由于受到天然氣供應(yīng)的影響，天然氣發(fā)電尚處于初始階段。真正大面積的天然氣發(fā)電作為分布能源站還要假以時(shí)日。現(xiàn)在的小規(guī)模天然氣發(fā)電主要是在油田、氣田以及機(jī)場、酒店、醫(yī)院等。可以預(yù)計(jì)，隨著天然氣供應(yīng)的愈加充足、供應(yīng)范圍的不斷擴(kuò)大，近幾年天然氣發(fā)電將會(huì)得到一個(gè)飛速的發(fā)展。燃?xì)獍l(fā)電機(jī)組也借助社會(huì)能源需求的發(fā)展而發(fā)展，不同的動(dòng)力機(jī)械存在什么差別呢？

Due to the impact of natural gas supply, natural gas power generation is still in its initial stage. It will take time for large-scale natural gas power generation to become a distributed energy station. The current small-scale natural gas power generation is mainly in oil fields, gas fields, as well as airports, hotels, hospitals, etc. It can be expected that with the increasing supply of natural gas and the continuous expansion of the supply range, natural gas power generation will experience rapid development in recent years. Gas generator sets have also developed with the help of social energy demand. What are the differences between different power machinery?

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/gas turbine: The power generation device is divided into two parts: the power generation part and the power generation part. Generally, the power generation part is similar, with coils cutting magnetic induction lines and cutting motion being rotational motion, while the power generation 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 draws in air from the atmosphere and compresses it; The compressed air enters the combustion chamber, mixes with the injected fuel, and burns to become high-temperature gas, which then flows into the gas turbine to expand and do work, pushing the turbine impeller to rotate together with the compressor impeller; The work capacity of the heated high-temperature gas is significantly improved, so the gas turbine not only drives the compressor, but also has surplus work as the output mechanical work of the gas turbine. When a gas turbine is started from a stationary state, it needs to be driven by a starter motor to rotate. The starter motor will only disengage when it accelerates to independent operation.

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: Similar to cars, fuel is burned in the cylinder, and the gas expands to push the piston. The piston is transmitted to the crankshaft through a crank cam mechanism, and the crankshaft rotates to drive the power generation part. Internal combustion engine power generation equipment mainly includes diesel generator sets and gas generator sets. Gas generator sets are further divided into biogas generator sets, natural gas generator sets, gas generator sets, biomass gas generator sets, gas generator sets, 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: Overheated steam enters the turbine and acts on the rotor through nozzles formed by the dynamic and static blades, converting pressure energy and heat energy into mechanical energy, causing the rotor to rotate and move, and also driving the power generation part.
