一、基本概念汽轮发电厂的生产設备和循环理論的发展,是以簡单的凝汽循环(朗肯循环)为基础的;簡单凝汽机組与簡单背压机組組合成热化机組和具有給水回热加热的机組,可以把它們的进汽分成两种汽流:凝汽汽流(К汽流),和背压汽流(П汽流),П汽流的特点是作功热耗率等于1。复合循环的概念[Л.2]要会灵活运用,例如:对于蒸汽的再过热系統可以有两种复合方式,根据工作目的分別应用。
First, the basic concepts Turbine power plant production equipment and the development of the theory of circulation is based on a simple condensate cycle (Rankine cycle) as a basis; a simple condensing unit with a simple back-pressure unit into a combination of heat Turbocharged units and units with regenerative heating of the feedwater can separate their intake into two steam streams: steam condensate (К steam), and backpressure steam (П steam), П steam The characteristic is that the heat consumption rate is equal to 1. The concept of a compound cycle [Л.2] should be used flexibly. For example, there are two types of recombination systems for steam reheating, which are applied depending on the purpose of the work.
