重大突破！天池能源低濃度瓦斯發電機組并網投運，7.0%-20.0%瓦斯變廢為寶，年省300萬

　　Major breakthrough! Tianchi Energy's low concentration gas generator set is connected to the grid and put into operation, turning 7.0% -20.0% of gas waste into treasure, saving 3 million yuan annually

　　搞煤礦行業的老鐵們，一提瓦斯發電，大家可能都聽說過高濃度瓦斯發電，但很少有人知道，濃度在7.0%-20.0%的低濃度瓦斯，以前大多是“棄之可惜、用之無門”，既浪費能源，又有安全隱患。而最近，天池能源給行業打了個好樣——2月3日，天池金碳瓦斯發電廠并網啟動現場，隨著啟動鍵按下，中控大屏各項參數同步亮起，發電機組發出沉穩的運行聲，這標志著兗礦能源天池能源的低濃度瓦斯發電項目正式并網投運，也意味著瓦斯全濃度梯級利用終于實現了新突破！今天就結合這個項目，給大家嘮嘮瓦斯發電機組的干貨，說說低濃度瓦斯發電的門道，不用懂復雜術語，看完就能摸清其中的價值。

　　When it comes to gas power generation, all the old iron miners in the coal industry may have heard that the high concentration gas power generation, but few people know that the low concentration gas with the concentration of 7.0% -20.0% used to be "a pity to abandon it, and there is no way to use it", which is both a waste of energy and a potential safety hazard. Recently, Tianchi Energy has done a good job for the industry - on February 3rd, the Tianchi Gold Carbon Gas Power Plant was connected to the grid and started. With the start button pressed, various parameters on the central control screen synchronously lit up, and the generator set made a steady running sound. This marks the official grid connection and operation of Yankuang Energy's low concentration gas power generation project in Tianchi Energy, and also means that the full concentration cascade utilization of gas has finally achieved a new breakthrough! Today, in conjunction with this project, I will talk to you about the practical knowledge of gas power generation units, with a focus on the secrets of low concentration gas power generation. You don't need to understand complex terminology, and after reading it, you can understand its value.

　　先跟大家說句實在的，以前天池能源也有瓦斯發電項目，不過只和和順都寶電站合作，運營的是高濃度（＞20.0%）瓦斯發電廠，對于7.0%-20.0%的低濃度瓦斯，因為技術、安全等各方面原因，一直沒法充分利用，只能白白浪費，甚至還要花費人力物力處理，屬實可惜。而這次和晉中市金碳新能源公司合作，搭建的低濃度瓦斯發電機組，剛好補上了這個短板，踐行“應抽盡抽、應用盡用”的理念，真正實現了瓦斯全濃度梯級利用，這在行業內都是值得借鑒的。

　　To be honest with everyone, Tianchi Energy used to have gas power generation projects, but only cooperated with Heshun Dubao Power Station to operate high concentration (>20.0%) gas power plants. For low concentration gas of 7.0% -20.0%, due to technical, safety and other reasons, it has not been fully utilized and can only be wasted, even requiring manpower and material resources to deal with it. It is truly a pity. And the low concentration gas generator set built in cooperation with Jinzhong Jinchan New Energy Company this time has just filled this gap, practicing the concept of "should be exhausted and applied to the fullest", truly realizing the full concentration cascade utilization of gas, which is worth learning from in the industry.

　　可能有老鐵會問，低濃度瓦斯發電機組，和高濃度的有啥不一樣？核心其實還是瓦斯發電機組的適配性，低濃度瓦斯易燃易爆，濃度不穩定，對發電機組的安全防護、燃燒效率要求更高，而天池能源這個項目的發電機組，就專門針對低濃度瓦斯做了優化，既能穩定利用7.0%-20.0%的瓦斯，又能守住安全底線，這也是項目能成功并網的關鍵。

　　An old railway may ask, what is the difference between low concentration gas generator set and high concentration gas generator set? The core is actually the adaptability of the gas generator set. Low concentration gas is flammable and explosive, with unstable concentration, which requires higher safety protection and combustion efficiency for the generator set. The generator set of Tianchi Energy project has been optimized specifically for low concentration gas, which can stably utilize 7.0% -20.0% of gas while maintaining the safety bottom line. This is also the key to the successful grid connection of the project.

