  1. 1. Characterization of mineral parageneses and metamorphic textures in eclogite- to high-pressure granulite-facies marble at Allmenningen, Roan, western Norway

    University essay from Lunds universitet/Geologiska institutionen

    Author : Stylianos Karastergios; [2020]
    Keywords : Western Gneiss Region; Vestranden; Roan; Caledonides; marble; calc-silicate; metabasic; petrography; SEM-EDS; mineral chemistry; mineral equilibrium; P–T estimate; devolatilization; Earth and Environmental Sciences;

    Abstract : The Roan peninsula in western Norway, Vestranden, is known for exposing one of the deepest parts of the Scandinavian Caledonian orogen, similar to the Western Gneiss Region. Throughout the Roan area, eclogites and high-pressure granulite- and amphibolite-facies gneisses occur, associated with supracrustal rocks including marbles, calc-silicate rocks and amphibolites.

  3. 2. Simultaneous detection of potassium, water vapor and temperature with tunable diode laser absorption spectroscopy

    University essay from Umeå universitet/Institutionen för fysik

    Author : Edvin Norén; [2015]
    Keywords : TDLAS; DAS; WMS; Simultaneous detection; Measurement; Potassium; Water vapor; Temperature; Biomass; Optics;

    Abstract : Existing tunable diode laser absorption spectroscopy (TDLAS) sensors for potassium (K) and for water vapor (H2O) and temperature were combined to enable simultaneous measurements in combustion and gasification processes. In-situ real-time detection of the above mentioned combustion parameters will improve the understanding of ash-formation during thermochemical conversion of biomass. READ MORE

  4. 3. Computational fluid dynamics (CFD) study of co-firing of coal and pretreated biomass

    University essay from KTH/Energi- och ugnsteknik

    Author : A S M Abdul Hye; [2014]
    Keywords : Computation fluid dynamics; co-firing; emission; boiler; coal; biomass; torrefied biomass;

    Abstract : This master thesis describes the co-firing concept, benefits and opportunities of pretreated biomass in pulverized coal boilers for industrial use. Burning fossil fuels, i.e. coal is under immense political pressure as European Union (EU) and other countries are trying to bring down the CO2 emission. READ MORE

  5. 4. Combustion characteristics of steam-exploded biomass pellets

    University essay from KTH/Energi- och ugnsteknik

    Author : Maria Gabriela Ponce Valle; [2011]
    Keywords : biomass combustion; pretreatment; steam-exploded pellets;

    Abstract : Currently pelletized woody biomass is widely used as a fuel in thermal applications toaccelerate the global transition to renewable energy. Fuel upgrade is one of the key factorsto improve energy conversion processes. Woody biomass can be fractionated into its mainconstituents by steam explosion. READ MORE
