SEOUL, Nov. 29 (Korea Bizwire) –
Korean scientists have localized Stirling engine technology, generating electricity along with heat from a home boiler.
The Korea Institute of Machinery and Materials (KIMM) announced on November 27 that it had developed a Stirling engine generator capable of producing not only hot water, but also up to 1kilowatt of electricity from a home boiler.
Stirling engines, unlike internal combustion engines that generate power through ignition and explosion, use heat to produce power, and are called clean engines as they emit less noise and toxic gases. The Stirling engine, with a closed-cylinder filled with helium or hydrogen, operates pistons by heating the gases.
The newly developed Stirling engine can produce 1KW of electricity through a two-way linear generator. Existing 1KW-class Stirling generators being produced by a couple of companies are mainly installed with one-way linear generator.
