　　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

　　搞煤矿行业的老铁们，一提瓦斯发电，大家可能都听说过高浓度瓦斯发电，但很少有人知道，浓度在7.0%-20.0%的低浓度瓦斯，以前大多是“弃之可惜、用之无门”，既浪费能源，又有安全隐患。而最近，天池能源给行业打了个好样——2月3日，天池金碳瓦斯发电厂并网启动现场，随着启动键按下，中控大屏各项参数同步亮起，发电机组发出沉稳的运行声，这标志着兖矿能源天池能源的低浓度瓦斯发电项目正式并网投运，也意味着瓦斯全浓度梯级利用终于实现了新突破！今天就结合这个项目，给大家唠唠瓦斯发电机组的干货，重点说说低浓度瓦斯发电的门道，不用懂复杂术语，看完就能摸清其中的价值。

　　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.

　　先跟大家说句实在的，以前天池能源也有瓦斯发电项目，不过只和和顺都宝电站合作，运营的是高浓度（＞20.0%）瓦斯发电厂，对于7.0%-20.0%的低浓度瓦斯，因为技术、安全等各方面原因，一直没法充分利用，只能白白浪费，甚至还要花费人力物力处理，属实可惜。而这次和晋中市金碳新能源公司合作，搭建的低浓度瓦斯发电机组，刚好补上了这个短板，践行“应抽尽抽、应用尽用”的理念，真正实现了瓦斯全浓度梯级利用，这在行业内都是值得借鉴的。

　　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.

　　可能有老铁会问，低浓度瓦斯发电机组，和高浓度的有啥不一样？核心其实还是瓦斯发电机组的适配性，低浓度瓦斯易燃易爆，浓度不稳定，对发电机组的安全防护、燃烧效率要求更高，而天池能源这个项目的发电机组，就专门针对低浓度瓦斯做了优化，既能稳定利用7.0%-20.0%的瓦斯，又能守住安全底线，这也是项目能成功并网的关键。

　　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.

　　咱们先说说这个项目的核心配置，双方共建了装机容量3.5兆瓦的电厂，天池能源负责把井下抽采的低浓度瓦斯，通过专用管道输送到电厂，每年能高效利用瓦斯730万立方米，这些以前浪费的“闲置瓦斯”，现在都能通过发电机组，转化为清洁电能，变废为宝的同时，还能响应国家“双碳”战略。

　　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.

　　很多老铁可能担心，低浓度瓦斯燃烧发电，会不会有污染、不安全？完全不用担心！瓦斯的主要成分是甲烷，不管是高浓度还是低浓度，只要通过瓦斯发电机组充分燃烧，排出的就只有水和二氧化碳，没有粉尘、没有有害气体，是真正的清洁能源。而且这个项目的发电机组，配备了完善的安全防护系统，就像咱们之前说的，瓦斯易燃易爆，尤其是低浓度瓦斯，浓度波动大，所以发电机组和运输管道上，都安装了相应的安全保护装置，确保运行安全，杜绝安全隐患。

　　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.

　　更让人惊喜的是，这个项目的瓦斯发电机组，不仅能发电，还能实现“气电热补”多元化收益格局，性价比直接拉满，这也是天池能源这个项目的一大亮点。咱们一步步说，首先是“电”的收益，电厂所发电量，会按低于国网平均电价的标准售予天池能源，仅瓦斯利用收益和电费节省两项，预计每年就能给天池能源带来约300万元的直接经济效益，这可是实实在在的收益。

　　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“热”的利用，瓦斯发电机组在运行过程中，会产生一定的余热，以前很多项目的余热都是直接浪费，而天池能源这个项目，把发电机组产生的余热，免费接入矿区供暖管路，一方面解决了原有热源不足的问题，提升了矿区供暖质量，让矿区职工冬天更暖和；另一方面也实现了能源梯级利用，大幅节约了供暖成本，相当于一台发电机组，实现了“发电+供暖”双重价值。

　　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".

　　这里给大家补充个小知识点，瓦斯发电机组的核心价值，从来都不只是发电，更重要的是“以用促抽、以抽保安”的良性循环。以前井下低浓度瓦斯堆积，抽采后没法利用，只能排放，既浪费又有安全隐患；而有了低浓度瓦斯发电机组，就能持续抽采井下瓦斯，降低井下瓦斯浓度，从源头减少瓦斯爆炸的风险，改善煤矿安全生产条件，这也是天池能源大力推进这个项目的重要原因。

　　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.

　　而且这个项目还有一个重大意义，作为响应国家“双碳”战略的务实举措，它每年可减排二氧化碳约10.8万吨，相当于给环境“减负”，同时也为行业低浓度瓦斯综合利用，提供了可复制、可推广的“天池样板”，以后其他煤矿有类似的低浓度瓦斯资源，都能参考这个模式，实现瓦斯全浓度利用。

　　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.

　　很多老铁可能会觉得，瓦斯发电机组听起来复杂，其实整个运行过程都是自动化、智能化的，就像天池金碳瓦斯发电厂这样，启动后中控大屏实时监测各项参数，发电机组沉稳运行，不用人工全程值守，既省心又高效。而且这种“自发自用、余电上网”的合作运营模式，也很灵活，既能保障天池能源自身的用电需求，又能实现能源的优化配置，提升能源价值。

　　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.

　　总结一下，天池能源这次投运的低浓度瓦斯发电机组，不仅破解了7.0%-20.0%低浓度瓦斯无法充分利用的难题，实现了瓦斯全浓度梯级利用的新突破，更通过“气电热补”的多元化模式，实现了环保、安全、效益三者兼顾。它用实际案例证明，不管是高浓度还是低浓度瓦斯，只要选对瓦斯发电机组，做好梯级利用，就能把“危险气体”变成“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".

　　相信未来，随着技术的不断升级，瓦斯发电机组会越来越普及，越来越多的煤矿会借鉴天池能源的模式，实现瓦斯全浓度利用，既响应国家“双碳”战略，又能改善安全生产条件、增加企业收益，走出一条绿色、安全、高效的能源利用新路径。

　　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.
