In China, due to the influence of natural gas supply, natural gas power generation is still in the initial stage. It will take time for a large area of natural gas power generation to become a distributed energy station. Now the small-scale natural gas power generation is mainly in oil fields, gas fields, airports, hotels, hospitals, etc. It can be predicted that with the more abundant natural gas supply and the continuous expansion of the scope of supply, natural gas power generation will get a rapid development in recent years. Gas generator sets also develop with the development of social energy demand. What are the differences between different power machines?

內燃機發(fā)電和蒸汽輪機、燃氣輪機區別：發(fā)電裝置分兩塊：發(fā)電部分和動(dòng)力部分，一般發(fā)電部分都差不多，都是線(xiàn)圈切割磁感線(xiàn)，切割運動(dòng)都是旋轉運動(dòng)，而動(dòng)力部分就有區別了，這就是你要問(wèn)的根本區別。

The difference between internal combustion engine power generation and steam turbine and gas turbine: the power generation device is divided into two parts: the power generation part and the power part. Generally, the power generation part is almost the same, both of which are coil cutting magnetic induction lines, and the cutting motion is rotary motion, while the power part is different. This is the fundamental difference you need to ask.

1、燃氣輪機：壓氣機(即壓縮機)連續地從大氣中吸入空氣并將其壓縮；壓縮后的空氣進(jìn)入燃燒室，與噴入的燃料混合后燃燒，成為高溫燃氣，隨即流入燃氣渦輪中膨脹做功，推動(dòng)渦輪葉輪帶著(zhù)壓氣機葉輪一起旋轉；加熱后的高溫燃氣的做功能力顯著(zhù)提高，因而燃氣渦輪在帶動(dòng)壓氣機的同時(shí)，尚有余功作為燃氣輪機的輸出機械功。燃氣輪機由靜止起動(dòng)時(shí)，需用起動(dòng)機帶著(zhù)旋轉，待加速到能獨立運行后，起動(dòng)機才脫開(kāi)。

1. Gas turbine: the compressor continuously sucks air from the atmosphere and compresses it; The compressed air enters into the combustion chamber, mixes with the injected fuel and burns to become high-temperature gas, and then flows into the gas turbine to expand and do work, driving the turbine impeller and the compressor impeller to rotate together; The work capacity of the heated high-temperature gas is significantly improved, so the gas turbine can drive the compressor while there is surplus work as the output mechanical work of the gas turbine. When the gas turbine starts from a standstill, it needs to be rotated by the starter. The starter will not be disengaged until it can be accelerated to operate independently.

2、內燃機發(fā)電:跟汽車(chē)等都是一樣的，燃料在氣缸內燃燒，燃氣膨脹后推動(dòng)活塞，活塞通過(guò)曲柄凸輪機構傳給曲軸，曲軸做旋轉運動(dòng)，這就可以帶動(dòng)發(fā)電部分了。內燃機發(fā)電設備主要有柴油發(fā)電機組和燃氣發(fā)電機組，燃氣發(fā)電機組又分沼氣發(fā)電機組、天然氣發(fā)電機組、煤氣發(fā)電機組、生物質(zhì)氣發(fā)電機組、瓦斯發(fā)電機組等等。

2. Internal combustion engine power generation: it is the same as automobile. The fuel is burned in the cylinder, and the gas expands to push the piston. The piston is transmitted to the crankshaft through the crank cam mechanism, and the crankshaft rotates, which can drive the power generation part. Internal combustion engine power generation equipment mainly includes diesel generator set and gas generator set. Gas generator set is divided into biogas generator set, natural gas generator set, gas generator set, biomass gas generator set, gas generator set and so on.

3、蒸汽輪機：過(guò)熱蒸汽進(jìn)入到汽輪機，通過(guò)動(dòng)靜葉柵形成的噴嘴作用到轉子上，即將壓力能和熱能轉化為機械能，使轉子旋轉運動(dòng)，同樣可以帶動(dòng)發(fā)電部分了。

3. Steam turbine: superheated steam enters the steam turbine and acts on the rotor through the nozzle formed by the dynamic and static cascades, that is, converting the pressure energy and heat energy into mechanical energy to make the rotor rotate, which can also drive the power generation part.
