　　Unveiling the Gas Generator Unit of Yongmei Main Coking Coal Mine! Methane to electricity conversion, four major systems+full safety protection, new path of clean energy

　　搞煤礦行業(yè)的老鐵們，一提礦井瓦斯，很多人第一反應(yīng)就是“安全隱患”“定時(shí)炸彈”，但很少有人知道，瓦斯其實(shí)是藏在井下的“寶藏清潔能源”！它的主要成分是甲烷，經(jīng)過(guò)充分燃燒利用，只會(huì)排出水和二氧化碳，沒(méi)有多余污染，既能變廢為寶，還能改善煤礦安全生產(chǎn)條件。今天咱們就走進(jìn)永煤集團(tuán)主焦煤礦風(fēng)景工區(qū)，實(shí)地看看瓦斯發(fā)電機(jī)組是如何工作的，把它的發(fā)電原理、核心系統(tǒng)、安全保障一次性說(shuō)透，不用懂復(fù)雜術(shù)語(yǔ)，看完就能摸清瓦斯發(fā)電的門(mén)道，領(lǐng)略不一樣的煤礦科普干貨。

　　As for the old iron miners in the coal mining industry, when they mention the mine gas, many people first respond to the "hidden danger" and "time bomb", but few people know that the gas is actually the "treasure clean energy" hidden underground! Its main component is methane, which, after full combustion and utilization, only emits water and carbon dioxide without excess pollution. It can turn waste into treasure and improve coal mine safety production conditions. Today we will enter the scenic work area of Yongmei Group's main coking coal mine to see how the gas generator unit works on site. We will explain its power generation principle, core system, and safety guarantee in one go. Without understanding complex terminology, we can understand the way of gas power generation and appreciate different coal mine science popularization knowledge.

　　先跟大家說(shuō)句實(shí)在的，以前礦井瓦斯大多是直接排放，既浪費(fèi)了寶貴的能源，又給煤礦生產(chǎn)帶來(lái)了極大的安全隱患——甲烷易燃易爆，濃度超標(biāo)就可能引發(fā)危險(xiǎn)。而現(xiàn)在，有了瓦斯發(fā)電機(jī)組，咱們就能把這“危險(xiǎn)氣體”變成“綠色電能”，永煤集團(tuán)就做得很到位，旗下主焦煤礦等礦井升級(jí)高效發(fā)電機(jī)組后，發(fā)電效率大幅提升，既解決了瓦斯安全隱患，又實(shí)現(xiàn)了增收增效，一舉兩得。

　　To be honest with everyone, in the past, most mine gas was directly discharged, which not only wasted valuable energy but also brought great safety hazards to coal mine production - methane is flammable and explosive, and excessive concentration may cause danger. Now, with gas generator sets, we can turn this "dangerous gas" into "green electricity". Yongmei Group has done a great job. After upgrading high-efficiency generator sets in its main coking coal mines and other mines, the power generation efficiency has been greatly improved, which not only solves gas safety hazards but also achieves increased income and efficiency, killing two birds with one stone.

　　其實(shí)瓦斯發(fā)電并不復(fù)雜，核心就是靠瓦斯發(fā)電機(jī)組，整個(gè)發(fā)電過(guò)程主要由四大系統(tǒng)協(xié)同配合，缺一不可，咱們結(jié)合永煤主焦煤礦的實(shí)操場(chǎng)景，一步步給大家嘮。

　　In fact, gas power generation is not complicated. The core relies on gas generator sets. The entire power generation process is mainly coordinated by four major systems, and none of them are indispensable. Combining with the practical scenarios of Yongmei main coking coal mine, we will explain step by step.

　　第一個(gè)系統(tǒng)，也是發(fā)電的“源頭保障”——瓦斯運(yùn)輸系統(tǒng)。礦井里的瓦斯藏在井下深處，首先得靠進(jìn)水環(huán)真空泵把它從井下抽出來(lái)，就像“抽氣泵”一樣，穩(wěn)穩(wěn)把瓦斯抽至地面，再通過(guò)專用瓦斯管道，一步步輸送到瓦斯發(fā)電機(jī)組，全程密閉運(yùn)輸，避免瓦斯泄漏。

　　The first system, which is also the "source guarantee" for power generation, is the gas transportation system. The gas in the mine is hidden deep underground. First, it needs to be pumped out of the mine by a water inlet ring vacuum pump, just like a "vacuum pump", to steadily pump the gas to the surface. Then, it is transported step by step to the gas generator set through a dedicated gas pipeline, and transported in a closed manner throughout the entire process to avoid gas leakage.

