NO Emission Behavior in Oxy-fuel Combustion Recirculated with Carbon Dioxide
Jeong Park,June Sung Park,Hyun Pyo Kim,Jeong Soo Kim,Sung Cho Kim,Jong Geun Choi,Han Chang Cho,Kil Won Cho,Heung Soo Park +8 more
TL;DR: In this article, a numerical study was conducted to grasp the flame structure and NO emissions for a wide range of oxy-fuel combustion (covering from air-blown combustion to pure oxygen combustion) and various mole fractions of recirculated CO2 in a CH4−O2/N2/CO2 counterflow diffusion flame.
Journal ArticleDOI
Flame characteristics in H2/CO synthetic gas diffusion flames diluted with CO2: Effects of radiative heat loss and mixture composition
Jeong Park,Dae Seok Bae,Min Seok Cha,Jin Han Yun,Sang In Keel,Han Chang Cho,Tae Kwon Kim,Ji-Soo Ha +7 more
TL;DR: In this article, Sun et al. evaluated the impact of fuel composition and flame radiation in flame structure and their oxidation process in H2/CO synthetic gas diffusion flame with and without CO2 dilution.
Journal ArticleDOI
Unsteady thermal flow analysis in a heat regenerator with spherical particles
TL;DR: In this paper, the regenerative particle experiences small temperature fluctuation below 10 K during the reversing process and it is confirmed that inlet Reynolds number of exhaust gases should be introduced as a regenerator design parameter.
Journal ArticleDOI
Hydrogen utilization as a fuel: hydrogen‐blending effects in flame structure and NO emission behaviour of CH4–air flame
Jeong Park,Dong-Jin Hwang,June Sung Park,Jeong Soo Kim,Sang In Keel,Han Chang Cho,Dong Soon Noh,Tae Kwon Kim +7 more
TL;DR: In this paper, the effects of hydrogen-blending on flame structure and NO emission behavior are numerically studied with detailed chemistry in methane-air counterflow diffusion flames, where the composition of fuel is systematically changed from pure methane to the blending fuel of methane-hydrogen through H2 molar addition up to 30%.
Journal ArticleDOI
Effect of coal type on gasification in pressurized drop tube furnace
TL;DR: In this article, the effect of coal type on coal gasification process at 15 atmospheric pressure of pressurized drop tube furnace (PDTF), a numerical study was conducted, where the Eulerian approach was used for the gas phase, whereas Lagrangian approach is used for solid phase.
