引言现代蒸汽发生设备设计的准则很多,千变万化,且常相互有联系,但大致能妥善地归纳为:价格、运行效率和设备的可用率。它们的相对重要性要视某一时期内的经济形势而定。两年前在这个会议上(指美国动力会议——译注),Morong 和Patterson 提出了一篇精采的论文,文中他们给出了提高可用率的如下设计原则:1.选购优质设备;2.慎重精确配合机组各系统; INTRODUCTION There are many, ever changing, and often interconnected, guidelines for the design of modern steam generating equipment, but they are broadly categorized as price, operational efficiency, and equipment availability. Their relative importance depends on the economic situation in a given period. Two years ago at this conference (referring to the US Dynamics Conference), Morong and Patterson presented a brilliant essay in which they presented the following design principles for increasing availability: 1. Purchase of premium equipment; Carefully and accurately with the crew of the system;