　　這里重點(diǎn)說(shuō)下安全防護(hù)，瓦斯易燃易爆，運(yùn)輸過(guò)程中半點(diǎn)馬虎不得！永煤主焦煤礦的瓦斯運(yùn)輸系統(tǒng)里，專門(mén)安裝了一整套安全保護(hù)裝置，有水風(fēng)阻火泄爆裝置、干式阻火器、濕式放散閥，還有絲網(wǎng)過(guò)濾器，每一個(gè)都有大作用：阻火器和泄爆裝置能防止瓦斯燃燒回火、發(fā)生爆炸，濕式放散閥能在瓦斯?jié)舛瘸瑯?biāo)時(shí)，自動(dòng)放散多余瓦斯，絲網(wǎng)過(guò)濾器則能過(guò)濾掉瓦斯中的雜質(zhì)，保護(hù)后續(xù)發(fā)電機(jī)組不受損壞，全方位守住安全底線。

　　The key point here is safety protection. Gas is flammable and explosive, and no carelessness is allowed during transportation! In the gas transportation system of Yongmei Main Coking Coal Mine, a complete set of safety protection devices has been specially installed, including water air flame arrester and explosion relief device, dry flame arrester, wet release valve, and wire mesh filter, each of which has a great role: flame arrester and explosion relief device can prevent gas combustion and explosion, wet release valve can automatically release excess gas when the gas concentration exceeds the standard, and wire mesh filter can filter out impurities in the gas, protect subsequent generator sets from damage, and comprehensively safeguard the safety bottom line.

　　第二個(gè)系統(tǒng)，也是整個(gè)發(fā)電過(guò)程的“核心心臟”——瓦斯發(fā)電機(jī)組系統(tǒng)。經(jīng)過(guò)運(yùn)輸和安全處理后的瓦斯，會(huì)被輸送到這個(gè)系統(tǒng)的發(fā)動(dòng)機(jī)內(nèi)，充分燃燒做功，就像咱們家里的燃?xì)庠钊紵烊粴猱a(chǎn)生熱量一樣，瓦斯燃燒產(chǎn)生的能量，會(huì)帶動(dòng)發(fā)電機(jī)組運(yùn)轉(zhuǎn)，進(jìn)而將熱能轉(zhuǎn)化為電能，這一步就是瓦斯變電能的關(guān)鍵，永煤集團(tuán)升級(jí)高效發(fā)電機(jī)組后，發(fā)電效率已提升至63%以上，效益十分可觀。

　　The second system, also the "core heart" of the entire power generation process - the gas generator system. After transportation and safety treatment, the gas will be transported to the engine of this system and fully burned to do work, just like the gas stove in our home burns natural gas to generate heat. The energy generated by gas combustion will drive the generator set to operate, and then convert the heat energy into electrical energy. This step is the key to gas to electricity conversion. After upgrading the high-efficiency generator set, Yongmei Group has increased the power generation efficiency to over 63%, and the benefits are very considerable.

　　可能有老鐵會(huì)問(wèn)，瓦斯燃燒會(huì)不會(huì)有污染？完全不用擔(dān)心！前面咱們已經(jīng)說(shuō)過(guò)，瓦斯的主要成分是甲烷，只要充分燃燒，排出的就只有水和二氧化碳，沒(méi)有粉塵、沒(méi)有有害氣體，是真正的清潔能源，這也是瓦斯發(fā)電最突出的優(yōu)勢(shì)之一，既利用了廢棄資源，又契合綠色環(huán)保的大趨勢(shì)。

　　Maybe some old iron would ask, will gas burning pollute? Don't worry at all! As we mentioned earlier, the main component of gas is methane. As long as it is fully burned, only water and carbon dioxide are emitted, without dust or harmful gases. It is a truly clean energy source, and this is also one of the most prominent advantages of gas power generation. It not only utilizes waste resources, but also conforms to the trend of green environmental protection.

　　第三個(gè)系統(tǒng)，負(fù)責(zé)“輸送電能”——并網(wǎng)供電系統(tǒng)。發(fā)電機(jī)組產(chǎn)生電能后，并不是直接就能用，還需要經(jīng)過(guò)處理，達(dá)到供電標(biāo)準(zhǔn)后，再并入煤礦的變電所，一方面可以滿足煤礦自身的生產(chǎn)、生活用電需求，比如井下設(shè)備運(yùn)轉(zhuǎn)、礦區(qū)照明等，降低對(duì)外部電網(wǎng)的依賴；另一方面，多余的電能還能并網(wǎng)銷(xiāo)售，給企業(yè)增加額外收益，永煤集團(tuán)旗下礦井僅1至9月份，就靠瓦斯發(fā)電節(jié)約用電成本超2000萬(wàn)元。

　　The third system is responsible for "transmitting electrical energy" - grid connected power supply system. After the generator set generates electricity, it cannot be used directly. It needs to be processed to meet the power supply standards before being integrated into the coal mine substation. On the one hand, it can meet the production and living electricity needs of the coal mine itself, such as the operation of underground equipment and lighting in the mining area, reducing dependence on the external power grid; On the other hand, excess electricity can also be connected to the grid for sale, adding extra revenue to the enterprise. From January to September, mines under Yongmei Group saved over 20 million yuan in electricity costs by relying on gas power generation.

