火力发电机组汽水管路的热应力及其补偿方式

Analysis on Thermal Stress and Compensation Method of Steam Water Pipeline of Thermal Power Unit

我国电力工业发展中确保既安全又可靠的电力生产供给尤显关键,而大型火电机组中的汽水管路常因较大的温差引起管路变形甚至断裂,严重时还会影响机组其他动力设备的安全运行。所以,试析原因并找到管路补偿措施,以保证机组的安全运行。

In the development of China’s power industry,it is particularly important to ensure a safe and reliable supply of power production,and the steam and water pipes in large thermal power units are often distorted or even broken due to large temperature differences,serious will also affect the safe operation of other power equipment,so this paper try to find the cause of pipeline compensation measures to ensure the safe operation of the unit.
