The present invention provides an underground storage method for carbon dioxide that ensures the strength of a carbon dioxide–blocking layer and makes it possible to reliably seal carbon dioxide at an appropriate depth range in the layers of the ground and efficiently store a large amount of carbon dioxide. The present invention provides an underground storage method for carbon dioxide that involves forming a carbon dioxide storage layer (G) by pressing carbon dioxide below a carbon dioxide–sealing region S that is a layer of ground that exists to a prescribed depth from the surface F of the seabed and satisfies pressure and temperature conditions that make it possible to generate carbon dioxide hydrate, forming a carbon dioxide–blocking layer (C) in the carbon dioxide–sealing region (S) by allowing at least a portion of the carbon dioxide pressed into the carbon dioxide storage layer (G) to naturally rise to the carbon dioxide–sealing region (S) side by the buoyancy of the carbon dioxide and thereby generating carbon dioxide hydrate, and storing the carbon dioxide at a depth range in the layers of ground below the surface (F) of the seabed that satisfies pressure and temperature conditions that balance the density of the carbon dioxide and the density of pore water.

Abstract
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.
