大功率汽轮机的经济设计点及经济运行特性分析

An Analysis on the Optimized Design Point of High-Power Steam Turbine and Its Economic Operation

本文基于宏观通流热力设计的通流面积与通流能力匹配设计,说明大功率汽轮机经济设计点的确定和与设计点相对应的经济运行方式.为电站汽轮机设计条件的正确确定和机组长期经济运行模式提供参考.对全国范围内实现大容量火电机组的节能减排提出-种新思路.

Based on the matching design of the flow area and the flow capacity of macroscopic through-flow thermodynamicdesign, this paper illustrates the certainty of the optimized design point of high power steam turbine andcorrespondent mode of economic operation, provides reference for the correct determination to the design conditionsof power station steam turbine and for long-term economically operational mode of generator sets, and puts forwarda new kind of thought to realize in the whole country energy conservation and emission reduction of .high-capacitythermal power units.
