Gasification of Biomass to Second Generation Biofuels: A Review
Biomass gasification has gained significant attention in the last couple of decades for the production of heat, power, and second generation biofuels. Biomass gasification processes are highly complex due to the large number of reactions involved in the overall process as well as the high sensitivit...
The effect of peat ash addition to demolition wood on the formation of alkali, lead and zinc compounds at staged combustion conditions
Combustion experiments were performed in a multi-fuel reactor with continuous feed of pellets by applying staged air combustion. Total characterization of the elemental composition of the fuel, the bottom ash and some particle size stages of fly ash was performed. This was done in order to follow th...
NOx emission reduction by staged combustion in grate combustion of biomass fuels and fuel mixtures
NOx and N2O emissions have been investigated for different pelletized biomass fuels and fuel mixtures thereof both with and without air staging in a grate fired multi-fuel reactor. The fuels investigated are wood, demolition wood and coffee waste, and selected mixtures of these. The multi-fuel react...
Ash related behaviour in staged and non-staged combustion of biomass fuels and fuel mixtures
The fate of selected elements (with focus on the important players in corrosion i.e. Na, K, Pb, Zn, Cl and S) are investigated for three biomasses (wood, demolition wood and coffee waste) and six mixtures of these as pellets both with and without air staging in a laboratory reactor. In order to get ...
The effect of kaolin on the combustion of demolition wood under well-controlled conditions
In an attempt to look at means for reduction of corrosion in boilers, combustion experiments are performed on demolition wood with kaolin as additive. The experiments were performed in a multi-fuel reactor with continuous feed of pellets and by applying staged air combustion. A total characterizatio...
Combustion Properties of Norwegian Biomass: Wood Chips and Forest Residues
Flue gas emissions and particle size distribution were investigated during combustion experiments of wood, forest residue and mixtures of these two. The combustion experiments were carried out in a grate fired multi-fuel reactor with and without air staging at stable operation conditions and constan...
