Abstract:
To accurately position an electrode for ignition or flame detection of a combustion burner, to the combustion burner.SOLUTION: A combustion device 100 includes a burner unit, a burner case, a combustion chamber front plate 30 forming a combustion chamber C with the burner case, a sparker electrode 40, an insulator member 50 holding the sparker electrode 40, and a pressing plate 80 for mounting the insulator member 50 on the combustion chamber front plate 30. The combustion chamber front plate 30 has a mounting surface 31, a bottom surface having an insertion hole 32a to which the sparker electrode 40 and the insulator member 50 are inserted, and first inclination portions 33a, 33b connecting the mounting surface 31 and the bottom surface. The insulator member 50 has a tip portion 51 inserted to the insertion hole 32a, and a projection portion 52 having an outer diameter D11 to an axis X1, larger than an inner diameter D1 of the insertion hole 32a. The pressing plate 80 is mounted on the combustion chamber front plate 30 to keep a state that the projection portion 52 is kept into contact with two points of the first inclination portions 33a, 33b.SELECTED DRAWING: Figure 6
