PROBLEM TO BE SOLVED: To provide a ceramic burner which is durable against the operation for a long time. SOLUTION: The inner surface 4 of an inner cylinder at the downstream side at a high temperature part is formed of a composite reinforcing material obtained by compositely reinforcing oxide ceramics by SiC whisker, and the inner surface 5 of the inner cylinder at the upstream side at a low temperature part is formed of non-oxide ceramics, and hence the surface 4 of the cylinder at the downstream side secures strength together with oxidation resistance. Since the surface 5 at the upstream side can avoid the damage due to the excess thermal stress generated due to the local temperature difference produced at the part, the burner can be continuously operated at a high temperature for a long time, thereby making it possible to largely improve the reliability of a gas turbine. |
