引言Steag 所进行的富有启发性的研究工作是基于锅炉容量增长率为8.5%/年,这一增长率是根据所希望的电力需要增长率为7.2%/年和电站按25年运行寿命推算出来的。若以这样的增长模式继续发展下去,则每隔10年锅炉机组的容量将随装机容量的翻一番而同样地增加一倍。实际上西德近20年烧化石燃料的锅炉机组也证实了这种发展。若这样的发展趋势持续下去,到1984年将有120万千瓦、1994年相应地将有240万千瓦的大容量锅炉投入运行。如图1所 INTRODUCTION Steag’s instructive research work is based on a boiler capacity growth rate of 8.5% / year, based on the expected 7.2% / year increase in electricity demand and 25-year operating life of the plant of. If this growth pattern continues to develop, the boiler capacity will double equally every 10 years as the installed capacity doubled. In fact, the fossil fuel fired boiler unit in West Germany nearly confirmed this development. If such a trend continues, there will be 1.2 million kilowatts by 1984 and 2.4 million kilowatts of high-capacity boilers will be put into operation in 1994 accordingly. As shown in Figure 1
