Combustion modelling opportunities and challenges for oxy-coal carbon capture technology
P.J. Edge,M. Gharebaghi,Robin Irons,R. Porter,Richard T.J. Porter,Mohamed Pourkashanian,D. Smith,Peter Stephenson,Alan Williams +8 more
TL;DR: A review of the opportunities and challenges surrounding the development of oxy-coal combustion models and discusses historical and recent advances in specific areas related to computational fluid dynamics (CFD), including char oxidation, radiation, pollutant formation and removal (Hg, NO x and SO x ), and the impact of turbulence as mentioned in this paper.

Large eddy simulations of coal gasification in an entrained flow gasifier
Neerav Abani,Ahmed F. Ghoniem +1 more
TL;DR: In this article, a coal-fed entrained flow gasifier was investigated using large-eddy simulations and Reynolds-averaged Navier Stokes models, where coal particles were modeled using a Lagrangian approach and the gas phase was solved using an Eulerian approach.
Journal ArticleDOI
Evaluation of solution methods for radiative heat transfer in gaseous oxy-fuel combustion environments
TL;DR: In this article, two principal methods, spherical harmonics (P1) and the discrete ordinates method (DOM), are used to calculate radiation properties of gases in combusting flows, and the radiative properties of the gases are calculated using a non-gray gas full spectrum k-distribution method and a gray method.
Journal ArticleDOI
Modelling methods for co-fired pulverised fuel furnaces
TL;DR: In this article, a co-firing of biomass and coal can be beneficial in reducing the carbon footprint of energy production, which is essential to discover potential problems that may occur during biomass firing and to mitigate potential negative effects of biomass fuels.
Journal ArticleDOI
Description, applications and numerical modelling of bubbling fluidized bed combustion in waste-to-energy plants
TL;DR: In this paper, the authors present a numerical model of a fluidized bed combustion of refuse-derived fuel (RDF) fed by RDF, where the combustor is divided into two regions: the bed and the freeboard.

Radiation heat transfer in combustion systems
R. Viskanta,M.P. Mengüç +1 more
TL;DR: In this paper, the authors present a review of the fundamentals of radiation heat transfer and some recent progress in its modeling in combustion systems. But, they do not consider the effects of radiation on the combustion process.

Transport-diffusion interfaces in radiative transfer
G.C Pomraning,G.M Foglesong +1 more
TL;DR: In this article, the Marshak boundary treatment is extended in a straight-forward way to give the connecting conditions at the diffusion-transport interface, and it is found that these conditions give a diffusion radiative flux from a blackbody in excess of the physical blackbody limit.
