Influence of mass air flow ratio on gas-particle flow characteristics of a swirl burner in a 29 MW pulverized

Rong YAN, Zhichao CHEN, Shuo GUAN, Zhengqi LI

Frontiers in Energy 2021, Volume 15, Issue 1,   Pages 68-77 doi: 10.1007/s11708-020-0697-9

Abstract: In a gas/particle two-phase test facility, a three-component particle-dynamics anemometer was used to measure the characteristics of gas/particle two-phase flows in a 29 megawatt (MW) pulverized coal industrial boiler equipped with a new type of swirling pulverized coal burner. The distributions of three-dimensional gas/particle velocity, particle volume flux, and particle size distribution were measured under different working conditions. The mean axial velocity and the particle volume flux in the central region of the burner outlet were found to be negative. This indicated that a central recirculation zone was formed in the center of the burner. In the central recirculation zone, the absolute value of the mean axial velocity and the particle volume flux increased when the external secondary air volume increased. The size of the central reflux zone remained stable when the air volume ratio changed. Along the direction of the jet, the peak value formed by the tertiary air gradually moved toward the center of the burner. This tertiary air was mixed with the peak value formed by the air in the adiabatic combustion chamber after the cross-section of / = 0.7. Large particles were concentrated near the wall area, and the particle size in the recirculation zone was small.

Engineering doi: 10.1016/j.eng.2023.06.010

Abstract: However, current AOPs assisted by co-catalysts still suffer from the poor mass/electron transfer andfluid dynamics simulations demonstrate that the optimal utilization of the 3D active area under the flow-throughmode, initiated by the convection-enhanced mass/charge transfer for Fe2+ reduction and thenstrengthened by MoS2-induced flow rotation for sufficient reactant mixing, is crucial forStrikingly, the flow-through co-catalytic system with superwetting capabilities can even tackle the intricate
