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(nèi)燃機(jī)發(fā)電和蒸汽輪機(jī)、燃?xì)廨啓C(jī)區(qū)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，都是線圈切割磁感線，切割運(yùn)動(dòng)都是旋轉(zhuǎn)運(yùn)動(dòng)，而動(dòng)力部分就有區(qū)別了，這就是你要問的根本區(qū)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?xì)廨啓C(jī)：壓氣機(jī)(即壓縮機(jī))連續(xù)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?xì)?，隨即流入燃?xì)鉁u輪中膨脹做功，推動(dòng)渦輪葉輪帶著壓氣機(jī)葉輪一起旋轉(zhuǎn)；加熱后的高溫燃?xì)獾淖龉δ芰︼@著提高，因而燃?xì)鉁u輪在帶動(dòng)壓氣機(jī)的同時(shí)，尚有余功作為燃?xì)廨啓C(jī)的輸出機(jī)械功。燃?xì)廨啓C(jī)由靜止起動(dòng)時(shí)，需用起動(dòng)機(jī)帶著旋轉(zhuǎn)，待加速到能獨(dú)立運(yùn)行后，起動(dòng)機(jī)才脫開。

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(nèi)燃機(jī)發(fā)電:跟汽車等都是一樣的，燃料在氣缸內(nèi)燃燒，燃?xì)馀蛎浐笸苿?dòng)活塞，活塞通過曲柄凸輪機(jī)構(gòu)傳給曲軸，曲軸做旋轉(zhuǎn)運(yùn)動(dòng)，這就可以帶動(dòng)發(fā)電部分了。內(nèi)燃機(jī)發(fā)電設(shè)備主要有柴油發(fā)電機(jī)組和燃?xì)獍l(fā)電機(jī)組，燃?xì)獍l(fā)電機(jī)組又分沼氣發(fā)電機(jī)組、天然氣發(fā)電機(jī)組、煤氣發(fā)電機(jī)組、生物質(zhì)氣發(fā)電機(jī)組、瓦斯發(fā)電機(jī)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(jī)：過熱蒸汽進(jìn)入到汽輪機(jī)，通過動(dòng)靜葉柵形成的噴嘴作用到轉(zhuǎn)子上，即將壓力能和熱能轉(zhuǎn)化為機(jī)械能，使轉(zhuǎn)子旋轉(zhuǎn)運(yùn)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.
