电力是工厂中主要的原动力,我们日常生活中也很需要它。因为电力比其他各种原动力更便于传送,又很便于转化成其他形态的能,很容易变成热能、光能、机械能,化学能,所以应用非常广泛。很多人都想知道电力是怎样产生的,这里准备带同志们去电力的发源地——火力发电厂去参观。走进一座火力发电厂(图1),先看看燃料储存的场所和燃料运输的设备。火力发电厂的燃料有煤、木柴、砻糠和重油等固体和液体燃料,但一般都用煤。储存煤的场所叫储煤场。储煤场绝大多数是露天的,也有为了
Electricity is the main driving force in the factory. We also need it in our daily lives. Because electricity is easier to transmit than other kinds of motive power, and it is easy to be converted into other forms of energy, it is easy to turn into heat energy, light energy, mechanical energy, and chemical energy, so it is widely used. Many people want to know how electricity is generated. Here, we are preparing to bring comrades to visit the power plant, which is the birthplace of electricity. Into a thermal power plant (Figure 1), take a look at the location of fuel storage and fuel transportation equipment. Coal-fired power plants have solid and liquid fuels such as coal, firewood, plutonium, and heavy oil, but coal is commonly used. The place where coal is stored is called the coal storage yard. The vast majority of coal storage sites are open-air and there are also
