Isolated desuperheater for turbine extraction of large steam turbines is a new technique to improve the thermal economy of the heat cycle.Why it can be improved? How much it improves the turbine heat rate? What is the effectiveness of adopting isolated desuperheater for various extrations? Which is better,Whether the isolated desuperheater in series or in parallel with the feed water heater In resolving these technical problems,qualitative ano analyses are carried out according to the principle of entropy increase.Under the direction of these qualitative analyses,and by means of Mr.F.L.Mas theories of "Functions of Steam Cycles" and "Equations for Optimum Enthalpy Rise",20 schemes are compared for two different classes of 300MW turbine-generator sets,either with or without an extraction from the high pressure turbine.The conclusion recommends that isolated desuperheater in series with high pressure heater for higherly superheated extractions with their enthalpy rise properly increased is effective measure to improve thermal efficiency of large turbine-generator sets as well as to save energy.

独立的抽汽冷却器是大型机组回热系统提高热效益的新技术。这项新技术为什么可以降低汽轮机组热耗?机组热耗可以降低多少?各级抽汽采用独立冷却器的效益如何?独立冷却器与高压加热器是串联还是并联好?对这些技术问题,本文应用熵增原理进行定性分析,并在定性分析的指导下,应用文献[2]提出的“循环函数”和“最佳分配方程”,对高压缸有无一级抽汽的两类30万千瓦机组热力系统,进行了20个方案的计算比较。综合这些分析比较,可以认为,过热度较高的回热抽汽采用串联的独立冷却器,适当加大该级给水焓升,是提高大型机组热效率、节约能源的有效措施。

The said complex systems include: (1 )the superheater arrangement in which the entire superheater system is divided into two paths and the superheated steam leaves at one end of the main header of the two paths, and ( 2 ) those in which the method of lead-in and lead-out of the superheater tube banks does not belong to the typical...

In this article the method of calculation of flow deviation in the complex superheater connection systems frequently used in conventional large capacity utility boilers is given. The said complex systems include: (1 )the superheater arrangement in which the entire superheater system is divided into two paths and the superheated steam leaves at one end of the main header of the two paths, and ( 2 ) those in which the method of lead-in and lead-out of the superheater tube banks does not belong to the typical "Z", "U" or "L" arrangement, but instead several steam leads are arranged for lead-in and lead-out at the middle of the headers. Finally a simplified nornogram for the calculation of flow d2\'iation in typical systems of header arrangement is obtained with the help of a digital computor and presented in the paper.
