Abstract
A method of ignition of a coal dust annular burner flame having an internal back flow region. The ignition energy is introduced centrally into the internal back flow region of the coal dust annular burner flame, and is delivered entirely or at least partially by a dust-ignition flame. The dust air-dust weight ratio for the dust-ignition flame is smaller than that of the main burner flame, being either 0.5 to 1.0, or 0.2 to 0.5, compared with a ratio of 1.5 to 2.0 for the main burner flame.