　　第四個(gè)系統(tǒng)，實(shí)現(xiàn)“余熱再利用”——余熱利用系統(tǒng)（咱們重點(diǎn)說(shuō)下它的價(jià)值）。瓦斯在發(fā)動(dòng)機(jī)內(nèi)燃燒做功時(shí)，會(huì)產(chǎn)生一定的余熱，以前這些余熱大多是直接浪費(fèi)掉，而現(xiàn)在通過(guò)余熱利用系統(tǒng)，能把這些余熱回收起來(lái)，用于礦區(qū)供暖、熱水供應(yīng)等，進(jìn)一步提高能源利用率，做到“一物兩用”，既節(jié)能又環(huán)保，最大化發(fā)揮瓦斯的價(jià)值。

　　The fourth system is to achieve "waste heat reuse" - waste heat utilization system (let's focus on its value). When gas burns and does work in the engine, it generates a certain amount of waste heat. In the past, most of this waste heat was directly wasted, but now through waste heat utilization systems, this waste heat can be recovered and used for heating and hot water supply in mining areas, further improving energy utilization efficiency and achieving "dual-use", which is both energy-saving and environmentally friendly, maximizing the value of gas.

　　這里給大家補(bǔ)充個(gè)小知識(shí)點(diǎn)，瓦斯發(fā)電機(jī)組的核心優(yōu)勢(shì)，不僅是變廢為寶、綠色環(huán)保，更重要的是能改善煤礦安全生產(chǎn)條件。以前井下瓦斯堆積，需要花費(fèi)大量人力、物力進(jìn)行抽排，而瓦斯發(fā)電機(jī)組的投入使用，能持續(xù)抽采井下瓦斯，降低井下瓦斯?jié)舛龋瑥脑搭^減少瓦斯爆炸的安全隱患，讓煤礦生產(chǎn)更安全、更穩(wěn)定，這也是永煤集團(tuán)大力推廣瓦斯發(fā)電項(xiàng)目的重要原因。

　　Here is a small knowledge point to supplement for everyone. The core advantage of gas generator sets is not only to turn waste into treasure and promote green environmental protection, but more importantly, to improve the safety production conditions of coal mines. Previously, the accumulation of underground gas required a large amount of manpower and material resources for drainage. However, the use of gas generator sets can continuously extract underground gas, reduce the concentration of underground gas, and reduce the safety hazards of gas explosions from the source, making coal mining production safer and more stable. This is also an important reason why Yongmei Group vigorously promotes gas power generation projects.

　　很多老鐵可能會(huì)覺(jué)得，瓦斯發(fā)電聽(tīng)起來(lái)復(fù)雜，其實(shí)整個(gè)過(guò)程都是自動(dòng)化、智能化運(yùn)行，有專門(mén)的控制系統(tǒng)實(shí)時(shí)監(jiān)測(cè)各個(gè)系統(tǒng)的運(yùn)行狀態(tài)，比如瓦斯?jié)舛取l(fā)電機(jī)組轉(zhuǎn)速、電壓等，一旦出現(xiàn)異常，會(huì)自動(dòng)報(bào)警、及時(shí)處理，不用人工全程值守，既省心又安全。

　　Many old railways may think that gas power generation sounds complicated, but in fact, the whole process is automatic and intelligent. There is a special control system to monitor the operation status of each system in real time, such as gas concentration, generator speed, voltage, etc. In case of any abnormality, it will automatically alarm and deal with it in a timely manner, without having to be on duty all the time manually, which is both worry free and safe.

　　總結(jié)一下，瓦斯發(fā)電機(jī)組，就是把礦井里的“危險(xiǎn)瓦斯”，通過(guò)“瓦斯運(yùn)輸—燃燒做功—并網(wǎng)供電—余熱利用”四大系統(tǒng)，轉(zhuǎn)化為“綠色電能”的核心設(shè)備，它不僅能讓甲烷這種清潔能源得到充分利用，減少環(huán)境污染，還能改善煤礦安全生產(chǎn)條件、增加企業(yè)收益，一舉多得。

　　To sum up, the gas generator set is the core equipment that converts the "dangerous gas" in the mine into "green electricity" through the four major systems of "gas transportation - combustion work - grid connected power supply - waste heat utilization". It not only fully utilizes methane, a clean energy source, to reduce environmental pollution, but also improves coal mine safety production conditions and increases enterprise profits, achieving multiple benefits in one fell swoop.

　　就像永煤集團(tuán)主焦煤礦這樣，通過(guò)合理利用瓦斯發(fā)電機(jī)組，既解決了瓦斯安全隱患，又實(shí)現(xiàn)了清潔能源供應(yīng)和增收增效，走出了一條綠色、安全、高效的能源利用新路徑。相信未來(lái)，隨著技術(shù)的不斷升級(jí)，瓦斯發(fā)電機(jī)組會(huì)越來(lái)越普及，讓更多礦井的“危險(xiǎn)氣體”，變成守護(hù)安全、創(chuàng)造價(jià)值的“綠色電能”。

　　Just like the main coking coal mine of Yongmei Group, through the rational use of gas generator sets, not only have gas safety hazards been solved, but also clean energy supply and increased income and efficiency have been achieved, paving a new path for green, safe, and efficient energy utilization. Believe in the future, with the continuous upgrading of technology, gas generator sets will become more and more popular, turning more "dangerous gases" in mines into "green electricity" that safeguards safety and creates value.
