循环水进水温度与汽轮机真空度的简单分析(国外英文资料) Simple analysis of water inlet temperature and steam turbine vacuum The relationship between the water inlet temperature and the vacuum of the steam turbine The vacuum of the steam turbine is a key parameter that has been affecting the safety and economic operation of the unit. Circulating water inlet temperature, which is a main factor of the steam turbine vacuum, vacuum and steam turbine, affect the water condenser circulating water temperature, and then affect the circulating water inlet water temperature, both closely related and influence each other. The main factors influencing the two are: (1) cooling tower water cooling effect The temperature, the wind speed, the output of the fan, the water and the water, the water temperature, etc. (2) the condensers circulate water Secondary filter including circulating water pump sets, circulating water clean degree, the import and export of various electric door opening condenser circulating water and circulating water system leaking and other cooling water system, such as the size of the concrete embodiment in the import and export of condenser circulating water pressure. (3) the heat transfer capacity of the condenser Including the condenser in the clean degree of heat exchange surface (copper), vacuum system leakage air volume, quantity, steam turbine into paragraphs extraction amount (the size of the heating load is the main change in) the quality of circulating water, and put into effect of rubber ball cleaning system, concrete embodiment in the condenser vacuum, exhaust temperature, and the condenser circulating water temperature and the load parameters such as import and export. Data collection: Considering the change of the operating point of # 1 machine, the change of the load is relatively fast, and the load change is large, so the statistics and analysis of the production report data are made on April 15, April 15. 2 a day, a circulating water temperature low at 5:00 ~ 8:00, high
