JPS5638577A - Method and plan for power generation by direct utilization of volcano - Google Patents

Abstract

PURPOSE: To prevent the damage of an indirect heat-collecting pipe due to melting and the occurrence of environmental pollution by a method wherein the circulating water in the indirect heat-collecting pipe is heated by the intense heat of a volcano and the high-temprature water thus heated is utilized for the generation of electric power.

CONSTITUTION: An indirect heat-collecting pipe 1 is constituted by an outer pipe 21, an inner pipe 23 supported therein concentrically through the intermediary of a spacer 22, a cover 24 for the end part of the outer pipe and an end plate 25 of the inner pipe. In the peripheral wall of the end part of the inner pipe 23 and in the end plate 25 of the inner pipe are provided many watering orifices 26, and the water sent by a pump flows toward the tip of the outer pipe through a flowing channel between the outer pipe 21 and the inner pipe 23. Then, being heated by the steam of high temperature in a lava pond, it turns to be a steam of high temperature or a mixed fluid of this and the water of high temprature, and the fluid of high temperature thus produced is sent to the power-generating equipment through the inside of the inner pipe 23, where, by the heat of the fluid of high temperature, the generation of electric power is performed.
