燃氣發(fā)電機組具有輸出功率范圍廣，啟動和運行可靠高、發(fā)電質(zhì)量好、重量輕、體積小、維護簡單、低頻噪聲小等優(yōu)點，一般它們具有以下四個優(yōu)點：
Gas generator units have the advantages of wide range of output power, high reliability of startup and operation, good power generation quality, light weight, small volume, simple maintenance, low low frequency noise, etc. Generally, they have the following four advantages:
一、發(fā)電質(zhì)量好
1、 Good power generation quality
由于發(fā)電機組工作時只有旋轉(zhuǎn)運動，電調(diào)反應(yīng)速度快，工作特別平穩(wěn)，發(fā)電機輸出電壓和頻率的精度高，波動小，在突加空減50%和75%負載時，機組運行非常穩(wěn)定，優(yōu)于柴油發(fā)電機組的電氣性能指標。
Because the generator set operates only in rotating motion, the electric regulation response speed is fast, the operation is particularly stable, the accuracy of the generator output voltage and frequency is high, and the fluctuation is small. When the load is suddenly increased by 50% and 75%, the operation of the generator set is very stable, which is superior to the electrical performance index of the diesel generator set.
二、啟動性能好，啟動成功率高
2、 Good startup performance and high startup success rate
從冷態(tài)啟動成功后到滿負載的時間僅為30秒鐘，而規(guī)定柴油發(fā)電機啟動成功后3分鐘帶負載。燃氣輪發(fā)電機組可以任何環(huán)境溫度和氣候下保證啟動的成功率。
The time from successful cold start to full load is only 30 seconds, while the international regulations stipulate that the diesel generator is loaded 3 minutes after successful start. The gas turbine generator set can guarantee the success rate of startup under any ambient temperature and climate.
三、噪聲低振動小
3、 Low noise and vibration
由于燃汽輪機處于高速旋轉(zhuǎn)狀態(tài)，它的振動非常小，而且低頻噪聲優(yōu)于柴油發(fā)電機組。
Because the gas turbine is rotating at high speed, its vibration is very small, and its low-frequency noise is better than that of diesel generator set.
四、采用的可燃性氣體是清潔、廉價的能源
4、 The combustible gas used is clean and cheap energy
諸如：瓦斯氣，桔桿氣，沼氣等，以它們?yōu)槿剂系陌l(fā)電機組不僅運行可靠，成本低，而且能變廢為寶，不會產(chǎn)生污染.

For example, gas, orange stem gas, biogas and so on. The generator set fueled by them is not only reliable in operation and low in cost, but also can turn waste into treasure without pollution
燃氣發(fā)電機組由燃氣發(fā)動機、發(fā)電機、控制柜等部件組成,燃氣發(fā)動機與發(fā)電機安裝在同一個鋼制底盤上。機組以天然氣、井口伴生氣、煤礦瓦斯氣、水煤氣、煉化尾氣、沼氣、焦爐煤氣、高爐煤氣等可燃性氣體為燃料,啟動迅速,經(jīng)濟性好,特別是由于高質(zhì)量城市生活的需求,燃氣發(fā)電機組已廣泛應(yīng)用于電信、郵局、銀行、圖書館、醫(yī)院、賓館等部門,作為后備電源。
The gas generator set consists of gas engine, generator, control cabinet and other components. The gas engine and generator are installed on the same steel chassis. The unit is fueled by combustible gases such as natural gas, wellhead associated gas, coal mine gas, water gas, refining tail gas, biogas, coke oven gas, blast furnace gas, etc. It is quick to start and has good economy. Especially due to the demand of high-quality urban life, the gas generator unit has been widely used in telecommunications, post offices, banks, libraries, hospitals, hotels and other departments as a backup power supply.
燃氣發(fā)電機組是針對礦場工況設(shè)計的,機組運行時產(chǎn)生的噪聲一般為95~110 dB(A)。GB 3096-93城市區(qū)域環(huán)境噪聲標準對市區(qū)的噪聲狀況進行了嚴格的規(guī)定,對于2類區(qū)域(居住、商業(yè)、工業(yè)混雜區(qū))晝間為60 dB(A),夜間為50dB(A);對于1類區(qū)域(居住、文教機關(guān)區(qū))晝間為55 dB(A)、夜間為45 dB(A)。
The gas generator unit is designed for the mine conditions, and the noise generated by the unit during operation is generally 95~110 dB (A). GB 3096-93 Environmental Noise Standard for Urban Areas has strict regulations on the noise situation in urban areas. For Class 2 areas (residential, commercial and industrial mixed areas), the noise level is 60 dB (A) in the daytime and 50 dB (A) at night; 55 dB (A) in the daytime and 45 dB (A) at night for Class 1 areas (residential, cultural and educational institutions).
機組運行時產(chǎn)生的噪聲給城市環(huán)境帶來了嚴重的噪聲污染,影響了人們的正常工作和生活,也限制了燃氣發(fā)電機組的廣泛應(yīng)用。本文就是針對燃氣發(fā)電機組噪聲污染問題,提出了一套整改措施,以期降低機組噪聲,促進燃氣發(fā)電機組的推廣應(yīng)用。
The noise generated by the unit operation has brought serious noise pollution to the urban environment, affected people's normal work and life, and also restricted the wide application of gas generator units. This paper proposes a set of rectification measures to reduce the noise pollution of gas generating units and promote the popularization and application of gas generating units.
