摘要：

Based on experimental research and numerical simulation, the influence of wall temperature on multi-stage pulverized coal (PC) ignition was studied. The results of numerical calculation are fairly consistent with those of experiment. In multi-stage PC ignition, the flue gas of the first stage ignition is reductive, exorbitant temperature does not help the ignition of the second stage PC air mixture.
