The simultaneous measurement of OH-PLIF and Mie-scattering image of coal particles in a turbulent pulverized coal combustion flame is performed, and the spatial relation between the combustion reaction and the particle distribution is examined. The results show that in the upstream region, combustion reaction occurs only in the periphery of the clusters of coal particles where high-temperature burnt gas of the methane pilot flame is entrained and oxygen supply is sufficient, whereas it propagates inside of the clusters in the downstream region. This technique is effective for evaluating the combustion mechanism of the pulverized coal combustion flames and investigating their detailed flame structure.
