题目

The diagram below shows how geothermal energy is used to produce electricity.

Summarise the information by selecting and reporting the main features and make comparisons where relevant. (C12T8)

范文

The working theory of utilising geothermal energy to produce electricity is demonstrated by this flow chart.

Initially, cold water will be pumped into the injection well, which is underground at the depth of around 4.5 kilometres. After being injected, cold water will flow through the geothermal zone, where it will be heated by hot rocks. After becoming hot water, it will be kept in the production well. Thereafter, through pipes, the hot water will be pumped again up to a condenser on the ground.

Then, the hot water in this condenser will emit steam with high temperature. Being powered by the steam the turbine begins spinning. Subsequently, the generator will be driven by the spinning turbine, thus producing electricity. Thereafter, the electricity from the generator will be transported to the grid for all users.

To sum up, the flow chart reveals how geothermal energy is used for generating electricity in five sequential stages. During the whole process, cold water will be heated and release steam which is able to power the generator. This is how the whole process functions

该流程图展示了利用地热能发电的工作原理。

首先，冷水会被泵抽到注入井中，该井位于地下4.5公里处。在被注入之后，冷水将流过地热区，在该区冷水会被高温石加热。在变成热水之后，它将被保存在产生井中。此后，热水经由管道被泵向上抽，注入地表的冷凝器中。

然后，热水在冷凝器中会释放出高温蒸汽。涡轮被这些蒸汽驱动开始旋转。随后，发电机会被这些旋转的涡轮驱动，因此产生电能。此后，来自发电机的电能会被传输到电网上为所有用户所用。

总之，这个流程图通过五个连续的步骤揭示了地热能是如何被利用来发电的。在整个过程中，冷水会被加热，然后释放出可以驱动发电机的蒸汽。这就是整个过程的运行方式。
