1.\x05Topic:火电厂thermal power plant
2.\x05Purpose:火电厂是电能生产的重要组成部分.在全世界范围,火电厂的装机容量占总装机容量的70%,发电量占总发电量的80%.由此可见,火电厂无论是对国民经济 的发展,还是人民生活水平的提高,都起着重大作用.
3.\x05(1)What is thermal power plant
它是利用煤、石油、天然气等固体、液体燃料燃烧所产生的热 能转换为动能以生产电能的工厂.
(2)history
1875年法国巴黎北火车站建成世界上第一座火电厂并开始发电,采用很小的直流电机专供附近照明用电,随后美国、俄国、英国也相继建成小火电厂.
1886年,美国建成第一座交流发电厂.
(3)现代化的火电厂是一个庞大而又复杂的生产电能与热能的工厂.
它由下列5个系统组成:
①燃料系统:完成燃料输送、储存、制备的系统.
②燃烧系统:完成燃料燃烧过程,使燃料化学能转化为蒸汽热能的系统.
③汽水系统:完成蒸汽热能转化为机械能的系统.
④ 电气系统:完成机械能转化为电能及电力输送的系统.
⑤ 控制系统:完成生产过程中的参数测量及自动化监控操作的系统.
1. The Topic: the power plant thermal power plant
2. Purpose: the power plant is an important part of electrical energy production. In the world scope, construction of coal-fired power plants with a total installed capacity of an installed capacity of accounting for 70% and of the total capacity of the capacity by 80%. This shows, the power plant both for the development of national economy, or the improvement of people's living standard, plays a major role.
3. (1) What is thermal power plant
It is the use of coal, oil, natural gas and solid, liquid fuel from the burning hot will translate into kinetic energy of the electrical power produced by the factory.
(2) history
In 1875, Paris, France, north railway station built the world's first a coal-fired power plant and began to power generation, using small dc motor near for illumination, then the United States, Russia, Britain also have built small thermal power plant.
In 1886, the United States built the first a communication power plants.
(3) of the modernization of the power plant is a vast and complex production electric energy and heat energy plant.
It consists of the following five system composition:
(1) the fuel system: complete fuel transportation, storage, preparation of the system.
(2) the combustion system: complete fuel combustion process, to make the fuel chemical energy into steam heat energy system.
(3) soda system: complete steam heat energy into mechanical energy system.
(4) the electrical system: complete mechanical energy into electrical energy and power transmission system.
(5) control system: complete production process parameters measurement and automation of operation monitoring system.
