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.

Frontiers in Energy 2016, Volume 10, Issue 3,   Pages 337-346 doi: 10.1007/s11708-016-0401-2

Abstract: In this paper, an attempt is made to analyze computationally the effect of induction swirl in controllingengine, piston bowl geometry, exhaust gas recirculation (EGR) and equivalence ratio under different swirlThe results show that the swirl ratio has a considerable impact on controlling the peak pressures ofA reduction in peak pressures are observed with a swirl ratio of 4 because of reduced in cylinder temperaturesratios suggest that lower intake temperatures, reentrant piston bowl, higher engine speeds and higher swirl
