燃氣發(fā)電機組的使用優(yōu)勢有哪些?
一、發(fā)電質(zhì)量好
1、 Good power generation quality
由于發(fā)電機組工作時(shí)只有旋轉運動(dòng),電調反應速度快,工作特別平穩,發(fā)電機輸出電壓和頻率的精度高,波動(dòng)小,在突加空減50%和75%負載時(shí),機組運行非常穩定,優(yōu)于柴油發(fā)電機組的電氣性能指標。
Due to the fact that the generator set only rotates during operation, the electrical regulation response speed is fast, and the operation is particularly stable. The accuracy of the generator output voltage and frequency is high, and the fluctuation is small. When suddenly adding 50% and 75% of the load, the unit operates very stably, which is superior to the electrical performance index of diesel generator sets.
二、啟動(dòng)性能好,啟動(dòng)成功率高
2、 Good startup performance and high success rate of startup
從冷態(tài)啟動(dòng)成功后到滿(mǎn)負載的時(shí)間僅為30秒鐘,而規定柴油發(fā)電機啟動(dòng)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(dòng)的成功率。
The time from successful cold start to full load is only 30 seconds, while according to international regulations, the diesel generator is loaded within 3 minutes after successful start. The gas turbine generator set can ensure the success rate of startup under any environmental temperature and climate.
三、噪聲低振動(dòng)小
3、 Low noise and vibration
由于燃汽輪機處于高速旋轉狀態(tài),它的振動(dòng)非常小,而且低頻噪聲優(yōu)于柴油發(fā)電機組。
Due to the high-speed rotation of the gas turbine, its vibration is very small and low-frequency noise is better than that of diesel generator sets.
四、采用的可燃性氣體是清潔、廉價(jià)的能源
4、 The combustible gas used is a clean and inexpensive energy source
諸如:瓦斯氣,桔梗氣,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(huì )產(chǎn)生污染。
Generators that use gas such as gas, campanulin gas, and biogas as fuels not only operate reliably and have low costs, but also turn waste into wealth without generating pollution.
注意事項
matters needing attention
燃氣發(fā)電機組機房需要遠離明火區域,這樣也是為了安全考慮,而且需要寬敞、明亮且要求安裝換氣扇以保證良好的通風(fēng);燃氣發(fā)電機組在安裝底盤(pán)與地基時(shí),需要用平墊鐵找平,另外接觸面積需要在60%以上,且分布均勻;
The gas generator room needs to be away from the open flame area for safety reasons, and it needs to be spacious, bright, and requires the installation of ventilation fans to ensure good ventilation; When installing the chassis and foundation of a gas generator set, it is necessary to level it with a flat iron pad, and the contact area should be over 60% and evenly distributed;
燃氣發(fā)電機組機房室內安裝照明、開(kāi)關(guān)、線(xiàn)路及其電器應該采用防爆措施,且固定牢固,機房?jì)葢舷酪?,配備滅火器等消防器械,燃氣發(fā)電機組機房?jì)刃枰惭b可燃氣體報警裝置,可燃氣體泄露時(shí)能及時(shí)發(fā)現;
The indoor installation of lighting, switches, circuits, and electrical appliances in the gas generator room should adopt explosion-proof measures and be firmly fixed. The room should meet fire protection requirements and be equipped with fire extinguishers and other fire-fighting equipment. Combustible gas alarm devices should be installed in the gas generator room to detect combustible gas leakage in a timely manner;
60kw以下單臺燃氣發(fā)電機組燃氣管路的外部主要管道也是有要求的,內徑應不小于2吋,靠近發(fā)動(dòng)機的部分內徑應不小于1吋。60kw以上燃氣發(fā)電機組則分別是3吋和兩吋,而且需要安裝燃氣閥門(mén)、型放水閥、防回火裝置,燃氣管路焊接完成應清理焊渣,還有一單需要提醒大家,燃氣必須脫硫、脫水、除塵,其中含流量≤0.25Nm3,氫氣≤10%。
There are also requirements for the external main pipelines of the gas pipeline of a single gas generator unit below 60kW, with an inner diameter of no less than 2 inches, and the inner diameter of the part near the engine should be no less than 1 inch. For gas generator units above 60kW, they are 3 inches and 2 inches respectively, and require the installation of gas valves, type drain valves, and anti backfire devices. After welding the gas pipeline, welding slag should be cleaned. There is also a reminder that the gas must be desulfurized, dehydrated, and dusted, with a flow rate of ≤ 0.25Nm3 and hydrogen gas of ≤ 10%.
