors

    Author : Sara Eriksson; Magali Boutonnet; Pio Forzatti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AZEP; catalytic combustion; CPO; methane oxidation; palladium; rhodium; support effect; Chemical engineering; Kemiteknik;

    Abstract : Due to continuously stricter regulations regarding emissions from power generation processes, further development of existing gas turbine combustors is essential. A promising alternative to conventional flame combustion in gas turbines is catalytic combustion, which can result in ultralow emission levels of NOx, CO and unburned hydrocarbons. READ MORE

  7. 5. Integrating Biomass in Existing Natural Gas-Fired Power Plants

    Author : Erik Pihl; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forest Residue; Modeling; Hybrid Combined Cycles; Biomass; Gasification; Efficiency;

    Abstract : Using biomass for utility heat and electricity generation can supplement use of fossil fuels, whose emissions of carbon dioxide likely risk causing serious climate change and ocean acidification. Biomass as energy source is a limited resource and when used as fuel in thermal power plants this currently results in higher production costs than using fossil fuels such as natural gas and coal.
