2. 6. Effects of Varying Combustion Conditions on PCDD/F Formation

   Author : Johanna Aurell; Stellan Marklund; Sukh Sidhu; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; dioxin; formation; PCDD; PCDF; MSW incineration; transient combustion; sulfur; memory effects; quench time; chlorine; combustion; polychlorinated dibenzothiophenes; NO; water; Environmental chemistry; Miljökemi;

   Abstract : Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are by-products emitted from combustion sources such as municipal solid waste (MSW) incineration plants. These organic compounds are recognized as toxic, bioaccumulative and persistent in the environment. READ MORE

4. 7. Disturbances in Fixed-Bed Combustion

   Author : Sven Hermansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; modelling; packed bed; bed; combustion; channelling; grate furnace;

   Abstract : Conversion of solid fuels in fixed beds is a common method for heat and power production. A frequent fixed-bed technique in small to medium scale is combustion in grate furnaces. Grate furnaces are widely used in the industrial energy branch and appreciated for their stability and simplicity of control. READ MORE

5. 8. Investigation of Emission Characteristics for Diluted Flames and Renewable Fuels in Gas Turbine Combustors

   Author : Fredrik Hermann; Kraftverksteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; framdrivningssystem; Motorer; termodynamik; Motors and propulsion systems; Termisk teknik; applied thermodynamics; Thermal engineering; combustor rig experiments; combustor reactor models; synthetic fuel; liquid fuel; gaseous fuel; UHC; CO; NOx; emission measurements; CO2 enriched; humidified combustion; diluted combustion; premixed combustion; Gas turbine; combustion chamber; Energiforskning; Energy research;

   Abstract : Gas turbines have served as economically profitable and reliable generators of power for the past few decades, and have mainly been used in simple and combined cycles. The increased restrictions on hazardous emissions and the increased demand for profitability have created new prospects for innovative power cycles. READ MORE

6. 9. Design and Optimization of In-Cycle Closed-Loop Combustion Control with Multiple Injections

   Author : Carlos Jorques Moreno; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Combustion; Pilot-Main Injection; Pilot Mass Estimation; Cylinder Volume Estimation; Bayesian Estimation; In-Cycle Combustion Controllability; In-Cycle Combustion Control; Model Predictive Combustion Control; Stochastic Combustion Optimization; Hardware Quantification;

   Abstract : With the increasing demand of transportation, biofuels play a fundamental role in the transition to sustainable powertrains. For the increased uncertainty of biofuel combustion properties, advanced combustion control systems have the potential to operate the engine with high flexibility while maintaining a high efficiency and robustness.

7. 10. Characterization of an Electrical Sensor for Combustion Diagnostics

   Author : Axel Franke; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ion sensor; combustion; nitric oxide; chemi-ionization; equilibrium; Physics; ionized gases; Fysicumarkivet A:2002:Franke; ionization sensor; Fysik;

   Abstract : The ionization sensor is an electrical probe for diagnostics in internal combustion engines. The combustion process affects the electrical properties of the gas in the cylinder. Thus the sensor signal contains copious information about the conditions in the combustion chamber. READ MORE
