| Abstract: | An experimental investigation on thermal stresses of a type TK-120 reheat unit at Huainan power station during transient process are developed. The reasons for station deformation of the intermediate pressure cylinder and the stress level during transient process are also analyzed. The results of the experemental investigation are available to lay down the optimas type of start-up and shut-down procedure. |
