Steam turbine lubrication has passed through three phases. The first was typified by oils not sufficiently refined for good stability and operating in bearings with insufficient cooling and excessive moisture infiltration from shaft seals. The second phase was initiated by an effort to produce a much more highly refined oil, and this had some unfortunate results in operation due to early breakdown of new oils in the presence of rust from the oil piping, which in turn was the indirect result of over-refining. In the third phase this was remedied by the introduction of inhibitors; turbine lubrication today has very long service life expectancy. However, the ultimate life of a high-grade inhibited oil is not definitely known because insufficient time has elapsed since the advent of inhibitors, and the ultimate breakdown of some inhibited turbine oils may occur rather suddenly. Reliable laboratory tests are badly needed for predicting the probable service life of a new oil and for evaluating old oils in operating service, so that their condition can be accurately determined before a breakdown actually occurs. Some standard tests for turbine oils are discussed in terms of their value to the operator, and their limitations are pointed out by actual case histories. Some modifications of existing standard stability tests are proposed and these are supported by laboratory test data. The need for further research along specific lines is suggested, and also discussed is the problem of establishing safe limits for the quality of an oil in service before it must be replaced.

When installed and operated properly, general purpose steam turbines are reliable and tend to be forgotten, i.e., out of sound and out of mind. But, they can be sleeping giants that can result in major headaches if ignored. Three real steam turbine undesirable consequences that immediately come to mind are: Injury and secondary damage due to an overspeed failure. An overspeed failure on a big steam or gas turbine is one of the most frightening of industrial accidents. The high cost of an extensive overhaul due to an undetected component failure. A major steam turbine repair can cost ten or more times that of a garden variety centrifugal pump repair. Costly production loses due an extended outage if the driven pump or compressor train is unspared. The value of lost production can quickly exceed repair costs. A major goal of this book is to provide readers with detailed operating procedure aimed at reducing these risks to minimal levels. Start-ups are complicated by the fact that operators must deal with numerous start-up scenarios, such as: Commissioning a newly installed steam turbine Starting ups after a major steam turbine repair Starting up a proven steam turbine after an outage Overspeed trip testing It is not enough to simply have a set of procedures in the control room for reference. To be effective, operating procedures must be clearly written down, taught, and practiced—until they become habit.

When it was first published some two decades ago, the original Handbook of Lubrication and Tribology stood on technology's cutting-edge as the first comprehensive reference to assist the emerging science of tribology lubrication. Later, followed by Volume II, Theory and Design and Volume III, Monitoring, Materials, Synthetic Lubricants, and Ap

Contains eight papers from a June 2000 symposium held in Seattle, Washington, reporting on research related to the lubrication requirements of turbines used for power generation. Papers reflect two general trends in the field: the production of more stable lubricants, and the development of improved
