  山西瓦斯發(fā)電機(jī)組實(shí)錄!環(huán)能機(jī)型硬核發(fā)力,晉城廢瓦斯變電能,見(jiàn)證能源革命

  Real record of Shanxi gas generator set! Environmental energy model hard core power, Jincheng waste gas converted into electricity, witnessing the energy revolution

  扎根山西晉城,外有萬(wàn)里黃河環(huán)繞,內(nèi)有八百里太行山矗立,這片藏著無(wú)盡煤炭資源的土地,曾被一個(gè)“心腹大患”困擾——煤礦瓦斯。做煤炭行業(yè)的老兵都知道,瓦斯是原煤開采時(shí)的巨大安全隱患,以前晉城的煤礦,沒(méi)好的處理辦法,只能把瓦斯直接燃燒排放,不僅浪費(fèi)資源,還產(chǎn)生大量碳排放和氮氧化物,污染環(huán)境。而這場(chǎng)山西能源革命的核心,正是讓“奪命瓦斯”變廢為寶,而扛起這份重任的,就是瓦斯發(fā)電機(jī)組,今天就結(jié)合晉城的真實(shí)歷程,嘮嘮瓦斯發(fā)電機(jī)組的硬核實(shí)力,純實(shí)干干貨,看完讀懂它如何改寫山西能源格局。

  Rooted in Jincheng, Shanxi, surrounded by thousands of miles of the Yellow River and 800 miles of the Taihang Mountains standing tall, this land, which harbors endless coal resources, was once plagued by a "major problem" - coal mine gas. Veterans in the coal industry know that gas is a huge safety hazard during raw coal mining. In the past, coal mines in Jincheng had no good solution and could only directly burn and discharge gas, which not only wasted resources but also produced a large amount of carbon emissions and nitrogen oxides, polluting the environment. The core of this Shanxi energy revolution is to turn the "deadly gas" into treasure, and the one who shoulders this responsibility is the gas generator set. Today, based on the real process of Jincheng, we will talk about the hard core strength of gas generator sets, pure practical knowledge, and read and understand how it rewrites the Shanxi energy pattern.

  先跟大家說(shuō)句實(shí)在的,2024年山西為中國(guó)提供了超四分之一的原煤產(chǎn)量,可瓦斯難題,曾是煤炭行業(yè)的“心頭刺”。直到2006年,山西金駒煤電化有限責(zé)任公司挺身而出,籌建當(dāng)時(shí)世界單廠裝機(jī)規(guī)模最大的瓦斯發(fā)電廠——沁水寺河120兆瓦瓦斯發(fā)電廠,而支撐這座電廠的核心,就是一臺(tái)臺(tái)環(huán)能瓦斯發(fā)電機(jī)組,這也是山西瓦斯變電能的第一步,更是一場(chǎng)實(shí)打?qū)嵉墓?jiān)。

  To be honest with everyone, Shanxi will provide over a quarter of China's raw coal production in 2024, but the gas problem was once a thorn in the side of the coal industry. Until 2006, Shanxi Jinju Coal to Electricity Co., Ltd. stepped forward to build the world's largest single plant installed capacity gas power plant at that time - the Qinshui Sihe 120 MW gas power plant. The core supporting this power plant was a series of environmental energy gas generator units, which was also the first step in Shanxi's gas to electricity transformation and a practical battle.

  19年前,建設(shè)團(tuán)隊(duì)剛扎根沁水寺河時(shí),這里還是一片荒山野嶺,大家只能租住在附近農(nóng)村的閑置房里,生活條件艱苦到難以想象,但沒(méi)人退縮。這座電廠總共有四個(gè)單元廠房,每個(gè)廠房都配有15臺(tái)環(huán)能發(fā)電機(jī)組,清一色的硬核裝備,核心任務(wù)就是把煤礦開采中產(chǎn)生的瓦斯,轉(zhuǎn)化成可利用的電能和熱能,徹底打破“瓦斯只能浪費(fèi)”的困境。

  19 years ago, when the construction team first rooted themselves in the Qinshui Temple River, it was still a barren mountain range where people could only rent idle houses in nearby rural areas. The living conditions were unimaginable, but no one backed down. This power plant has a total of four unit buildings, each equipped with 15 environmental energy generator units, all of which are hard core equipment. The core task is to convert the gas generated during coal mining into usable electrical and thermal energy, completely breaking the dilemma of "gas can only be wasted".

  可能有老鐵會(huì)問(wèn),瓦斯發(fā)電機(jī)組到底憑啥能搞定這“麻煩事”?就說(shuō)沁水寺河電廠的環(huán)能機(jī)型,它不像普通發(fā)電機(jī)組那樣燒煤、燒油,專門“吃”煤礦廢瓦斯,把瓦斯中的甲烷轉(zhuǎn)化為電能,相當(dāng)于“變廢為寶”。而且它的適配性極強(qiáng),不管是高濃度還是后來(lái)的低濃度瓦斯,都能穩(wěn)定發(fā)力,這也是它能扛起山西能源革命大旗的關(guān)鍵。

  An old railway may ask, why on earth can gas generator set solve this "trouble"? Speaking of the environmental energy model of Qinshui Sihe Power Plant, it does not burn coal or oil like ordinary generator sets. It specializes in "eating" coal mine waste gas and converting methane in the gas into electricity, which is equivalent to "turning waste into treasure". And its adaptability is extremely strong, whether it is high concentration or later low concentration gas, it can steadily exert force, which is also the key to it being able to shoulder the banner of Shanxi's energy revolution.

