应用三维等参元法编制了计算机程序,对锅炉起停过程中汽包应力场及强度进行了计算分析,得到了一些新的理论和观点,可提高自然循环锅炉机组的起停速度及参与调峰的灵活性。
The computer program was developed by using the three-dimensional isoparametric method. The stress field and strength of the steam drum during the start-stop process of the boiler were calculated and analyzed. Some new theories and views were obtained, which can improve the start-stop speed and participation of the natural circulation boiler unit Peak flexibility.
