Stirling engine advantages
1. Suitable for all kinds of energy sources. Whether it is a liquid, gaseous or solid fuel, when indirectly heated by a heat carrier system (such as a heat pipe), almost any high temperature heat source can be used, such as biomass (firewood, etc.), and the engine itself (except the heater) No need to make any changes at the same time, the hot air machine does not need compressor boost, use the general fan to meet the requirements, and allow the fuel to have higher impurity content; solar energy, which is one of the more common uses of the Stirling engine; radioisotope It is commonly used in AIP systems for submarines and deep spaces.
2. The noise is small. When the hot air machine is running, since the combustion of the fuel is continuous, the knocking work and the intermittent combustion process like the internal combustion engine are avoided, thereby realizing the advantage of low noise. This allows it to be used on submarines for better concealment. The single-machine capacity of the hot air machine is small, and the unit capacity is from 20-50kw, which can increase or decrease the system capacity according to local conditions. The structure is simple, the number of parts is 40% less than that of the internal combustion engine, the price reduction space is large, and the maintenance cost is also low.
3. Not affected by air pressure. This is due to the isolation of the working fluid from the atmosphere in the Stirling closed cycle. This makes it ideal for use at high altitudes.
