  14臺(tái)滿(mǎn)負(fù)荷發(fā)力!濟(jì)柴沼氣發(fā)電機(jī)組,解鎖煤礦瓦斯發(fā)電新標(biāo)桿

  14 units at full capacity! Jichai biogas generator set unlocks a new benchmark for coal mine gas power generation

  在煤礦行業(yè),瓦斯既是安全隱患,也是可回收利用的清潔能源——低濃度瓦斯若直接排放,既浪費(fèi)能源又污染環(huán)境,而沼氣發(fā)電機(jī)組的出現(xiàn),實(shí)現(xiàn)了“變險(xiǎn)為寶”。其中,貴州省大西南宜興煤礦瓦斯發(fā)電站的實(shí)踐極具代表性,14臺(tái)濟(jì)柴沼氣發(fā)電機(jī)組成功并網(wǎng)發(fā)電,總裝機(jī)容量達(dá)14兆瓦,截至目前累計(jì)發(fā)電量突破300萬(wàn)度,用實(shí)打?qū)嵉臄?shù)據(jù)印證了濟(jì)柴機(jī)組的硬核實(shí)力,今天就跟大伙嘮透這款煤礦瓦斯發(fā)電的“王牌裝備”。

  In the coal mining industry, gas is not only a safety hazard, but also a recyclable clean energy source - if low concentration gas is directly discharged, it will not only waste energy but also pollute the environment. The emergence of biogas generators has realized the "turning danger into treasure". Among them, the practice of Yixing Coal Mine Gas Power Station in southwestern Guizhou Province is highly representative. 14 Jichai biogas generator units have been successfully connected to the grid for power generation, with a total installed capacity of 14 megawatts. As of now, the cumulative power generation has exceeded 3 million kilowatt hours, which confirms the hard core strength of Jichai units with real data. Today, we will talk about this "ace equipment" for coal mine gas power generation.

  作為深耕氣體發(fā)電領(lǐng)域百年的老牌國(guó)企,濟(jì)柴打造的沼氣發(fā)電機(jī)組,專(zhuān)門(mén)適配煤礦低濃度瓦斯場(chǎng)景,此次宜興煤礦選用的機(jī)型,單機(jī)額定功率達(dá)1兆瓦,實(shí)際滿(mǎn)負(fù)荷運(yùn)行時(shí)功率穩(wěn)定在950-1000千瓦,14臺(tái)機(jī)組同步發(fā)力,可實(shí)現(xiàn)全天候滿(mǎn)負(fù)荷運(yùn)轉(zhuǎn),完全適配煤礦規(guī)?;咚固幚砼c發(fā)電需求。該項(xiàng)目于2023年5月8日正式投產(chǎn),歷經(jīng)兩年多穩(wěn)定運(yùn)行,成為西南地區(qū)煤礦瓦斯資源化利用的標(biāo)桿工程。

  As a well-established state-owned enterprise with a century of experience in the field of gas power generation, Jichai has developed biogas generator sets that are specifically adapted to low concentration gas scenarios in coal mines. The model selected for Yixing Coal Mine this time has a rated power of 1 MW per unit, and the actual power remains stable at 950-1000 kW when operating at full load. With 14 units synchronously generating power, it can achieve all-weather full load operation and fully meet the large-scale gas treatment and power generation needs of coal mines. The project was officially put into operation on May 8, 2023, and after more than two years of stable operation, it has become a benchmark project for the utilization of coal mine gas resources in the southwest region.

  硬核參數(shù)加持,讓濟(jì)柴機(jī)組在效率與環(huán)保上雙重在線(xiàn)。機(jī)組熱效率達(dá)40%,遠(yuǎn)超行業(yè)同類(lèi)機(jī)型平均水平,搭配精準(zhǔn)的空燃比閉環(huán)控制技術(shù),每度電油耗控制在0.3克以下,大幅降低運(yùn)維成本——按單臺(tái)機(jī)組日均滿(mǎn)負(fù)荷運(yùn)行22小時(shí)計(jì)算,單機(jī)日均發(fā)電量可達(dá)2.1萬(wàn)度,14臺(tái)機(jī)組年發(fā)電量可達(dá)105.66萬(wàn)度,能滿(mǎn)足約880戶(hù)家庭全年用電需求,經(jīng)濟(jì)效益十分可觀。

