Gas Turbine

04/15/2023 4

• It is a type of internal combustion engine

• Basic Operation is similar to that of the steam power plant

• Difference from steam power plant air is used instead of water

Types of Gas Turbine

Turbojet Turbofan

Turboprop Afterbuming Turbojet

• Jet engine in which the jet gases also

operate a turbine-driven compressor for

compressing the air drawn into the engine.

• An aircraft powered by a turbojet.

Turbojet

• A jet engine in which a turbine-driven

fan provides additional thrust.

• An aircraft powered by a turbofan

Turbofan

04/15/2023 9

• A jet engine in which a turbine is used

to drive a propeller.

• An aircraft powered by a turboprop.

Turboprop

• An afterburner or "reheat jet pipe" is a

combustion chamber added to reheat

the turbine exhaust gases.

• Very high fuel consumption

• Four times higher fuel consumption than

that of the main engine.

• Used in supersonic aircraft, most being

military aircraft.

Working of Gas Turbine

04/15/2023 12

• Engine derive its power from burning fuel in a combustion chamber

• It has a second turbine acting as an air compressor mounted on the

same shaft

• The gas turbine is comprised of three main components:

– Compressor

– Combustor

– Turbine

• The working fluid is air

• Air is compressed in the compressor


04/15/2023 13

• Compressed air is mixed with fuel

• Burned by the combustor under constant pressure conditions in

the combustion chamber

• The resulting hot gas expands through the turbine to perform

work

• Much of the power produced in the turbine is used to run the

compressor and do useful work

• The system is an open system

Applications of Gas

Turbines

04/15/2023 16

• Gas turbines are used in many naval vessels, where they are valued

for their high power to weight ratio and their ships resulting

acceleration and ability to get underway quickly.

Marine Application

04/15/2023 17

• To move an airplane through the air, we have to use some kind

of propulsion system to generate thrust.

• The most widely used form of propulsion system for modern

aircraft is the gas turbine engine.

• Turbine engines come in a variety of forms.

• Micro gas turbines are used in BLADON JET ENGINE.

Jet Application

04/15/2023 18

• Bladon Jet Engine is a new generation of green and quiet efficient

power units.

• Their small size, light weight and high output deliver significant

advantages over traditional reciprocating engines.

Bladon Jet Engine

04/15/2023 19

• The use of gas turbines for generating electricity dates back to 1939

• Today, gas turbines are one of the most widely-used power

generating technologies

• Installations of such turbine not normally

used for base load electricity generation

but for bringing power to remote sites such as oil and gas fields

• Such turbines can produce power up to 5MW to 500MW
