国内1000MW火电汽轮机结构性能优化对比与分析

Contrast and Analysis of Domestic 1000MW Coal-fired Unit Steam Turbine Structure

我国从2004年开始开工建设1 000 MW燃煤火电机组,经过十余年的发展,百万机组以其优异的安全、经济和环保性能逐渐成为电网的主力机组。对我国目前一次再热百万机组所采用的主汽轮机使用情况进行了介绍,针对结构优化进行了对比分析,指出了高参数、大容量汽轮机未来的发展方向。

China started to construct 1000MW coal-fired thermal power plant from 2004, after more than ten years of development, 1000MW unit with its excellent safety, economic and environmental has gradually become the main power unit.The paper introduces the application situation of single reheat 1000MW unit steam turbine used in China at present, contrasts and analyses the structure optimization, points out the future development direction of high parameter and large capacity steam turbine.
