参考范文 一

The diagram illustrates the process of producing electricity with geothermal energy in a geothermal power plant.

There are several important steps in energy producing. A huge container should be first prepared for storing up adequate cold water. The water is then pumped from the surface down in a 4.5km deep injection well. Geothermal zone is the next station for the water and here the rocks are hot. After running through geothermal zone to the production well, the water gains a higher temperature. Next, the hot water is ready to be pumped back to the surface into a larger container called condenser. This is done by turning hot water into steam and then directing the steam at a turbine. The steam turns the turbine blades, converting heat into mechanical power. This in turn runs the generator, which produces electricity.

In summary, electricity is produced in the geothermal power plant in several steps: the first step is to heat water, followed by turning it into steam and finally powering the generator to produce energy.

此图说明了地热能发电厂用地热发电的过程。

能源发电有几个重要的步骤。首先，一个巨大的容器用来盛装足够的冷水。然后将这些水从地表打到深4.5千米的注水井。此后，这些水将经过地热区，这里的岩石非常烫。在流过这些炙热的岩石后，这些水将到达生产井，水的温度将上升。接下来，热水等待着被抽回地表，并进入一个更大的容器，称为冷凝器。随后这些热水会在此转化为蒸汽，并被导入涡轮机。这些蒸汽开始使得涡轮机慢慢转动，将热能转化为机械发电。这转而带动了发电机，并提供电力。

总而言之，地热发电厂的电是分几个步驟来产生的：先是将水加热，然后将水变为蒸汽，通过发电机进行发电。

The diagram outlines how electricity is generated from geothermal energy in a geothermal power plant.

The entire electricity-producing process can be divided into several steps. First of all, a huge container on the ground is prepared for cold water. Next, the water is then pumped down an injection well which is as deep as 4.5km.When water reaches the injection well,it runs through hot rocks called a Geothermal zone and is heated up. After the heating process, the hot water is then pumped to the surface into a large condenser up the production well and then turns into steam. Finally, the condenser directs the steam at a turbine, converting heat into mechanical power. This in turn runs the generator, which creates electricity.

In summary, the geothermal power plant is used to generate electricity in three main stages：heating water followed by turning it into steam, and finally powering the generator to produce electricity.

此图叙述了地热能发电厂如何通过地热发电的。

整个发电过程可以分为几个步骤.首先，地表上一个巨大的容器用来盛装冷水。然后， 这些水会被打到4.5米深的地下注水井。当水到达注水井，会通过炙热的岩石，或称地热区，这些水会被加热。在热处理之后，这些热水会被注入地表，进入到生产井上面的一个大型冷凝器中，然后变成蒸汽。最后，冷凝器会将蒸汽送到涡轮机，将热能转化为机械发电。这转而带动发电机发电。

总而言之，地热能发电厂被用于发电主要为三个阶段。阶段是加热水，然后将其转化为蒸汽，最后带动发电机来发电。
