What is a Stirling Engine?
Stirling Engine
Stirling Engine is an external combustion heat engine converts heat into usable energy through the expansion and contraction of air or another gas. Unlike car engines (internal combustion), it has an external heat source, allowing it to run on waste heat from things like gas combustion, flue gas, flares etc. It’s known for being efficient, quiet, and adaptable to various heat sources, making it a strong contender for clean energy generation.
Advantages Of Stirling Engines
FUEL AND HEAT SOURCE VERSATILITY
It can operate using various fuels, heat carriers, and heat sources, including nuclear reaction heat, solar energy heat, chemical reaction
SIMPLE STRUCTURE
It has a straightforward design with fewer parts compared to internal combustion engines, comprising only about 40% of the parts of such engines.
TRIGENERATION CAPABILITY
It can produce heat, electricity, and cold simultaneously, enhancing its versatility.
LOW NOISE
During operation, it produces minimal noise, lacking the loud blasts and knocking sounds often associated with other engines.
WIDE RANGE OF APPLICATIONS
The Stirling engine finds diverse applications across various industries due to its fuel adaptability and modular design.
Sources
Heat Sources For Stirling Engine
Solar Heat, including direct solar heat, stored solar heat
Combustible gas, including natural gas, coal gas, syngas, hydrogen, associated gas etc
Fuel oil, including diesel, gasoline, heavy oil, etc
Hot gas, including hot air or chemical reactions