  2007年下半年,項(xiàng)目進(jìn)入緊張的機(jī)組調(diào)試階段,金駒一線技術(shù)團(tuán)隊(duì)、華北立新航機(jī)械服務(wù)團(tuán)隊(duì)和環(huán)能比勒專家組,日夜不停連軸轉(zhuǎn),攻克了一個(gè)又一個(gè)技術(shù)難題,終于在2008年3月28號(hào),第一臺(tái)環(huán)能瓦斯發(fā)電機(jī)組成功并網(wǎng)發(fā)電。同年10月,沁水寺河瓦斯發(fā)電廠正式投入商業(yè)運(yùn)行,每年發(fā)電量能達(dá)到8.4億千瓦時(shí)以上,相當(dāng)于節(jié)約標(biāo)準(zhǔn)煤約360萬(wàn)噸,成效肉眼可見(jiàn)。

  In the second half of 2007, the project entered a tense stage of unit commissioning. The front-line technical team of Jinju, the mechanical service team of North China Lixin Aviation, and the expert group of Huanneng Beile worked day and night to overcome one technical problem after another. Finally, on March 28, 2008, the first Huanneng gas generator set was successfully connected to the grid for power generation. In October of the same year, the Qinshui Sihe Gas Power Plant was officially put into commercial operation, with an annual power generation capacity of over 840 million kilowatt hours, equivalent to saving about 3.6 million tons of standard coal, and the results are visible to the naked eye.

  一臺(tái)設(shè)備的靠譜,不僅看運(yùn)行,更看后期維護(hù)。沁水寺河電廠的60臺(tái)環(huán)能發(fā)電機(jī)組,在穩(wěn)定運(yùn)行十萬(wàn)多小時(shí)后,進(jìn)入了關(guān)鍵的大修節(jié)點(diǎn)。要是按常規(guī)維修,不僅耗時(shí)久,還會(huì)影響發(fā)電進(jìn)度,金駒團(tuán)隊(duì)和華北立新航機(jī)械服務(wù)團(tuán)隊(duì)反復(fù)研究,最終確定了環(huán)能彼勒再制造的短鋼體維修方案,既最大程度縮短了維修時(shí)間,又實(shí)現(xiàn)了綠色環(huán)保,不得不說(shuō),瓦斯發(fā)電機(jī)組的后期保障,也是山西能源革命能持續(xù)推進(jìn)的底氣。

  The reliability of a device depends not only on its operation, but also on its later maintenance. After more than 100000 hours of stable operation, the 60 environmental energy generator units of Qinshui Sihe Power Plant have entered a critical overhaul phase. If maintenance is carried out as usual, it will not only take a long time, but also affect the power generation schedule. The Jinju team and the North China Lixin Aviation Machinery Service team have repeatedly studied and finally determined the short steel body maintenance plan for the remanufacturing of Huanneng Beile, which not only minimizes maintenance time but also achieves green environmental protection. It has to be said that the later guarantee of gas generator sets is also the confidence for the continuous promotion of Shanxi's energy revolution.

  隨著低濃度瓦斯發(fā)電時(shí)代的到來(lái),山西瓦斯發(fā)電機(jī)組也迎來(lái)了新升級(jí),蘆家峪瓦斯智慧電站就是最好的見(jiàn)證——它是全國(guó)首座搭載智慧平臺(tái)的瓦斯電站,里面共裝有16臺(tái)環(huán)能低濃瓦斯發(fā)電機(jī)組,所有運(yùn)行數(shù)據(jù)都實(shí)現(xiàn)了三維可視化,操作更精準(zhǔn)、運(yùn)行更穩(wěn)定,每年發(fā)電量能達(dá)到1.4億度,讓瓦斯發(fā)電邁入了智慧新時(shí)代。

  With the arrival of the era of low concentration gas power generation, Shanxi's gas power generation units have also undergone new upgrades. The Lujiayu Gas Smart Power Station is the best witness - it is the first gas power station in China to be equipped with a smart platform, with a total of 16 environmental energy low concentration gas power generation units installed inside. All operating data has been visualized in three dimensions, with more accurate operation and more stable operation. The annual power generation can reach 140 million kWh, ushering in a new era of smart gas power generation.

