| Abstract: | ased on a mathematical model developed by the authors, numerical simulation has beenmade for the ignition and flame stability of pulverized coal in a single pulverized coal furnace.Numerical simulation results of a straight-flow burner, bluff-body and slit bluff-body burn-ers are given. For a straight-flow burner with a rectangular section, a series of factors af-fecting the coal ignition and flame stability have been investigated. |
