HISTORYInventor = Robert

Stirling (1790 - 1878)Sought to replace the

steam turbines of his days

due to frequent explosion

caused by unsustainablehigh pressure killing and

injuring workers

Invented Stirling engine in

1816 which could not

explode and produce more

power then the steam

engine used.

STIRLING ENGINE

Device that converts heat energy to mechanicalpower by alternately compressing and expandinga fixed quantity of working fluid at differenttemperatures.

Regeneration as alternative.

WHY STIRLING ENGINE?

Best teaching and learning for any engineering

students device especially in the field of

thermodynamics.

Unique technology.

An innovation with hundreds of application.

An innovation with a mission to save the earth.Fuel independency.

With out fuels to function.

MAIN COMPONENTSPower piston small tightly sealed piston that

moves up when the gas inside the engine expandsDisplacer larger piston and it is very loose in its

cylinder so air can move easily between the heatedcooled sections of the engine as the displacer moves

up and down

These piston move by the action of compression andexpansion.

Difference in pressure causes the piston to moveand produce power.

WORKING PRINCIPLE

I. One side of the engine is continuously rotated bymotor.

II. First, when the piston moves BDC to TDC, the air is

compressed inside the cylinder.

III. Then the air moves through the regenerator to the

cold side, where it cools off and contracts pulling

down on the piston.

IV. Temperature change inside the engine produces the

pressure change needed to push on the piston and

make the engine run.

ADVANTAGES

Various heat sources (solar, geothermal, nuclearenergy, waste heat, biological)

Environmental friendly

Heat is external and the burning of a fuel-airmixture can be more accurately controlled.

Operates at relatively low pressure and thus are

much safer than typical steam turbinesLess manpower needed to operate any type of

commercial Stirling engine.

APPLICATION

WATER PUMP STATION

A Stirling engine used for

pumping water can be

configured so that the water

cools the compression space.

This is most effective whenpumping cold water.

STIRLING CYROCOOLERS Any Stirling engine will also work in reverse as a

heat pump. When a motion is applied to the shaft, a

temperature difference appears between the

reservoirs.

NUCLEAR POWER

Replacing the steam turbines of the nuclear power

plant with Stirling engine might simplify the plant,yield greater efficiency, and reduce the radioactivity

by products.

CONCLUSION

Unlimited source of heat source

Political awareness of green heat and power

production.

Large market experiencing rapid growth.

Many different possible applications.

Time to change.
