蒸汽动力系统可调节性分析

An Analysis of the Regulation Possibility of Steam Power Systems

:工厂中经常出现的变动情况决定蒸汽动力系统须具有一定的可调节性。本文以总复合曲线为工具 ,分析比较了采用背压式汽轮机组和采用抽汽凝汽式汽轮机组的蒸汽动力系统 。

A constant change of situations in a factory demands that a steam power system s hould lend itself to be readily regulated within certain limits. With general c omposite curves serving as a tool this paper makes an analytical comparison of t he steam power systems using respectively a back pressure steam turbine unit an d an extraction condensing steam turbine unit. Furthermore, a specific example is used to explain how to design a steam power system featuring a good regulation possibility with the help of the general composite curves.
