IGT SA5.0 Starting Equipment - Part 2

What is the first step in starting a gas turbine?

• Engaging the fuel system

• Cranking the turbine

• Checking the oil levels

• Monitoring exhaust temperatures

What is referred to as 'breakaway' in turbine operations?

• The moment combustion starts

• Initiating rotation from a standstill

• Disengaging the starting device

• Cooling down the turbine

When does the starting device disengage from the turbine?

• Once the turbine reaches firing speed

• Immediately after starting

• When the combustion chamber cools

• After the first hour of operation

What is the function of the hydraulic system in turbine start-up?

• To provide fuel to the combustion chamber

• To assist in cranking the turbine

• To regulate exhaust temperatures

• To cool the turbine after shutdown

What is a significant advantage of using a torque converter in turbine applications?

• It reduces the weight of the system

• It allows independent spinning of the gas turbine

• It improves fuel efficiency

• It minimizes maintenance needs

Which principle explains how hydraulic systems operate?

• Newton's laws of motion

• Bernoulli's principle

• Pascal's principle

• Archimedes' principle

What type of pressure does a pneumatic starter utilize?

• Low pressure

• Atmospheric pressure

• High pressure

• Variable pressure

Which system is critical for preventing backslip during operation?

• Cooling system

• Fuel system

• Hydraulic ratchet system

• Exhaust system

What is the primary purpose of a hydraulic ratchet during operation?

• To increase fuel efficiency

• To assist with starting the gas turbine

• To maintain rotor position

• To regulate airflow

What does the torque converter adjust as the rotor accelerates?

• Temperature control

• Fuel supply

• Torque transfer

• Exhaust flow
