What conditions will affect the efficiency of Stirling engine?
The Stirling engine performance depends on geometrical and physical characteristics of the engine and on the working fluid gas properties such as regenerator efficiency and porosity, dead volume, swept volume, temperature of sources, pressure drop losses, and shuttle losses.
How efficient can Stirling engines get?
The Application of Stirling Engines for Power Generation
In solar thermal applications a Stirling engine could theoretically achieve close to 40% energy conversion efficiency. The best so far recorded is 32% which is still high for solar conversion.
How much energy can a Stirling engine produce?
generating between 200-500 watts of electricity. Several designs were studied before settling on an alpha type configuration based around a two-cylinder air compressor.
What oil do you use in a Stirling engine?
High temperature lubricant is a synthetic substance specifically designed for use on your Stirling engine. Accordingly it’s advisable to only use this product for optimum performance.
Why is the Stirling engine inefficient?
Stirling’s original design involved a rather complicated double-piston mechanism that caused friction losses. Furthermore, the necessary heat exchangers reduce the efficiency in comparison to internal combustion engines.
Are Stirling engines more efficient than solar panels?
Stirling engines are significantly more efficient at converting sunlight into energy than most photovoltaic panels or concentrating solar power plants, whether parabolic trough or tower designs.
Why don’t we use Stirling engines?
Here’s the Short Answer: Stirling engines are not good for applications that need to change their power output levels quickly, like cars for example. … Plus, they tend to be heavier (and more expensive) than gasoline or diesel engines of a similar power output.
What is the advantage of Stirling engine?
The main advantages of Stirling engines are the ability to use various heat sources and combustion chambers meeting environmental requirements, a low level of noise and vibration; favorable characteristics for both vehicles and stationary electric generators, and good consistency with a linear electric machine.
