Claims

[Scope of utility model registration request]

A burner body in which a fuel passage for slurry fuel and a medium passage for a spray medium are formed independently, a fuel injection hole that communicates with the fuel passage, and a medium that communicates with the medium passage and merges into the fuel injection hole. A slurry fuel burner comprising: a mixing plate formed with ejection holes; and a spray plate formed with a mixed fuel ejection hole communicating with the fuel ejection hole and ejecting a mixed fuel of fuel and a spray medium,
One fuel passage is formed at the center of the burner body, a plurality of medium passages are formed at the periphery of the burner body, and the fuel injection holes are located at the center of the mixing plate, with an outlet side larger than an inlet side. A portion of the medium ejection hole, which is formed into a hole with a circular cross section and communicates with the plurality of medium passages individually, is communicated with the inlet of the fuel ejection hole, and the remaining medium ejection hole is connected with the outlet of the fuel ejection hole. The burner for slurry fuel is characterized in that the mixed fuel injection hole is formed in a central portion of the spray plate so as to be widened toward the outlet side, and the mixed fuel injection hole is formed in a central portion of the spray plate so as to communicate with each other in the surface line direction of the hole.
