IGT PO5.1-5.4

What is the primary function of a turbine starting device?

• To supply high torque at zero speed

• To cool down the turbine

• To monitor fuel levels

• To increase air pressure

Which of the following is NOT a type of turbine starting device?

• Pneumatic starter

• Hydraulic pump

• Diesel engine

• Electric motor start

What does a hydraulic ratchet system assist with during turbine operation?

• Cooling the rotor

• Starting the turbine

• Monitoring fuel consumption

• Locking blades in place

Which starting device is commonly used for larger gas turbines?

• AC Electric Motor

• Manual start

• Inlet Bleed air start

• Battery start

What is the role of a torque converter in a gas turbine system?

• To multiply torque during startup

• To provide cooling to the turbine

• To reduce emissions

• To monitor fuel efficiency

What is the first step before a gas turbine can be fired?

• It must be rotated by an outside source

• It must be cooled down

• It must be inspected for damage

• It must be filled with fuel

What type of starting device uses high-pressure gas?

• Steam turbine

• Electric motor

• Diesel engine

• Pneumatic starter

What happens when the turbine reaches self-sustaining speed?

• The cooling system activates

• The starting device is disengaged

• The turbine shuts down

• The fuel supply is cut off

What is the purpose of overcoming mechanical inertia during start-up?

• To ensure proper fuel combustion

• To initiate rotation of the turbine

• To cool the turbine components

• To monitor the system pressure

Which starting device is used when there is no power supply?

• Hydraulic start

• Pneumatic starter

• Electric motor

• Diesel engine
