Abstract: Since the thermal power generating enterprises are characterized as “technology intensive” industries considering the prominent contradictions in the current development of the enterprises, this paper expounds the existing problems in the steam turbine units and proposes the direction of improving the overall performance as well as the technical ideas, routes, methods and plans to implement comprehensive retrofits on the basis of corresponding theories. Taking the actual application for example, the paper also presents the way to use logic analysis to determine the cause of the problems, put forward feasible reformation measures and solutions, and put into the implementation to reach significant achievements.

Key words: thermal power generation, steam turbine unit, performance improvement, comprehensive retrofit, technology and application
