| Abstract: | Expansion - difference is the important factor of the turbine start - up speed and safe operation for unit. The research of the expansion - difference in varying operating conditions of unit has practical significance. The article introduced the reason of differential expansion and computational formula, through the analysis of the factors in operation, equipment structure and parametric variation of 300MW turbine, offered the methods of reducing the differential expansion and differential expansion control key points in variable operating conditions of turbine. |
