Modeling of turbulent combustion including NO{sub x} chemistry. Modeling and reburning. Final report 1991-1993

Abstract

This report is the final report from the project ``Modeling and Reburning``. This project has been an cooperation between DTH - Denmark, Aabo akademi - Finland and SINTEF/NTH - Norway. The work has been financed by NGC and the work done at SINTEF/NTH has also been supported by the ``State Program for Utilisation of Natural Gas`` - SPUNG. The reburning process is a process for NO{sub x} reduction in the post flame region of combustion processes. It has been shown that in slightly rich mixtures of fuel, oxidizer and NO{sub x}, a reduction of NO{sub x} occurs. The reburning technique is mainly used in already existing furnaces where the NO{sub x} generated from fuel nitrogen can be reduced by injecting reburning fuel (typical methane) in the postflame region. If the reduction shall be efficient, the mixing of the reburning fuel with the flue gases from the primary combustion zone, must be good. Mathematical field modeling can be used to compute the mixing of reburning fuel with flue gases. In addition the degree of NO{sub x} reduction can be simulated if a turbulent combustion model and a model for NO{sub x} chemistry is implemented in a computer code for field modeling  More>>

This project has been an cooperation between DTH - Denmark, Aabo akademi - Finland and SINTEF/NTH - Norway. The work has been financed by NGC and the work done at SINTEF/NTH has also been supported by the ``State Program for Utilisation of Natural Gas`` - SPUNG. The reburning process is a process for NO{sub x} reduction in the post flame region of combustion processes. It has been shown that in slightly rich mixtures of fuel, oxidizer and NO{sub x}, a reduction of NO{sub x} occurs. The reburning technique is mainly used in already existing furnaces where the NO{sub x} generated from fuel nitrogen can be reduced by injecting reburning fuel (typical methane) in the postflame region. If the reduction shall be efficient, the mixing of the reburning fuel with the flue gases from the primary combustion zone, must be good. Mathematical field modeling can be used to compute the mixing of reburning fuel with flue gases. In addition the degree of NO{sub x} reduction can be simulated if a turbulent combustion model and a model for NO{sub x} chemistry is implemented in a computer code for field modeling of turbulent reacting flow. The aim of this project was to develop the models necessary to get a realistic description of the processes involved. In addition a simulator should be designed where the significant mathematical models are implemented. The reburning simulator is based on the KAMELEON-II computational fluid dynamic (CFD) code developed at SINTEF/NTH. The reburning simulator is called KAMELEON-REBURNING. (EG) (47 refs.)}
