现代火力发电厂,汽轮机组正朝着大容量、高参数方向发展。而那些在五、六十年代曾起过重要作用的中低压机组,发电煤耗比大容量机组要高30～50％(约多150～160克/千瓦小时),很不符合我国当前的能源政策,势必为大容量、高参数的机组所取代。但迄今,我国仍有一千多万千瓦的中、低压汽轮发电机组在运行。如何在目前条 Modern thermal power plants, steam turbines are moving towards large-capacity, high-parameter direction. However, medium- and low-voltage units that played an important role in the 1950s and 1960s generated 30-50% higher coal-fired power (about 150-160 g / kWh) than high-capacity units, which is not in line with China’s current energy policy , Is bound to replace high-capacity, high-parameter unit. But so far, there are still more than 10 million kilowatts of medium and low pressure turbine units in operation in our country. How in the current article
