Direct numerical simulations (DNS) of a three-dimensional turbulent mixing layer are
performed, where coal particles seeded in an air stream mix with hot lean combustion …

Industrial pulverized coal boilers play an important role in the use of distributed energy, but
still suffer from severe pollutant emissions, combustion instabilities and poor fuel …

This study fundamentally investigates the effects of internal flue gas recirculation (IFGR) on
the combustion characteristics of methane/air mixtures, particularly on the NO x formation …

A numerical evaluation was performed to investigate the effects of swirl arrangement (co-
swirling and counter-swirling flows) and coal injection mode (non-, fully-, and partially …

Centrally staged swirl combustion can effectively reduce NO x emission. However, the
complex combustion field is susceptible to producing large-scale coherent structures, such …

Radial air staging is a new air staging method for industrial pulverized coal boilers. In this
paper, its impact on the gas-particle flow characteristics of industrial pulverized coal boilers …

Experimental investigations were conducted on the effect of the exhaust tube vortex (ETV)
and the synergistic effect of the ETV and air staging on nitrogen oxide (NO) concentration …

To ensure good combustion stability, industrial pulverized coal-fired boilers normally employ
a swirl burner with pre-combustion chamber (PCC). Owing to the high cross-sectional heat …

Abstract 3D measurements of burning coal particles in the flame are challenging and of
great interest. Digital inline holography is applied to perform 3D measurement of coal …

The paper reports on the results of experimental research of bidirectional vortex combustor
operation at different modes. This combustor implements a new idea of burning solid …
