2. 1. Modelling of Biomass Combustion in Furnaces

   Author : Torbern Klason; Strömningsteknik; []
   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

4. 2. Design of advanced industrial furnaces using numerical modeling method

   Author : Wei Dong; KTH; []
   Keywords : ;

   Abstract : 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.

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

   Author : Farzad Moradian; Högskolan i Borås; []
   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.

6. 4. High temperature corrosion during waste incineration : characterisation, causes and prevention of chlorine-induced corrosion

   Author : Peter Viklund; Christofer Leygraf; Jan Froitzheim; Staffan Hertzman; Sweden Stockholm Swerea KIMAB AB; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; high temperature corrosion; waste incineration; superheater tubing; steel; alkali; chlorine; suphur; Chemistry; Kemi;

   Abstract : Waste-fired boilers suffer severely from corrosion of critical components such as superheater tubes. In this work the high temperature corrosion of candidate superheater alloys have been investigated by detailed laboratory studies and controlled field exposures in full-scale boilers. READ MORE

7. 5. Particles from biomass combustion -Characteristics and influence of additives

   Author : Linda S Bäfver; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; particle emission; wood; biomass; cereals; wood pellets;

   Abstract : AbstractHigh particle concentration in the air is a health risk, and particles from domestic biomass combustion are a significant particle source. In larger boilers, particles are an important element in the build-up of deposits on heat transfer surfaces, causing increased operation and maintenance costs. READ MORE
