The ATE FPSG Acoustic Stirling Engine

Based on work performed at NASA we have enhanced our stirling engine and designed an acoustic 200kWe prototype: The AS (Acoustic Stirling) Engine.

Power output up to 250 kW

Inlet pressure up to 40 bar(a)/580 psi

Inlet temperature molten salt up to 650 °C

MS Outlet Temperature >150oC

Water inlet for cooling

Dimension

Length 1.5 m

Width 1.5 m

A: Displacer Piston in position zero; Power Piston in position zero.

B: Displacer move down and press air on Power Piston moving it down

C: Hot air moved away from Displacer Top, Cold Air are pressed up

Efficient conversion of energy
