一、简介地热能蕴藏于地球内部,世界许多地方正在进行开发。 1.地球内部的地热能来自: ①从地球内部通过地壳产生的热传导和热对流。②地壳板块碰撞释放出的热。③地壳物质如花岗岩、玄武岩和橄榄岩中放射性元素的衰变。2.目前地热能可经济地进行开发的地质区域发生在:①地壳板块边界地带。②磁性侵入或释放地区,如火山。3.地热热储被划分为以下几类:①热水一蒸气气控型,如美国盖瑟斯、日本和意大利的拉达力罗。②热
I. INTRODUCTION Geothermal energy is contained within the Earth and is being developed in many parts of the world. 1. The geothermal energy inside the Earth comes from: (1) heat conduction and convection from the Earth’s interior through the earth’s crust. ② crust plate collision release of heat. ③ crustal substances such as granite, basalt and peridotite radioactive decay. 2. Currently geothermal energy can be economically developed in the geological area occurred in: ① crust plate boundary zone. ② magnetic invasion or release areas, such as volcanoes. 3. Geothermal heat storage is divided into the following categories: ① a vapor-controlled hot water, such as the United States Gaisi Si, Japan and Italy’s Radariluo Luo. ② heat
