| Abstract: | With the development of the bluff-body burner for low-grade pulverized coal, many experiments have been carried out with a single burner furnace. The cold-state velocity field and hot-state temperature field have been measured. The results obtained show that the use of a bluff-body burner makes it easier to ignite coal, stabilizes and intensifies flame. On the basis of the experiments, the mechanism of flame stabilization of pulverized coal with a bluff-body burner is studied. Suggestions for further investigations and burner development have been made. |
