Coal mine gas is divided into high concentration gas and low concentration gas. High concentration gas refers to gas with a gas concentration greater than 30%, while low concentration gas refers to gas with a gas concentration lower than 30%. More than 60% of the gas in China contains A

烷30%以下的低濃度瓦斯，按煤礦安全規(guī)程要求，瓦斯?jié)舛仍?0%以下的就不能貯存和輸送，更談不上利用了。

Low concentration gas with an alkane content below 30% cannot be stored and transported, let alone utilized, according to coal mine safety regulations.

低濃度瓦斯發(fā)電需要解決2個問題，一是各個煤礦的本身不一樣，而且隨時都在變化，傳統(tǒng)的發(fā)電機組很難“以不變應(yīng)萬變”;二是低濃度瓦斯的安全輸

Low concentration gas power generation needs to solve two problems: firstly, each coal mine itself is different and constantly changing, making it difficult for traditional power generation units to "adapt to changes with immutability"; The second is the safe transportation of low concentration gas

送問題.濟柴低濃度瓦斯發(fā)電機組采用電控燃氣混合器技術(shù)，可以自動控制空燃比，以適應(yīng)瓦斯的濃度變化，同時，低濃度瓦斯安全輸送技術(shù)，采用細水霧及多重阻火技術(shù)，解決了低濃度瓦斯的地面安全輸送問題。

Delivery issues. The Jichai low concentration gas generator unit adopts electronic control gas mixer technology, which can automatically control the air fuel ratio to adapt to changes in gas concentration. At the same time, the low concentration gas safety transportation technology adopts fine water mist and multiple fire resistance technologies, solving the problem of ground safety transportation of low concentration gas.

瓦斯用于內(nèi)燃機發(fā)電作出了抽采的瓦斯?jié)舛鹊陀?0%時，不得作為燃氣直接燃燒;用于內(nèi)燃機發(fā)電或作其他用途時，瓦斯的利用、輸送必須按

When gas is used for internal combustion engine power generation and the concentration of extracted gas is less than 30%, it shall not be directly burned as gas; When used for internal combustion engine power generation or other purposes, the utilization and transportation of gas must comply with

有關(guān)標準的規(guī)定，并制定安全技術(shù)措施。這給低濃度瓦斯發(fā)電提供了制度保障。

Provisions on relevant standards and development of safety technical measures. This provides institutional guarantees for low concentration gas power generation.
