• True

• False

Staged combustion allows for better control of temperature and emissions.

• True

• False

Improved combustion efficiency results in increased fuel consumption.

• True

• False

Dry Low NOx burners are used to minimize emissions while maintaining good combustion.

• True

• False

What is the main goal of improving combustion efficiency?

• Increase engine noise

• Burn less air

• Maximize fuel burn and minimize waste

• Decrease engine speed

Which method improves air-fuel mixing for efficient combustion?

• Using low-speed turbines

• Adding water to fuel

• Swirlers and pre-mixers

• Removing the exhaust system

What problem does lean-burn combustion help reduce?

• Vibration

• NOx emissions

• Fuel tank pressure

• Exhaust duct size

Staged combustion divides the combustor into:

• Two compressors

• High and low-pressure sections

• Primary and secondary combustion zones

• Turbine and gearbox

Which system adjusts combustion conditions in real time?
