Nozzle for supercritical water, method for producing clean water using the nozzle for supercritical water, and supercritical water reactor

摘要

PROBLEM TO BE SOLVED: To miniaturize a supercritical water reaction apparatus by small-sizing an external diameter of a nozzle for supercritical water. SOLUTION: The nozzle 10 for the supercritical water, which is constituted by having an outer pipe 14 and an inner pipe 11 inserted into the inner space of this outer pipe 14 and disposing spacers (for example, projecting parts 11a and 14a and a ring 19) for locating the outer peripheral surface of the inner pipe in a prescribed position with respect to the inner peripheral surface of the outer pipe 14 near a nozzle spout 16 into a reactor 1, is provided. The supercritical water reaction apparatus is provided by using such nozzle 10 and combining the same with the reactor 1, etc.
