前言火力发电设备作为中间负荷机组的任务正在逐年增加。最近,35万千瓦等级的火力发电机组在深夜停机,50万千瓦以上的大容量火力发电机组在夜间处于低负荷运行(30%负荷左右),有一部分已投入实际运行了。随着原子能发电比率的增加,可以预计今后承担中间负荷的火电机组将趋向大容量化,也就是50～100万千瓦的大容量火力发电机组必须具备能在深夜停机或能在25%负荷以下运行的性能。由于1973年石油冲击而造成的能源价格的上涨,对发电效率的
Foreword The task of thermal power generation equipment as an intermediate load unit is increasing year by year. Recently, the 350,000-kilowatt thermal power plant was shut down late at night, and the large-capacity thermal power units above 500,000 kilowatts were in low-load operation (around 30% load) at night, and some of them were actually put into operation. With the increase of nuclear power generation rate, it can be expected that in the future, the thermal power generating units undertaking intermediate loads will tend to be larger in capacity, that is, the large-capacity thermal power generating units of 50 to 1 million kilowatts must be capable of shutting down late at night or operating below 25% load Performance. The rise in energy prices due to the impact of the oil in 1973 on the efficiency of power generation