　　咱們先說說這個項目的核心配置，雙方共建了裝機容量3.5兆瓦的電廠，天池能源負責把井下抽采的低濃度瓦斯，通過專用管道輸送到電廠，每年能利用瓦斯730萬立方米，這些以前浪費的“閑置瓦斯”，現在都能通過發電機組，轉化為清潔電能，變廢為寶的同時，還能響應國家“雙碳”戰略。

　　Let's first talk about the core configuration of this project. Both parties have jointly built a power plant with an installed capacity of 3.5 megawatts. Tianchi Energy is responsible for transporting low concentration gas extracted underground to the power plant through dedicated pipelines, which can efficiently utilize 7.3 million cubic meters of gas annually. These previously wasted "idle gases" can now be converted into clean electricity through generator sets, turning waste into treasure while also responding to the national "dual carbon" strategy.

　　很多老鐵可能擔心，低濃度瓦斯燃燒發電，會不會有污染、不安全？完全不用擔心！瓦斯的主要成分是甲烷，不管是高濃度還是低濃度，只要通過瓦斯發電機組充分燃燒，排出的就只有水和二氧化碳，沒有粉塵、沒有有害氣體，是真正的清潔能源。而且這個項目的發電機組，配備了完善的安全防護系統，就像咱們之前說的，瓦斯易燃易爆，尤其是低濃度瓦斯，濃度波動大，所以發電機組和運輸管道上，都安裝了相應的安全保護裝置，確保運行安全，杜絕安全隱患。

　　Many old railways may worry about whether there will be pollution and insecurity when low concentration gas is burned for power generation? Don't worry at all! The main component of gas is methane. Whether it is high or low concentration, as long as it is fully burned by a gas generator, only water and carbon dioxide are discharged, without dust or harmful gases. It is a truly clean energy source. And the generator set of this project is equipped with a comprehensive safety protection system. As we mentioned before, gas is flammable and explosive, especially low concentration gas, which fluctuates greatly in concentration. Therefore, corresponding safety protection devices are installed on the generator set and transportation pipeline to ensure safe operation and eliminate safety hazards.

　　更讓人驚喜的是，這個項目的瓦斯發電機組，不僅能發電，還能實現“氣電熱補”多元化收益格局，性價比直接拉滿，這也是天池能源這個項目的一大亮點。咱們一步步說，首先是“電”的收益，電廠所發電量，會按低于國網平均電價的標準售予天池能源，僅瓦斯利用收益和電費節省兩項，預計每年就能給天池能源帶來約300萬元的直接經濟效益，這可是實實在在的收益。

　　What's even more surprising is that the gas generator set in this project can not only generate electricity, but also achieve a diversified profit pattern of "gas electricity heat supplement", with a high cost performance ratio. This is also a major highlight of the Tianchi Energy project. Step by step, the first benefit is the "electricity". The power plant's electricity generation will be sold to Tianchi Energy at a standard lower than the average electricity price of the State Grid. With only gas utilization benefits and electricity cost savings, it is expected to bring about 3 million yuan in direct economic benefits to Tianchi Energy every year, which is a real benefit.

　　其次是“熱”的利用，瓦斯發電機組在運行過程中，會產生一定的余熱，以前很多項目的余熱都是直接浪費，而天池能源這個項目，把發電機組產生的余熱，免費接入礦區供暖管路，一方面解決了原有熱源不足的問題，提升了礦區供暖質量，讓礦區職工冬天更暖和；另一方面也實現了能源梯級利用，大幅節約了供暖成本，相當于一臺發電機組，實現了“發電+供暖”雙重價值。

　　Secondly, the utilization of "heat". During the operation of gas generators, a certain amount of waste heat is generated. In the past, the waste heat of many projects was directly wasted. However, in the Tianchi Energy project, the waste heat generated by the generator set is connected to the heating pipeline in the mining area for free. On the one hand, it solves the problem of insufficient heat sources, improves the quality of heating in the mining area, and makes winter warmer for mining workers; On the other hand, it has also achieved energy cascade utilization, greatly saving heating costs, equivalent to a generator set, realizing the dual value of "power generation+heating".

