Prediction of oxy-coal combustion through an optimized weighted sum of gray gases model

A full spectrum k-distribution based weighted-sum-of-gray-gases model for oxy-fuel combustion

“…The total mole fraction of CO 2 and H 2 O is equal 0.9 in the case with MR = 0.125, which refers to the dry recycle oxy-fuel conditions (case 1.1, 1.3, and 1.5). For MR = 1.0, the total mole fraction of CO 2 and H 2 O is set as 0.96 to represent the wet recycle oxy-fuel conditions (case 1.2, 1.4, and 1.6) [38].…”

New weighted-sum-of-gray-gases model for typical pressurized oxy-fuel conditions

“…Each condition also includes 2 flue gas recycles: wet and dry; thus, there are a total of 4 cases under every pressure condition. In this study, the cases were selected with reference to the experiment results given in and the cases presented in . The wall of the plate is a blackbody, ie, ε w = 1.…”

Radiative heat transfer in strongly forward scattering media of circulating fluidized bed combustors

“…This agreement may be attributed to low particle load (0.01 kg/ m 3 ) in the ABFBC under consideration. Use of isotropic scattering assumption in pulverized fuel (PF) furnaces with the same order of magnitude particle load [13,14] has also been found to lead to fairly accurate results, as reported in recent literature [15][16][17][18][19][20][21][22][23]. However, in some of these studies, isotropic scattering was found to underestimate wall heat fluxes, mostly due to fly ash [17], compared to measurements [18,19].…”
