1. 1. Modelling of Biomass Combustion in Furnaces

   Författare :Torbern Klason; Strömningsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; termodynamik; applied thermodynamics; grate fired boiler; Biomass combustion; computational analysis of boiler performance; Thermal engineering;

   Sammanfattning : 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. LÄS MER

3. 2. Detecting, Modelling and Measuring Disturbances in Fixed-bed Combustion

   Författare :Sven Hermansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD modelling; solid fuels; grate furnaces; moisture content; fixed bed; combustion;

   Sammanfattning : Combustion of fixed fuel beds in grate furnaces is one of the most common techniques within production of heat and power from solid fuels. The grate furnace used to be a working horse for combustion of hard coal, while today the incitement of using renewable fuel sources has turned biomass and municipal waste into dominating fuel types.

4. 3. Modelling and Experimental Investigations on Thermal Radiation in Combustion Environments

   Författare :Henrik Hofgren; Värmeöverföring; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal radiation; Property model; SNB; WSGG; LBL; Planck; particle; fly-ash; soot; grate; furnace; combustion;

   Sammanfattning : Thermal radiation is an important physical phenomenon in combustion environments. For the understanding of existing- and the design of new combustion environments computational modelling is a useful tool as it can describe the different transport phenomena. LÄS MER

5. 4. Characterization of conversion zones in a reciprocating grate furnace firing wet woody biomass

   Författare :Narges Razmjoo; Strand Michael; Chungen Yin; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass combustion; Grate firing; Fuel bed; Moisture; Gas phase; Conversion zone; Experimental; Temperature distribution; Gas analysis; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

   Sammanfattning : Grate-firing systems are a common and popular combustion technology for burning biomass. However, combustion of biomass in these furnaces may emit a large amount of pollutants in the form of CO, CH4, PAH, NOx, and particles. LÄS MER

7. 5. Design of advanced industrial furnaces using numerical modeling method

   Författare :Wei Dong; KTH; []
   Nyckelord :;

   Sammanfattning : This doctoral thesis describes the fundamentals ofmathematical modeling for the industrial furnaces and boilersand presents the results from the numerical simulations of sometypical applications in advanced industrial furnaces andboilers. The main objective of this thesis work is to employcomputational fluid dynamics (CFD) technology as an effectivecomputer simulation tool to study and develop the newcombustion concepts, phenomena and processes in advancedindustrial furnaces and boilers.