　　這里給大家補充個小知識點，瓦斯發電機組的核心價值，從來都不只是發電，更重要的是“以用促抽、以抽保安”的良性循環。以前井下低濃度瓦斯堆積，抽采后沒法利用，只能排放，既浪費又有安全隱患；而有了低濃度瓦斯發電機組，就能持續抽采井下瓦斯，降低井下瓦斯濃度，從源頭減少瓦斯爆炸的風險，改善煤礦安全生產條件，這也是天池能源大力推進這個項目的重要原因。

　　Here is a small knowledge point to supplement for everyone. The core value of gas generator sets is never just about power generation, but more importantly, the virtuous cycle of "using to promote extraction and using extraction to ensure safety". Previously, low concentration gas accumulation underground could not be utilized after extraction, and could only be discharged, which was both wasteful and had safety hazards; With the low concentration gas generator set, it is possible to continuously extract underground gas, reduce the concentration of underground gas, reduce the risk of gas explosion from the source, and improve the safety production conditions of coal mines. This is also an important reason why Tianchi Energy vigorously promotes this project.

　　而且這個項目還有一個重大意義，作為響應國家“雙碳”戰略的務實舉措，它每年可減排二氧化碳約10.8萬噸，相當于給環境“減負”，同時也為行業低濃度瓦斯綜合利用，提供了可復制、可推廣的“天池樣板”，以后其他煤礦有類似的低濃度瓦斯資源，都能參考這個模式，實現瓦斯全濃度利用。

　　And this project also has a significant meaning. As a practical measure in response to the national "dual carbon" strategy, it can reduce carbon dioxide emissions by about 108000 tons per year, which is equivalent to "reducing the burden" on the environment. At the same time, it also provides a replicable and scalable "Tianchi model" for the comprehensive utilization of low concentration gas in the industry. In the future, other coal mines with similar low concentration gas resources can refer to this model to achieve full concentration utilization of gas.

　　很多老鐵可能會覺得，瓦斯發電機組聽起來復雜，其實整個運行過程都是自動化、智能化的，就像天池金碳瓦斯發電廠這樣，啟動后中控大屏實時監測各項參數，發電機組沉穩運行，不用人工全程值守，既省心又。而且這種“自發自用、余電上網”的合作運營模式，也很靈活，既能保障天池能源自身的用電需求，又能實現能源的優化配置，提升能源價值。

　　Many old railways may think that the gas generator set sounds complicated, but in fact the whole operation process is automated and intelligent, just like Tianchi Gold Carbon Gas Power Plant. After startup, the central control large screen monitors various parameters in real time, and the generator set operates steadily without full manual watch, which is both worry free and efficient. Moreover, this cooperative operation model of "spontaneous self use and surplus electricity grid connection" is also very flexible, which can not only ensure the electricity demand of Tianchi Energy itself, but also achieve optimized energy allocation and enhance energy value.

　　總結一下，天池能源這次投運的低濃度瓦斯發電機組，不僅破解了7.0%-20.0%低濃度瓦斯無法充分利用的難題，實現了瓦斯全濃度梯級利用的新突破，更通過“氣電熱補”的多元化模式，實現了環保、安全、效益三者兼顧。它用實際案例證明，不管是高濃度還是低濃度瓦斯，只要選對瓦斯發電機組，做好梯級利用，就能把“危險氣體”變成“效益源泉”。

　　To sum up, the low concentration gas generator set put into operation by Tianchi Energy not only solves the problem of insufficient utilization of 7.0% -20.0% low concentration gas and achieves a new breakthrough in the cascade utilization of full concentration gas, but also achieves a balance between environmental protection, safety, and efficiency through the diversified mode of "gas electric heating". It has proven through practical cases that whether it is high concentration or low concentration gas, as long as the gas generator set is selected correctly and the cascade utilization is done well, the "hazardous gas" can be turned into a "source of benefits".

　　相信未來，隨著技術的不斷升級，瓦斯發電機組會越來越普及，越來越多的煤礦會借鑒天池能源的模式，實現瓦斯全濃度利用，既響應國家“雙碳”戰略，又能改善安全生產條件、增加企業收益，走出一條綠色、安全、的能源利用新路徑。

　　Believing in the future, with the continuous upgrading of technology, gas generator sets will become increasingly popular, and more and more coal mines will learn from the model of Tianchi Energy to achieve full concentration utilization of gas. This not only responds to the national "dual carbon" strategy, but also improves safety production conditions, increases enterprise profits, and opens up a new path of green, safe, and efficient energy utilization.
