燃氣發電機組：發電機組，用天然氣和柴油那種更省？
我們都知道，常用的大型發電機組，根據使用燃料的不同，主要有柴油發電機組、燃氣發電機組兩大類。這兩種到底哪種更好，答案見仁見智；但要說哪種更省，我們還是用數據說話。
We all know that the commonly used large generator sets mainly include diesel generator sets and gas generator sets according to the different fuels used. The answer to which of these two is better is subjective; But when it comes to which one is more cost-effective, we still speak with data.
每度電花多少錢

不同的機組，發1度電用多少燃料？具體要多少錢？我們先來看天然氣：
How much fuel does different units use to generate 1 kWh of electricity? How much does it cost specifically? Let's first take a look at natural gas:
根據相關數據，天然氣熱值為8400Cal/m3，我們按照正常燃燒效率85%計算，那么每立方米天然氣燃燒后可以產出約8400*85%/860=8.302kw/m3的熱量。
According to relevant data, the calorific value of natural gas is 8400Cal/m3. Based on a normal combustion efficiency of 85%, each cubic meter of natural gas can produce approximately 8400 * 85%/860=8.302kw/m3 of heat after combustion.
環能的燃氣發電機組平均發電效率約為40%計算，則發電量為3.321kw/m3，也就是說，環能燃氣發電機組每立方米天然氣大概可以發電3.321度。
The average power generation efficiency of the gas generator set of Huaneng is about 40%. Therefore, the power generation capacity is 3.321 kW/m3, which means that the Huaneng gas generator set can generate approximately 3.321 kWh of electricity per cubic meter of natural gas.
目前國內市場的非居民用天然氣價格基本穩定在為3.1元/m3左右，則每發1度電成本為3.1/3.321=1.03元。
At present, the price of natural gas for non residential use in the domestic market is basically stable at around 3.1 yuan/m3, so the cost of generating 1 kWh of electricity is 3.1/3.321=1.03 yuan.
再來看柴油機組。根據同樣的計算方式可以得出，1升柴油可發電3.3-4.4度，當前的柴油價格為7.5元/L左右，那么柴油發電機組每發1度電的所花費的燃料成本則為1.7~2.3元。
Let's take a look at the diesel engine set again. According to the same calculation method, 1 liter of diesel can generate 3.3-4.4 kWh of electricity. The current diesel price is around 7.5 yuan/L. Therefore, the fuel cost for each kWh of electricity generated by a diesel generator set is 1.7-2.3 yuan.
顯然，用柴油發電機組發電，僅燃料費就比用燃氣多了一倍之多！
Obviously, using a diesel generator set to generate electricity incurs fuel costs that are twice as much as using gas alone!

發電燒氣還是燒柴油，這是個問題。既然燃氣發電機組這么省，它還有哪些優點？
Whether to burn gas or diesel for power generation is a question. Since gas generators are so economical, what are their other advantages?
污染少，更環保
Less pollution, more environmentally friendly
天然氣燃燒后，理論上只有二氧化碳和水，不排放污染物；而柴油燃燒后除了那滾滾濃煙，還可能產生一氧化碳、二氧化氮、二氧化硫等廢氣。
After natural gas combustion, theoretically only carbon dioxide and water are emitted, and no pollutants are emitted; After diesel combustion, in addition to the thick smoke, it may also produce exhaust gases such as carbon monoxide, nitrogen dioxide, and sulfur dioxide.
如果在對環保有要求的場景，如住宅區、景區、醫院等地，燃氣發電機組顯然更好一些。
If there are environmental requirements in scenarios such as residential areas, scenic spots, hospitals, etc., gas generators are obviously better.
環境適應力更強
Stronger environmental adaptability
環能的燃氣機組可在-40℃~55℃正常工作，低溫啟動能力更強，啟動成功率也高。而柴油機組如果在低溫環境下，還需要相當多的準備工作才能啟動。后者在運維保養方面要求更高，而前者則要小很多。
The gas turbine unit of Huanneng can operate normally at -40 ℃~55 ℃, with stronger low-temperature starting ability and a high success rate of starting. If the diesel generator set is operated in a low-temperature environment, it still requires a considerable amount of preparation work to start. The latter has higher requirements for operation and maintenance, while the former is much smaller.
如果進一步將普通燃氣發電機組升級為環能集裝箱式發電站，通過箱體內多種不同功能的配置，則可以進一步增強機組的環境適應能力，酷寒、風沙、炎熱、多雨等氣候均能輕松應對。
If the ordinary gas generator set is further upgraded to an environmental energy containerized power station, with various functions configured inside the box, the environmental adaptability of the unit can be further enhanced, and it can easily cope with climates such as extreme cold, sandstorms, heat, and rain.
使用成本更低
Lower usage cost
與傳統柴油發電機組相比，環能燃氣機組除了用天然氣等燃氣的成本更低之外，燃氣機組可以使用更低水平的潤滑，燃氣對設備的損耗也更低，相應地也就延長了機組整體的維修周期，從而降低了成本。
Compared with traditional diesel generator sets, environmental energy gas generators not only have lower costs of using natural gas and other gases, but also can use lower levels of lubrication, resulting in lower equipment losses caused by gas. As a result, the overall maintenance cycle of the generator set is extended, thereby reducing costs.
再加上環能具有自主知識產權的智能控制系統，利用數字技術控制機組，自動啟動、自動保護、自動切換，并且還可以遠程操控，又可以進一步縮減運維成本。
In addition, Huaneng has an intelligent control system with independent intellectual property rights, which uses digital technology to control the unit, automatically starts, protects, switches, and can also be remotely controlled, further reducing operation and maintenance costs.
此外，環能燃氣發電機組選用先進發動機，配以高性能減震系統，震動小、噪音低，并能有效地控制發動機的混合比，使熱效率高，在降低使用成本的他同時，還提供了更優越的使用體驗。
In addition, the environmental energy gas generator set uses advanced engines and is equipped with high-performance shock absorption systems, which have low vibration and noise, and can effectively control the mixing ratio of the engine, resulting in high thermal efficiency. While reducing operating costs, it also provides a superior user experience.
正因為環能燃氣發電機組卓越的性能，才使得機組可以用作備用和主用發電機組使用，作為冷熱電三聯供機組、調峰電站、邊井站、其他分布式電源等場合。
It is precisely because of the excellent performance of the environmental energy gas generator set that the unit can be used as a backup and main generator set, as a combined cooling, heating and power unit, peak shaving power station, side well station, and other distributed power sources.
