とを特徴とするスラリー燃料用バーナ。 A burner body in which a fuel passage for slurry fuel and a medium passage for a spray medium that atomizes the slurry fuel are formed independently, a fuel injection hole communicating with the fuel passage, and a fuel injection hole communicating with the medium passage, The mixing plate includes a mixing plate formed with a medium ejection hole that merges with the ejection hole, and a spray plate formed with a mixing chamber communicating with the fuel ejection hole and a plurality of mixed fuel ejection holes communicating with the mixing chamber. The burner for slurry fuel is characterized in that the opening area of the fuel nozzle is gradually expanded from the middle toward the spray plate side from the burner body, and the medium nozzle is merged into the part where the opening area is narrow. Burner for slurry fuel.
