Author has discussed the Corrosive form and the rust fouling pattern for the low pressure cylinder of CO2 compressor;analyzed the corrosive mechanism for oxygen corrosion,CO2 corrosion and their effecting factors;anti-corrosion measures were supposed from aspects of operation,maintenance,repair and process design etc.

The construction and function of protection circuit and interlock circuit for the thermal engineering after the through-flow capacity of low pressure cylinder of 200 MW unit made in China was introduced , and the interlock relationship among the loops was also discussed, the application effectiveness of its protection and interlock system was presented as well.

It discusses the location and characteristics and causes for turbine low pressure cylinder,and suggests some measures of preventing & slowdown this corrasion.

This paper analyzes the reason of distortion of low pressure casing, and discusses the effects of distortion of low pressure casing on operation stability of low pressure bearing.

In order to meet the needs for performance analysis of thermal power units, it is discussed in this thesis that the calculating models of low pressure casing efficiency of steam turbine is predigested.

The Boring Equipment Research on Mitsubishi LP Cylinder Bearing Spherical Surface;

and four processing methods for condition curves in calculation of specific enthalpy for exhaustc steam from LP cylinder at home and abroad being presented,and the advantages and disadvantages of each method being analysed.

With the analysis of the unit structure and various influencing factors which may cause the vibration, it draws a conclusion that the high exhaust steam temperature of LP cylinder is the immediate cause of the vibration in start up period, while the great circulating water inlet pressure of the condenser is the reason for the vibration during operation.
