火力发电厂是燃烧燃料来发出电能的工厂。所用燃料有煤、油、木柴、气体燃料等。火电厂的生产过程,实质上是能量转变的过程。使用蒸汽的发电厂,有三个主要部分:锅炉、汽轮机和凝汽器、发电机。在锅炉内燃烧燃料,把燃料的化学能释放出来,使锅炉的水变成蒸汽。蒸汽带着热能,经过主蒸汽管通到汔轮机,在机内经过若干喷嘴和好几道汽叶,使蒸汽 Thermal power plants are plants that burn fuel to generate electricity. The fuel used is coal, oil, firewood, gas fuel and so on. The production process of thermal power plants is essentially the process of energy transformation. Power plants that use steam have three main parts: boilers, steam turbines and condensers, generators. The fuel is burned in the boiler to release the chemical energy of the fuel and turn the water in the boiler into steam. Steam with heat, through the main steam pipe to the turbine, in the machine through a number of nozzles and several steam leaves, the steam
