PROBLEM TO BE SOLVED: To provide a burning heater for securing sufficient burning using an air damper for adjusting amount of air for burning in response to the installation height of a heater body. SOLUTION: In this molten slag cooling device for a gasification melting system, air supply route of the air for burning is provided with the closed-end cylindrical air damper 8 having an air passing hole 8a for passing the air for burning, the air passing hole 8a of the air damper 8 is disposed at a position eccentric from the outer diameter center of the air damper 8, and a closed-end cylindrical air orifice 12 having an air passing hole 12a for changing a passing amount of air for burning is engaged with and mounted to the outer periphery of the air damper 8. The molten slag cooling device has the air passing hole 12a of the air orifice 12 at the position eccentric from the outer diameter center of the air orifice 12, and the air orifice 12 is manually rotated circumferentially on the cylindrical outer periphery of the air damper 8, thereby adjusting the passing amount of air for burning based on the rotation position displacement between the air passing hole 8a of the air damper 8 and the air passing hole 12a of the air orifice 12.
