Preface to Operators Guide to General Purpose Steam Turbines PDF


“We are what we repeatedly do. Excellence, then, is not an act, but a habit.” 

If you operate steam turbines in your plant you are probably asking: Why do I need a whole book devoted to steam turbine operations?


Th e short answer is because we all want our steam turbines to operate reliably and safely during their lifetimes and to avoid nasty surprises, such as massive failures, unexpected outages or injuries.

Owners of steam turbines should continuously strive to protect life, limb and property and minimize the life cycle costs through the use of proven operating practices like those contained in this Operators Guide to General Purpose Steam Turbines book.

The best practices presented in this Operators Guide to General Purpose Steam Turbines book can be used as a basis for your plant’s steam turbine reliability program and operating procedures.

Th e life cycle cost (LCC) of a machine is the total of the purchase, installation, repair, and operating costs incurred throughout its lifetime.

As an operator the only way to affect a steam turbine LCC is by minimizing maintenance cost. Th is is accomplished by employing proven start-up procedures that will minimize undue stresses and erosion and by monitoring them in order to detect minor issues before they lead to costly repairs.

General purpose (GP) steam turbine drivers present operators with special challenges because they tend to have a minimum of automation and instrumentation which makes their reliability dependent on the skill and knowledge of their caretakers.

In other words, their reliability is dependent on the quality of human implemented procedures and human-based monitoring methods.

When installed and operated properly, GP steam turbines are reliable and tend to be forgotten, “out of sight, out of mind”.

But these sleeping giants can create major headaches if ignored. Three real steam turbine undesirable consequences that immediately come to mind are:

• Injury and secondary damage due to an overs peed failure. An over speed failure on a large steam or gas turbine is one of the most frightening of industrial accidents.

A huge amount of thermal, chemical, and mechanical energy  is contained within a large steam turbine when it is in service.

If the rotational  speed  of the steam turbine ever exceeds its safe operating limits, the main shaft and impeller wheels can be pulled apart by centrifugal force, releasing a tremendous amount of energy.

In the worst case, the disintegrating parts can break through the turbine housing and fling hot, fast-moving shards of metal in all directions.

The results of such a failure are always very costly due to the peripheral equipment damage and can sometimes be fatal to personnel in the area. 

• Th e high cost of an extensive overhaul due to an undetected component failure. Th e cost of a major steam turbine repair can run ten or more times that of a garden variety centrifugal pump repair.

If an early failure is not detected, it will usually result in a more costly failure. For example, a simple packing leak can result in oil contamination, which can lead to a bearing failure, which can lead to major rotor damage.

Repair cost can rapidly escalate if the chain of failure events is not stopped early, i.e., in the primary stage. Costly production losses due an extended outage if the driven pump or compressor train is unspared.

Th e value of lost production can quickly exceed repair costs. Extending the mean time between repairs though the implementation of best practices will in turn reduce production downtime and dramatically increase overall profits.

A major goal of this Operators Guide to General Purpose Steam Turbines 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 scenarios, such as:

1. Overs peed trip testing. 

2. Starting up a proven steam turbine driver after an outage. 

3. Shutting down a steam turbine driving a centrifugal pump or centrifugal compressor.

4. Commissioning a newly installed steam turbine 5. Starting up after a major steam turbine repair.

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.

Operators must be fully committed to following the prescribed steam turbine operating procedure every time and carefully monitoring them in the field in order to detect signs of early failures before serious damage is done.

To support this commitment this Operators Guide to General Purpose Steam Turbines book will:

• Provide operators with a broad exposure to the principles of steam turbine design and operations 

• Explain common failure modes and how they can be prevented or mitigated and 

• Provide proven operating procedures that can protect your steam turbines from costly and dangerous failures.
