What is Project Charter?

• It is a written document issued by the project iniciator or sponsor.
• It authorizes/approves the existance of a project.
• It also provides the project manager with the authority to apply organizational resources to project activities.
• It contains the high level information of the project, such as objective, product, service ect.
• The project releted information will be written in brief.

The main parts are as followings:

1. Key stakeholder list

2. Preapproved financial resources.

3. Overall project risk.

4. Project approval requirments.

5. Project exit criteria.

6. Assigner project manager responsibility and authority level.

7. Name and authority of project sponsors.

8. Summary mileston schedule.

Why Should A Steam Or Moisture Separator Be Installed In The Steam Line Next To A Steam Turbine?

All multistage turbines, low-pressure turbines, and turbines operating at high pressure with saturated steam should have a moisture separator in order to prevent rapid blade wear from water erosion.

What Is Meant By Critical Speed?

• It is the speed at which the machine vibrates most violently.
•  It is due to many causes, such as imbalance or harmonic vibrations set up by the entire machine.
  
• To minimize damage, the turbine should be hurried through the known critical speed as rapidly as possible. (Caution, be sure the vibration is caused by critical speed and not by some other trouble).

What Are The Two Basic Types Of Steam Turbines?

1. Impulse type.
2. Reaction type.

What Are Four Types Of Turbine Seals?

1. Carbon rings fitted in segments around the shaft and held together by garter or retainer springs.
2. Labyrinth mated with shaft serration’s or shaft seal strips.
3. Water seals where a shaft runner acts as a pump to create a ring of water around the shaft. Use only treated water to avoid shaft pitting.
4. Stuffing box using woven or soft packing rings that are compressed with a gland to prevent leakage along the shaft.

How Is Oil Pressure Maintained When Starting Or Stopping A Medium-sized Turbine?

An auxiliary pump is provided to maintain oil pressure. Some auxiliary pumps are turned by a hand crank; others are motor-driven. This pump is used when the integral pump is running too slowly to provide pressure, as when starting or securing a medium-sized turbine.

How Is A Flyball Governor Used With A Hydraulic Control?

As the turbine speeds up, the weights are moved outward by centrifugal force, causing linkage to open a pilot valve that admits and releases oil on either side of a piston or on one side of a spring-loaded piston. The movement of the piston controls the steam valves.

What Are Some Conditions That May Prevent A Turbine From Developing Full Power?

1. The machine is overloaded.
2. The initial steam pressure and temperature are not up to design conditions.
3. The exhaust pressure is too high.
4. The governor is set too low.
5. The steam strainer is clogged.
6. Turbine nozzles are clogged with deposits.
7. Internal wear on nozzles and blades.