  很多老鐵不了解,瓦斯發(fā)電機(jī)組的核心優(yōu)勢(shì),就是“安全+環(huán)保+盈利”三者兼顧。以前瓦斯直接燃燒,不僅污染環(huán)境,還存在安全隱患;而瓦斯發(fā)電機(jī)組運(yùn)行時(shí),會(huì)先收集瓦斯,避免瓦斯泄漏帶來(lái)的風(fēng)險(xiǎn),發(fā)電過(guò)程中產(chǎn)生的廢氣經(jīng)過(guò)處理后排放,大幅減少碳排放,契合低碳發(fā)展的要求。

  Many old railways do not understand that the core advantage of gas generating units is "safety+environmental protection+profitability". Previously, direct combustion of gas not only polluted the environment but also posed safety hazards; When the gas generator set is in operation, gas will be collected first to avoid the risk of gas leakage. The exhaust gas generated during the power generation process is treated and discharged, greatly reducing carbon emissions and meeting the requirements of low-carbon development.

  更實(shí)在的是,對(duì)山西煤礦來(lái)說(shuō),瓦斯發(fā)電機(jī)組就是“盈利神器”。不用額外花錢購(gòu)買燃料,“就地取材”用煤礦廢瓦斯發(fā)電,發(fā)出來(lái)的電既能滿足煤礦自身的用電需求,多余的還能并入電網(wǎng),獲得額外收益;而且像環(huán)能這樣的優(yōu)質(zhì)機(jī)型,故障率低、維護(hù)便捷,長(zhǎng)期運(yùn)行下來(lái),能為企業(yè)節(jié)省大量成本,真正實(shí)現(xiàn)“變害為寶、變廢為利”。

  More realistically, for Shanxi coal mines, gas generator sets are the "profit goddesses". There is no need to spend extra money to purchase fuel. Instead, coal mine waste gas is used locally to generate electricity. The generated electricity can meet the electricity needs of the coal mine itself, and the excess can be integrated into the power grid to obtain additional income; Moreover, high-quality models like Huaneng have low failure rates, easy maintenance, and long-term operation, which can save a lot of costs for enterprises and truly achieve the goal of "turning harm into treasure and waste into profit".

  如今的晉城,生態(tài)樣貌早已煥然一新,曾經(jīng)的“污染隱患”,變成了守護(hù)綠色家園的“清潔能源”,這一切的改變,離不開扎根實(shí)干的建設(shè)者,更離不開瓦斯發(fā)電機(jī)組的硬核支撐。從沁水寺河的60臺(tái)環(huán)能發(fā)電機(jī)組并網(wǎng),到蘆家峪的智慧電站落地,瓦斯發(fā)電機(jī)組見(jiàn)證了山西能源革命的每一步,也成為了煤礦綠色轉(zhuǎn)型的核心裝備。

  Nowadays, the ecological appearance of Jincheng has been completely transformed. The once "pollution hazard" has become a "clean energy" to protect the green home. All these changes cannot be separated from the builders who take root and work hard, and even more so from the hard core support of gas generators. From the grid connection of 60 circular energy generators in Qinshui Temple River to the landing of the smart power station in Lujiayu, gas generators have witnessed every step of Shanxi's energy revolution and have become the core equipment for coal mine green transformation.

  總結(jié)一下,山西瓦斯發(fā)電機(jī)組,尤其是環(huán)能機(jī)型,用實(shí)打?qū)嵉膶?shí)力,改寫了瓦斯的“命運(yùn)”,也推動(dòng)了山西能源革命的進(jìn)程。它不僅解決了煤礦瓦斯的安全、環(huán)保難題,還將廢瓦斯轉(zhuǎn)化為清潔電能,實(shí)現(xiàn)了安全、環(huán)保、盈利的三重收益,從荒山野嶺的艱難籌建,到智慧電站的蓬勃發(fā)展,每一臺(tái)瓦斯發(fā)電機(jī)組,都在訴說(shuō)著山西能源轉(zhuǎn)型的實(shí)干故事。

  To sum up, Shanxi gas power generation units, especially environmental energy models, have rewritten the "fate" of gas with practical strength and promoted the process of Shanxi's energy revolution. It not only solves the safety and environmental protection problems of coal mine gas, but also converts waste gas into clean electricity, achieving triple benefits of safety, environmental protection, and profitability. From the difficult construction of barren mountains and ridges to the vigorous development of smart power stations, every gas generator set is telling the practical story of Shanxi's energy transformation.

  對(duì)山西煤炭行業(yè)來(lái)說(shuō),瓦斯發(fā)電機(jī)組的普及,不是簡(jiǎn)單的技術(shù)升級(jí),更是發(fā)展模式的徹底轉(zhuǎn)變——它讓“一煤獨(dú)大”的山西,在煤炭開采的同時(shí),實(shí)現(xiàn)了清潔能源的高效利用,既守護(hù)了八百里太行山的綠水青山,又為國(guó)家能源安全助力,而這場(chǎng)由瓦斯發(fā)電機(jī)組引領(lǐng)的能源革命,還在繼續(xù)書寫著新的篇章。

  For the coal industry in Shanxi, the popularization of gas power generation units is not just a simple technological upgrade, but also a complete transformation of the development model. It enables Shanxi, which dominates coal mining, to achieve efficient utilization of clean energy while mining coal. It not only protects the green mountains and rivers of the 800 mile Taixing Mountains, but also contributes to national energy security. This energy revolution led by gas power generation units is still writing a new chapter.
