Predicting NOx Emissions from Wood Stoves using Detailed Chemistry and Computational Fluid Dynamics
The present paper addresses NOx emissions from wood stoves through a computational fluid dynamics (CFD) modeling approach. The most significant route for NOx formation in traditional biomass combustion applications is the fuel NOx mechanism. The formation of fuel NOx is very complex and sensitive to...
Numerical simulations of staged biomass grate fired combustion with an emphasis on NOx emissions
In the present paper NOx emissions from biomass combustion was studied, with the objective to demonstrate the applicability of stationary computational fluid dynamics simulations, including a detailed representation of the gas phase chemistry, to a multi-fuel lab-scale grate fired reactor using biom...
Fast Pyrolysis of Stem Wood in a Pilot-Scale Cyclone Reactor
Fast pyrolysis of stem wood was performed in a pilot-scale cyclone reactor with a reactor wall temperature of ∼750 °C. Wood powder was introduced to the pyrolyzer at 20 kg/h during the experiments. Stable operation of the pyrolyzer was easily achieved, and the resulting yields of the products were 5...
Evaluation of black liquor gasification intended for synthetic fuel or power production
The performance of a high-temperature pressurized black liquor gasifier intended for fuel or power production was evaluated both by thermochemical equilibrium calculations and with experiments performed in a development plant with a maximum capacity corresponding to 3 MWth. The aim of this paper was...
