煤層氣在煤礦稱為煤礦瓦斯。依據新的資源評價成果,我國陸上煤層氣資源量36.8萬億立方米,與陸上慣例天然氣資源量(38萬億立方米)相當,僅次于俄羅斯和加拿大。煤層氣的主要成分是甲烷,甲烷在空氣中的濃度到達5%-16%時,遇明火就會爆炸,這是煤礦瓦斯爆炸事端的本源。 煤層氣不加以運用,直接排放到大氣中,其溫室效應約為二氧化碳的21倍。煤礦瓦斯發電,既可以有效地處理煤礦瓦斯事端、改善煤礦安全生產條件,又有利于增加潔凈能源供應、減少溫室氣體排放,到達保護生命、保護資源、保護環境的多重目標。

Coalbed methane is called coal mine gas in coal mine. According to the new resource evaluation results, China's onshore CBM resources amount to 36.8 trillion cubic meters, which is equivalent to the onshore conventional natural gas resources (38 trillion cubic meters), second only to Russia and Canada. The main component of coalbed methane is methane. When the concentration of methane reaches 5%-16% in the air, it will explode in open fire, which is the source of coal mine gas explosion. The greenhouse effect of coal bed methane (CBM) is about 21 times that of carbon dioxide (CO2) when it is discharged directly into the atmosphere without using it. Coal mine gas power generation can not only effectively deal with coal mine gas incidents, improve coal mine safety production conditions, but also help to increase the supply of clean energy, reduce greenhouse gas emissions, and achieve multiple objectives of protecting life, resources and environment.

D88尊龙煤礦瓦斯分高濃度瓦斯和低濃度瓦斯,高濃度瓦斯是指瓦斯濃度大于25%的瓦斯,低濃度瓦斯是指瓦斯濃度低于25%的瓦斯。我國60%以上的瓦斯是含甲烷25%以下的低濃度瓦斯,按煤礦安全規程要求,瓦斯濃度在25%以下的就不能貯存和運送,更談不上運用了。低濃度瓦斯發電需求處理2個問題,一是各個煤礦的自身不一樣,而且隨時都在改動,傳統的發電機組很難“以不變應萬變”;二是低濃度瓦斯的安全運送問題。低濃度瓦斯發電機組選用電控燃氣混合器技術,可以自動控制空燃比,以適應瓦斯的濃度改動,一起,低濃度瓦斯安全運送技術,選用細水霧技術,處理了低濃度瓦斯的地面安全運送問題。

Coal mine gas consists of high concentration gas and low concentration gas. High concentration gas refers to the gas whose concentration is more than 25%, and low concentration gas refers to the gas whose concentration is less than 25%. More than 60% of the gas in our country is low concentration gas containing less than 25% methane. According to the requirements of coal mine safety regulations, the gas concentration below 25% can not be stored and transported, let alone used. There are two problems to be dealt with in the demand of low concentration gas power generation. One is that each coal mine has its own difference and is changing at any time. It is difficult for traditional generating units to "respond to changes with unchangeability"; the other is the problem of safe transportation of low concentration gas. Electrically controlled gas mixer technology is used in low concentration gas generating units, which can automatically control air-fuel ratio to adapt to the change of gas concentration. Together, the technology of safe transportation of low concentration gas and water mist technology are used to deal with the problem of safe transportation of low concentration gas on the ground.

D88尊龙工程院周院士認為:“低濃度瓦斯發電機組,適合我國煤礦點多量小的特色,堪稱破解我國煤礦瓦斯難題的金鑰匙”。2004年以來,山東綠環動力開始對“煤礦瓦斯細水霧運送及發電技術”進行開發研討并與第二年試驗成功,使低濃度瓦斯發電技術得到了快速展開。現在裝機總容量到達43.5萬KW,每年可發電26.1億KW·H,運用瓦斯8.7億立方米。

Academician Zhou of the Chinese Academy of Engineering believes that "low concentration gas generating units are suitable for the characteristics of small quantity of coal mines in China, and can be regarded as the golden key to solve the gas problem in coal mines in China". Since 2004, Shandong Green Ring Power began to develop and discuss "Coal Mine Gas Water Mist Transport and Power Generation Technology" and succeeded in the second year's test, which enabled the low concentration gas power generation technology to be rapidly developed. Now the total installed capacity has reached 435,000 KW, generating 2.61 billion KW. H. per year and using 870 million cubic meters of gas.

D88尊龙、新版《煤礦安全規程》對濃度在30%以下的瓦斯用于內燃機發電作出了清晰的規矩,《規程》第148條第五項規矩:抽采的瓦斯濃度低于30%時,不得作為燃氣直接燃燒;用于內燃機發電或作其他用處時,瓦斯的運用、運送必須按有關標準的規矩,并擬定安全技術措施。這給低濃度瓦斯發電供應了原則確保。而我國煤礦60%以上的瓦斯是低濃度瓦斯,這是我國低濃度瓦斯發電的氣源確保。跟著低濃度瓦斯發電技術的不斷完善,低濃度煤層氣發電工業將會有良性的規模化展開,將會發作越來越大的經濟效益和社會效益。

The new edition of "Coal Mine Safety Regulations" clearly stipulates that the concentration of gas below 30% is used for internal combustion engine power generation. Article 148, Item 5 of the Regulations stipulates that when the concentration of gas extracted is below 30%, it shall not be used as direct combustion of gas; when used for internal combustion engine power generation or other uses, the application and transportation of gas must comply with the rules of relevant standards and formulate safety technical measures. Shi. This provides a principle guarantee for low concentration gas power generation. More than 60% of the gas in coal mines in China is low concentration gas, which is the gas source guarantee of low concentration gas power generation in China. With the continuous improvement of low-concentration gas power generation technology, the low-concentration coal-bed methane power generation industry will have a benign scale, and will have more and more economic and social benefits.
