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 toThe distributions of three-dimensional gas/particle velocity, particle volume flux, and particle sizeflux increased when the external secondary air volume increased.The size of the central reflux zone remained stable when the air volume ratio changed.This tertiary air was mixed with the peak value formed by the air in the adiabatic combustion chamber
