瓦斯，煤礦安全生產(chǎn)的“頭號(hào)殺手”，同時(shí)也是溫室效應(yīng)約為二氧化碳21倍的強(qiáng)效溫室氣體。瓦斯發(fā)電機(jī)組所扮演的角色，正是將這種潛伏在礦井下的危險(xiǎn)氣體，馴服為清潔電力的“安全衛(wèi)士”。它不僅為煤礦提供了一條本質(zhì)安全的瓦斯治理路徑，更將“風(fēng)險(xiǎn)源”變成了“能源礦”。

Gas, the "number one killer" of coal mine safety production, is also a potent greenhouse gas with a greenhouse effect about 21 times that of carbon dioxide. The role played by gas generators is to tame this dangerous gas lurking underground into a "safety guard" for clean electricity. It not only provides an inherently safe gas control path for coal mines, but also turns the "risk source" into an "energy mine".

一、使用范圍：覆蓋高中低濃度瓦斯

1、 Scope of use: Covering high, medium, and low concentration gases

瓦斯發(fā)電機(jī)組專為煤礦瓦斯（煤層氣） 開(kāi)發(fā)利用而設(shè)計(jì)，覆蓋了從高濃度到低濃度的廣闊區(qū)間。

The gas generator set is designed specifically for the development and utilization of coal mine gas (coalbed methane), covering a wide range from high concentration to low concentration.

高濃度瓦斯（甲烷>25%）：可直接通過(guò)常規(guī)瓦斯發(fā)電機(jī)組進(jìn)行穩(wěn)定發(fā)電，技術(shù)成熟，單機(jī)功率可達(dá)1500千瓦以上。

High concentration gas (methane>25%): Stable power generation can be achieved directly through conventional gas generators, with mature technology and a single unit power of over 1500 kilowatts.

低濃度瓦斯（甲烷6%-25%）：這是我國(guó)60%以上瓦斯的賦存形態(tài)，也是技術(shù)攻關(guān)的重點(diǎn)?，F(xiàn)代機(jī)組通過(guò)細(xì)水霧安全輸送技術(shù)和電控燃?xì)饣旌掀?，解決了低濃度瓦斯地面安全輸送和濃度自適應(yīng)難題，可將瓦斯?jié)舛冗m應(yīng)范圍拓展至8%-40%。

Low concentration gas (methane 6% -25%): This is the occurrence form of over 60% of gas in China and also a key focus of technological research and development. Modern units have solved the problem of safe ground transportation and concentration adaptation of low concentration gas through fine water mist safety transportation technology and electrically controlled gas mixers, and can expand the gas concentration adaptation range to 8% -40%.

二、核心優(yōu)勢(shì)：安全、環(huán)保與高效的三重奏

2、 Core advantage: a trio of safety, environmental protection, and efficiency

瓦斯發(fā)電機(jī)組的技術(shù)價(jià)值遠(yuǎn)超單純的能源產(chǎn)出。

The technical value of gas power generation units far exceeds simple energy output.

主動(dòng)治理，提升安全水平：通過(guò)抽采利用瓦斯，從根本上降低了井下瓦斯?jié)舛?，減少了爆炸風(fēng)險(xiǎn)。這是“先抽后采、以用促抽”政策的落地工具。

Proactive governance and improvement of safety level: By extracting and utilizing gas, the underground gas concentration has been fundamentally reduced, reducing the risk of explosion. This is the implementation tool of the policy of 'draw first, collect later, use to promote draw'.

適應(yīng)氣源波動(dòng)，穩(wěn)定輸出：煤礦瓦斯抽采濃度隨地質(zhì)條件和抽采時(shí)間不斷變化。機(jī)組采用空燃比閉環(huán)控制和稀薄燃燒技術(shù)，能實(shí)時(shí)感知濃度變化并自動(dòng)調(diào)整燃燒參數(shù)，即便在濃度從8%到40%的寬幅波動(dòng)中，仍能保證功率穩(wěn)定輸出。

Adapt to gas source fluctuations and maintain stable output: The concentration of coal mine gas extraction constantly changes with geological conditions and extraction time. The unit adopts air-fuel ratio closed-loop control and lean combustion technology, which can sense concentration changes in real time and automatically adjust combustion parameters. Even in the wide range of concentration fluctuations from 8% to 40%, it can still ensure stable power output.

高效低排，綠色發(fā)電：先進(jìn)機(jī)型的熱耗率可低至9000 kJ/kW·h，氮氧化物排放可控制在469-500 mg/Nm?以下。同時(shí)，機(jī)組支持多臺(tái)并聯(lián)建站，既可滿足礦井自用電，也可并入國(guó)家電網(wǎng)，將減排的碳指標(biāo)轉(zhuǎn)化為經(jīng)濟(jì)收益。

Efficient and low emission, green power generation: The heat consumption rate of advanced models can be as low as 9000 kJ/kW · h, and nitrogen oxide emissions can be controlled between 469-500 mg/Nm? following. At the same time, the unit supports the construction of multiple parallel stations, which can meet the self use electricity of the mine or be integrated into the national power grid, converting the carbon reduction targets into economic benefits.
