“…Many experimental studies in the literature [1][2][3] on the characteristics of high temperature diluted air combustion showed that it yields very low NO x emission, low luminosity, higher flame stability, large flame volume and a more uniform temperature field. The literature on the computational side of the study is also extensive: Yuan and Naruse [4] obtained the combustion characteristics of a cross-jet flame with highly preheated diluted air, which were in line with those of experiment, by using a PDF/mixture fraction model with equilibrium chemistry.…”

“…They found that the MILD combustion process of light oil was similar to that of natural gas to a great deal while the MILD combustions of heavy fuel oil and coal were significantly different always with visible flames. Lille et al [4] experimentally studied HiTAC combustion of a single fuel jet of Gasol (> 95% of propane). Their studies revealed that the combustion of Gasol in hot and oxygen depleted flue gases appeared to be so stable and complete.…”

This paper employs large eddy simulation (LES) to investigate non-premixed flameless oxidation occurring in the IFRF furnace with varying fuel-injection angle. In order to model radiation and combustion using OpenFOAM software, finite volume discrete ordinate model and partially stirred reactor are applied whereas the detailed mechanism GRI-2.11 is undertaken represent chemistry reactions. The obtained results are compared with the experimental measurements of Mancini's et al. After ensuring the accuracy of the LES method, the combustion characteristics are examined when using different fuel injection angles into the combustion chamber. The results explain using fuel injection with an angle into the combustion chamber, the net rate of reaction and entropy generation increases.

“…The HiCOT can achieve higher combustion efficiency [8] with lower oxygen concentration [9] because of its high air temperature. Thus, the HiCOT can reduce the amount of soot produced in the system [10]. Moreover, the HiCOT can improve the performance of an industrial furnace because its uniform temperature distribution around the flame lowers NO x emissions [11,12].…”

In order to investigate the effect of buoyancy on soot formation in gas-jet diffusion flame, we conducted one set of experiments with the High-Temperature Air Combustion Technology (HiCOT) system and another set under partial gravity conditions. Ethylene (C 2 H 4 ) was used as fuel, and soot volume fractions for the flame were observed as shadow graph images with backlight. In the experiment with the HiCOT, the oxygen concentrations were O 2 = 15 %, 17 %, and 23 %, with constant flame temperature and surrounding air temperatures of 1100 K, 900 K, and 300 K, respectively. We found that the soot volume fraction in the flames increased with the increase of the oxidizer temperature. In the partial gravity experiment meant to identify the buoyant effect, the results showed that the soot volume fraction depended on the gravity level. These results imply that soot formation in a gas-jet diffusion flame with the HiCOT is strongly affected by the buoyant flow due to oxidizer flow into the soot formation field.
