Impacts of Torrefaction on PM10 Emissions from Biomass Combustion

Impacts of Combustion Conditions and Photochemical Processing on the Light Absorption of Biomass Combustion Aerosol.

The aim was to identify relationships between combustion conditions, particle characteristics, and optical properties of fresh and photochemically processed emissions from biomass combustion. The combustion conditions included nominal and high burn rate operation and individual combustion phases from a conventional wood stove. Low temperature pyrolysis upon fuel addition resulted in "tar-ball" ...

Torrefaction Kinetics of Norwegian Biomass Fuels

Torrefaction kinetics of Norwegian biomass fuels, including spruce (softwood) and birch (hardwood) was studied using a thermogravimetric analyser. Small samples of approximately 10 mg and particle size of 63−125 μm were heated at a constant heating rate of 5 °C/min and kept afterwards for 4 hours in isothermal conditions at different temperatures (230, 240, 250, 260, 270 and 280 °C). A two-step...

Effect of Torrefaction Process Parameters on Biomass Feedstock Upgrading

Biomass is a primary source of renewable carbon that can be utilized as a feedstock for biofuels or biochemicals production in order to achieve energy independence of energy importing countries. The low bulk density, high moisture content, degradation during the storage, and low energy density of raw lignocellulosic biomass are all significant challenges in supplying agricultural residues as a ...

Development of reduced mechanisms applicable to CFD modeling of NOx emissions from biomass combustion

i Preface The report deals with development of reduced kinetic mechanisms for ammonia oxidation that can be used for CFD modeling of NO x formation in biomass combustors. A computer code CARM was tested for generation of the reduced mechanisms. Berkeley. We want to thank him for supplying us with the code, as well as helping us to get started. The report firstly describes shortly the general me...
