題目

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

該流程圖展示了利用地?zé)崮馨l(fā)電的工作原理。

首先，冷水會被泵抽到注入井中，該井位于地下4.5公里處。在被注入之后，冷水將流過地?zé)釁^(qū)，在該區(qū)冷水會被高溫石加熱。在變成熱水之后，它將被保存在產(chǎn)生井中。此后，熱水經(jīng)由管道被泵向上抽，注入地表的冷凝器中。

然后，熱水在冷凝器中會釋放出高溫蒸汽。渦輪被這些蒸汽驅(qū)動開始旋轉(zhuǎn)。隨后，發(fā)電機(jī)會被這些旋轉(zhuǎn)的渦輪驅(qū)動，因此產(chǎn)生電能。此后，來自發(fā)電機(jī)的電能會被傳輸?shù)诫娋W(wǎng)上為所有用戶所用。

總之，這個流程圖通過五個連續(xù)的步驟揭示了地?zé)崮苁侨绾伪焕脕戆l(fā)電的。在整個過程中，冷水會被加熱，然后釋放出可以驅(qū)動發(fā)電機(jī)的蒸汽。這就是整個過程的運行方式。
