steam turbine unit REVERSE ENGINEERING PROCESS GE''s reverse engineering process ensures a fast and safe spare parts supply for a large number of industrial steam turbines. The integration of the reverse engineering parts process into the steam turbine outage planning and execution ensures that parts can be supplied during ongoing overhauls.
Reliability: Steam turbine life is extremely long. There are steam turbines that have been in service for over 50 years. Overhaul intervals are measured in years. When properly operated and maintained (including proper control of boiler water chemistry), steam turbines are extremely reliable. They require

The resultant movement of the trip pin causes knifeedges in the linkage to separate and permit the spring loaded trip valve to close. Over speed governors is arranged to trip at 10 percent over normal speed actuating a quick closing stop valve to shut off the steam supply to the turbine.
GE has developed and applied advanced steam turbine technology since 1901, and has deployed more than 530 GW of steam turbine capacity in more than 6,000 installed units since then. With tremendous appliions flexibility, our steam turbines operate in combined .
· Turbine is an engine that converts energy of fluid into mechanical energy The steam turbine is steam driven rotary engine. 7. The steam energy is converted mechanical work by expansion through the turbine. Expansion takes place through a series of fixed blades (nozzles) and moving blades. In each row fixed blade and moving blade are called stage.
An Introduction to Steam Turbine Selection When the end user needs to select a general purpose back pressure steam turbine driver, an exchange of information on required turbine performance will Operator''s Guide to General Purpose Steam Turbines: An Overview of Operating Principles, Construction, Best Practices, and Troubleshooting.
Steam Turbine Operating Conditions The Steam cycle The essential elements of the steam cycle include the boiler (or steam generator), turbines, generator and condenser. A simplified steam cycle7, in this case with a drumtype boiler, is shown schematically in Figure 1. Figure 1. Simplified steam cycle in the power plant7.
Practical Steam Turbine Performance Calculations (using Flex Live''s Steam Flex routine or by manual methods) A steam turbine''s power and/or efficiency can be quickly and accurately calculated using Flexware''s Steam Flex steam properties program. It will be necessary to obtain the following operating data from the field.

The nozzle converges first to the smallest section and then diverges up to exit. The smallest section of the nozzle is called throat.
Steam turbine blading can be subjected to several failure mechanisms in service. These mechanisms are indied in Table 1 along with the resultant damage and typical causes of failure. For steam turbines to operate with high reliability and availability, the ability to

Steam turbines are well suited as prime movers for driving boiler feedwater pumps, forced or induceddraft fans, blowers, air compressors, and other rotating equipment. This service generally calls for a backpressure noncondensing steam turbine. The lowpressure steam turbine exhaust is available for feedwater heating, preheating of

to steam turbine or diesel engine installation. In terms of fuel economy, modern marine GTEs can compete with diesel engines and they may even be superior to boiler/steam turbine plants that are operating on distillate fuel. The GTEs do have a few disadvantages. Since they are highperformance engines, many parts are under high stress.
Figure 1: Steam Turbine Cycle High pressure steam flows into the turbine and past its blades. In doing so, the blade shaft begins to spin. The blade shaft is directly connected to an electrical generator where it starts producing electrical power. The power output from the cycle is relative to the drop in steam pressure through the turbine.

steam is expanded to a lower pressure in the turbine generating mechanical work energy of a turbine shaft rotation, which in turn when connected to a generator produces electricity. The steam exiting the turbine is directed towards the condenser where it changes into condensate by losing the heat of evaporation to the cooling system.
