Zusammenfassung:PROBLEM TO BE SOLVED: To provide a burner which prevents the burner from being thermally damaged and achieves stable gasification operation by suppressing thermal elongation and deformation of a cooling water pipe.SOLUTION: In the burner, which includes: a cylindrical fuel nozzle 5 for jetting pulverized coal 3 conveyed by carrier gas and a cylindrical oxidant supply pipe 7 disposed coaxially with the cylindrical fuel nozzle 5, a groove 13 for mounting a cooling water pipe 9 rolling along an outer peripheral wall is formed on the other outer peripheral wall enclosing either of the cylindrical fuel nozzle 5 or cylindrical oxidant supply pipe 7.
