  1. 1. Modelling of Biomass Combustion in Furnaces

    University dissertation from Lund University (Media-Tryck)

    Author : Torbern Klason; Lund University.; Lunds universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; termodynamik; applied thermodynamics; grate fired boiler; Biomass combustion; computational analysis of boiler performance; Thermal engineering;

    Abstract : Biomass combustion in grate fired furnaces is an important approach to convert renewable biomass fuel to heat and electricity. It is not only used in the Swedish energy industry but also by a great number of Swedish households for domestic heating. Burning biomass has the advantage of being CO2 neutral. READ MORE

  2. 2. On Radiative Heat Transfer Modeling with Relevance for Combustor and Biomass Furnaces

    University dissertation from Lund University (Media-Tryck)

    Author : Mehdi Bahador; Lund University.; Lunds universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; termodynamik; fluiddynamik; plasma; Thermal engineering; applied thermodynamics; Termisk teknik; plasmas; Gaser; Thermal Radiation; Scattering; Heat load; Gases; fluid dynamics; Biomass Furnaces; framdrivningssystem; Motorer; Motors and propulsion systems;

    Abstract : Thermal radiation sometimes is the dominating heat transfer mode in combustion chambers and furnaces and therefore in the design of many relevant industrial facilities prediction of it is necessary. During previous years many research efforts in the radiative heat transfer field have originated and many methods and models from simple to complex have been developed. READ MORE

  3. 3. Advanced Gasification of Biomass/Waste for Substitution of Fossil Fuels in Steel Industry Heat Treatment Furnaces

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Duleeka Gunarathne; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pretreatment; Gasification; Pressure drop; Steel industry; Fuel switch; Energy efficiency; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : With the current trend of CO2 mitigation in process industries, the primary goal of this thesis is to promote biomass as an energy and reduction agent source to substitute fossil sources in the steel industry. The criteria for this substitution are that the steel process retains the same function and the integrated energy efficiency is as high as possible. READ MORE

  4. 4. Ash Behavior in Fluidized-Bed Combustion and Gasification of Biomass and Waste Fuels Experimental and Modeling Approach

    University dissertation from Borås : Högskolan i Borås

    Author : Farzad Moradian; Högskolan i Borås.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluidized-bed; combustion; gasification; waste-derived fuels; biomass; ash-related problems; deposit; fouling; slagging; bed agglomeration; thermodynamic equilibrium modeling;

    Abstract : Over the past few decades, a growing interest in the thermal conversion of alternative fuels such as biomass and waste-derived fuels has been observed among the energy-producing companies. Apart from meeting the increasing demand for sustainable heat and power production, other advantages such as reducing global warming and ameliorating landfilling issues have been identified.

  5. 5. Pyrolysis of biomass in fluidized-beds: in-situ formation of products and their applications for ironmaking

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Pelle Mellin; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pyrolysis; Fluidized bed; CFD; Blast furnace; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The iron and steel industry emitted 8 % of all CO2 emissions in Sweden, 2011. Investigating alternative energy carriers is the purpose of this thesis. By pyrolyzing biomass, an energetic solid, gaseous and liquid (bio oil) fraction is obtained. READ MORE
