Claims

[Claims for Utility Model Registration] (1) A burner having a generally circular tip surface includes a combustion gas passage, an auxiliary combustion gas passage, a number of mixed gas passages connected to both of the passages, and a powder passage. A mixed gas passage and a powder passage are opened at the tip surface of the burner, a powder port and a flame port are formed at the open ends of these passages, and the mixed gas in the mixed gas passage is passed through the flame. The flame ports are opened in one or more rows each in the annular part near the center and the annular part near the outer periphery of the tip surface, and the powder ports are opened in the circumferential direction between the two annular parts. a main powder passage that is opened at multiple locations spaced apart from each other and extends through the center of the burner into the powder passage;
A plurality of branch powder passages are provided which branch from the main powder passage and whose tips form the powder ports, and a plurality of combustion gas passages are provided in a portion farther from the burner tip surface than the branch powder passages. A pressure equalization chamber extending along the inlet group of the mixed gas passage is formed downstream of the auxiliary gas passage, and the combustion gas pressure equalization chamber and the mixed gas passage are connected by a combustion gas nozzle passage to equalize the pressure of the auxiliary gas. A thermal spray burner characterized in that a chamber and a mixed gas passage are connected through an auxiliary gas nozzle passage. (2) The thermal spray burner according to claim 1, which is a registered utility model, characterized in that an annular cooling water passage is provided on the outer circumferential side of the outer circumferential side mixed gas passage in a portion near the front end surface of the burner.
