Abstract (en)
[origin: US2009038518A1] A plasma ignition burner. The plasma ignition burner has at least two stages of burner barrels and a plasma generator for igniting the pulverized coal in a first stage burner barrel of the at least two stages of burner barrels. The burning flame of the former stage burner barrel ignites the pulverized coal in the next stage burner barrel, or further burns with the supplemented air in the next stage burner barrel. The axial direction of said plasma generator is parallel to the direction along which the pulverized-coal-contained air flow enters into the first stage burner barrel and at the same time, parallel to the axis of the burner barrels.
