工作原理

Working principle

往復(fù)式燃?xì)獍l(fā)電機(jī)組的主要設(shè)備是燃?xì)獍l(fā)動(dòng)機(jī)和交流發(fā)電機(jī)，并配備進(jìn)氣燃?xì)庀到y(tǒng)、冷卻系統(tǒng)、潤滑系統(tǒng)、控制系統(tǒng)等輔助裝置。以瓦斯發(fā)電為例，其原理是瓦斯氣體進(jìn)入燃?xì)獍l(fā)動(dòng)機(jī)汽缸內(nèi)燃燒，產(chǎn)生的動(dòng)力驅(qū)動(dòng)發(fā)動(dòng)機(jī)曲軸旋轉(zhuǎn)，曲軸將動(dòng)力傳遞給交流發(fā)電機(jī)，發(fā)電機(jī)運(yùn)轉(zhuǎn)后將動(dòng)力轉(zhuǎn)換為電能輸出 。燃燒后產(chǎn)生的高溫?zé)煔?，可排入大氣或送入余熱鍋爐回收熱能再利用。

The main equipment of a reciprocating gas generator set is a gas engine and an AC generator, equipped with auxiliary devices such as an intake gas system, cooling system, lubrication system, and control system. Taking gas power generation as an example, its principle is that gas enters the cylinder of a gas engine and burns, generating power that drives the engine crankshaft to rotate. The crankshaft transmits the power to an AC generator, which then converts the power into electrical energy output. The high-temperature flue gas generated after combustion can be discharged into the atmosphere or sent to a waste heat boiler for heat recovery and reuse.

優(yōu)點(diǎn)

advantage

發(fā)電質(zhì)量優(yōu)：工作時(shí)僅旋轉(zhuǎn)運(yùn)動(dòng)，電調(diào)反應(yīng)迅速，運(yùn)行平穩(wěn)。輸出電壓和頻率精度高、波動(dòng)小，在突加或突減 50% 和 75% 負(fù)載時(shí)，運(yùn)行穩(wěn)定性優(yōu)于柴油發(fā)電機(jī)組。

Excellent power generation quality: only rotating during operation, with rapid response and smooth operation of the electric control system. The output voltage and frequency have high accuracy and small fluctuations. When the load suddenly increases or decreases by 50% and 75%, the operational stability is better than that of diesel generator sets.

啟動(dòng)性能好：冷態(tài)啟動(dòng)成功后到滿負(fù)載僅需 30 秒鐘，能在任何環(huán)境溫度和氣候下保證啟動(dòng)成功率 ，相比之下，國際規(guī)定柴油發(fā)電機(jī)啟動(dòng)成功后 3 分鐘才能帶負(fù)載。

Good starting performance: After successful cold start, it only takes 30 seconds to reach full load, which can ensure the success rate of starting in any environmental temperature and climate. In contrast, international regulations require diesel generators to be loaded after 3 minutes of successful start.

噪聲低振動(dòng)?。喝计啓C(jī)處于高速旋轉(zhuǎn)狀態(tài)，振動(dòng)小，低頻噪聲優(yōu)于柴油發(fā)電機(jī)組。

Low noise and low vibration: The gas turbine is in a high-speed rotating state, with low vibration and better low-frequency noise than diesel generator sets.

燃料清潔廉價(jià)：可使用瓦斯氣、桔梗氣、沼氣等清潔、廉價(jià)的可燃性氣體，不僅運(yùn)行可靠、成本低，還能變廢為寶，減少污染。

Clean and inexpensive fuel: Clean and inexpensive combustible gases such as gas, platycodon gas, biogas, etc. can be used, which not only run reliably and have low costs, but also turn waste into treasure and reduce pollution.
