Abstract

Abstract: The variation of turbine blade tip seal clearance will influence on the tip steam leakage and reduce the unit economical efficiency. Based on structure data of a 200MW reheating condensing steam turbine of Inner Mongolia Huadian Zhuozi Power Generation Corporation Limited, by calculation of characteristics of thermodynamic process, the influence of the amount of steam leakage on unit thermal economical performance was determined, which can be used as basis for unit reformation decision.

Key words: blade tip seal, economical efficiency, energy conservation, evaluation
