在 CB25—90/41/13型2.5万千瓦抽汽背压式汽轮的设计过程中,我们曾经对41大气压工业调整抽汽的配汽机构的选择进行过分析论证。当时,国内尚没有设计、制造过抽汽背压式汽轮机,特别是有关高压调整抽汽的配汽机构,更无成熟的经验可供借鉴。因此,我们将国内、外凡是用于抽汽式汽轮机上的配汽结构进行了收集、综合,提出了三种

In the design of the CB25-90 / 41/13 25,000-kilowatt extraction back-pressure steam turbine, we conducted an analysis and demonstration on the selection of the steam-distributing mechanism for industrial steam extraction with a pressure of 41 atmospheres. At that time, there was still no domestic design and manufacture of steam extraction back pressure steam turbines, especially the high-pressure steam extraction and adjustment agencies, more immature experience to learn from. Therefore, we collect and synthesize the steam distribution structure which is used in extraction steam turbine at home and abroad, and put forward three kinds
