电厂实习(国外英文资料) I. The purpose and significance of internship The task of this internship is to be familiar with heat energy and power engineering related enterprises, mainly the main thermal system and arrangement of thermal power plants. This visit is the place of power plant model room, Nanjing Xiexin sludge power plant, Nanjing steam turbine factory. Purpose to let students during the internship in brief understanding, and of the thermal power plant the main production equipment and the basic structure, working principle and the performance of such a system, comprehensive understanding, not the follow-up professional courses to provide the necessary basic knowledge and perceptual knowledge. Thermal power plant is a factory that uses the chemical energy of coal, petroleum, natural gas and other fuels to produce electric energy. That is the chemical energy of fuel. The thermal potential energy of steam. In a boiler, the chemical energy of the fuel is converted into heat energy of the steam. In the turbine, the heat energy of the steam is converted to mechanical energy that rotates in the wheel, and mechanical energy is converted into electricity in the generator. Furnace, machine and electricity are the main equipments in the thermal power plant, also known as the three main engine. Auxiliary three host equipment called auxiliary equipment, referred to as auxiliary. The main engine is connected with the auxiliary machine and its connected pipes, lines and so on. The raw material of Xu Tong thermal power plant is raw coal. The car or ship to coal power plant coal storage yard (Nanjing power plant with coal sludge GCL to ship power plant, transportation and transportation belt terminal) to scuttle. From the coal scuttle fell by coal into the coal mill into a coal, and at the same time conveying hot air drying and conveying of pulverized coal. Finally, the furnace is sent into the boiler to burn. Heating air preheater hot air fuel burning need from the blower into the b
