On a self-built flat flame entrained flow reactor system experimental apparatus
which the temperature can reach 1 750 Kand the heat rate can reach 105 to 106 K/s
experimental study on ignition delay performance of pulverized coal was carried out.Through image acquisition system
the instantaneous image of pulverized coal combustion was obtained
and the variations of the luminous intensity of the pulverized coal were obtained from post processing of the instantaneous images.The results show that
the luminous intensity curves of all kinds of pulverized coal had similar trends
and there was a maximum value of light intensity in each curve.The XINYI(XY)coal had the shortest ignition delay time while the YAXI2(YX2)coal had the longest.This experimental result can provide references for burner design in pulverized coal boilers.
