STEAM ELECTRICITY GENERATION EQUIPMENT UTILIZING HEAT OF MAGMA OR MAGMA DEPOSIT IN EXTINCT OR ACTIVE VOLCANO OR UNDERGROUND WATER PERMEATION LAYER

摘要

PURPOSE:To directly utilize the heat of magma and heighten thermal efficiency, by providing a heat exchange steel pipe directly in a magma deposit to generate electricity by steam. CONSTITUTION:A heat exchange steel pipe 2 is provided with a heat insulation double construction. The inner thin tube of the pipe 2 is a steel tube 9 to supply water from a water feeder B to a heat exchange section 7. Steam 10 generated in the heat exchange section 7 by the heat 8 of magma is conducted to the turbine of an electricity generator A through a special steel pipe 4 which is the outer thick tube of the heat exchange steel pipe 2.
