SLAG MELTING BURNER APPARATUS

WIPO Patent Application WO/2010/041635

A1

By covering the inner circumferential surface of an outer cylinder with a vapor film, thermal conductivity is reduced and the phenomenon of sudden temperature increases in the cylinder wall of the outer cylinder can be prevented, thereby preventing heat damage to the outer cylinder. Additionally, burner burnout, caused by insufficient cooling resulting from irregularities in cooling efficiency at the burner tip, is also prevented. A tip, which is positioned inside a two-stage entrained-flow bed coal gasification furnace, has a double-walled cylindrical structure with an outer cylinder and an inner cylinder, and is configured so that cooling water to cool the tip is supplied via the inside of the inner cylinder and, after cooling the tip, is returned to the base end via the space formed between the outer cylinder and the inner cylinder, and is additionally configured so that the flow path surface area of the space formed between the outer cylinder and the inner cylinder is less than the flow path surface area formed inside the inner cylinder, thus configured so that a swirling flow along guides formed on the outer circumferential surface of the inner cylinder, and a roughly linear flow in the lengthwise direction of the outer cylinder and the inner cylinder, are imparted to the cooling water that is returning to the base end via the space formed between the outer cylinder and the inner cylinder.