  With the support of hardcore parameters, the Jichai unit is able to achieve dual efficiency and environmental protection. The thermal efficiency of the unit reaches 40%, far exceeding the average level of similar models in the industry. Coupled with precise air-fuel ratio closed-loop control technology, the fuel consumption per kilowatt hour is controlled below 0.3 grams, significantly reducing operation and maintenance costs. Calculated based on a single unit operating at full load for 22 hours per day, the daily average power generation of a single unit can reach 21000 kilowatt hours, and the annual power generation of 14 units can reach 1.0566 million kilowatt hours, which can meet the annual electricity demand of about 880 households and has considerable economic benefits.

  環(huán)保性能同樣經(jīng)得起考驗(yàn),契合煤礦綠色生產(chǎn)要求。前期實(shí)測(cè)數(shù)據(jù)顯示,濟(jì)柴沼氣發(fā)電機(jī)組氮氧化合物排放量控制在500-800毫克每立方米,符合國(guó)家工業(yè)廢氣排放相關(guān)標(biāo)準(zhǔn),相較于傳統(tǒng)瓦斯處理方式,可大幅減少污染物排放。依托濟(jì)柴成熟的氣體適配技術(shù),機(jī)組能高效消化低濃度瓦斯,既消除煤礦瓦斯安全隱患,又實(shí)現(xiàn)清潔能源回收,真正做到“安全、環(huán)保、發(fā)電”三位一體。

  The environmental performance can also withstand the test and meet the requirements of green production in coal mines. Preliminary test data shows that the nitrogen oxide emissions of Jichai biogas generator units are controlled at 500-800 milligrams per cubic meter, which meets the relevant national standards for industrial waste gas emissions. Compared with traditional gas treatment methods, it can significantly reduce pollutant emissions. Relying on Jichai's mature gas adaptation technology, the unit can efficiently digest low concentration gas, eliminating coal mine gas safety hazards and achieving clean energy recovery, truly achieving the integration of "safety, environmental protection, and power generation".

  穩(wěn)定性是工業(yè)發(fā)電設(shè)備的核心競(jìng)爭(zhēng)力,濟(jì)柴機(jī)組用實(shí)踐交出了滿(mǎn)分答卷。宜興煤礦項(xiàng)目中,14臺(tái)濟(jì)柴機(jī)組持續(xù)穩(wěn)定運(yùn)行,未出現(xiàn)重大故障,故障率低于2%,遠(yuǎn)超行業(yè)平均水平。機(jī)組搭載濟(jì)柴自主研發(fā)的控制系統(tǒng),可精準(zhǔn)調(diào)控運(yùn)行參數(shù),適配煤礦瓦斯?jié)舛炔▌?dòng)場(chǎng)景,即便瓦斯?jié)舛瘸霈F(xiàn)小幅變化,也能保持功率穩(wěn)定輸出,避免發(fā)電中斷,保障電站持續(xù)收益。

  Stability is the core competitiveness of industrial power generation equipment, and Jichai unit has delivered a perfect score through practice. In the Yixing coal mine project, 14 Jichai units continued to operate stably without major failures, with a failure rate of less than 2%, far exceeding the industry average. The unit is equipped with a control system independently developed by Jichai, which can accurately regulate operating parameters and adapt to fluctuations in coal mine gas concentration. Even if there are slight changes in gas concentration, it can maintain stable power output, avoid power generation interruptions, and ensure the continuous income of the power station.

  作為國(guó)內(nèi)氣體發(fā)電裝備領(lǐng)域的領(lǐng)跑者,濟(jì)柴不僅有過(guò)硬的產(chǎn)品實(shí)力,更有全方位的服務(wù)支撐,這也是宜興煤礦選擇濟(jì)柴的核心原因之一。從項(xiàng)目建設(shè)階段的方案定制,到后期的安裝調(diào)試、運(yùn)維指導(dǎo),濟(jì)柴提供全流程專(zhuān)屬服務(wù),全程跟進(jìn)項(xiàng)目落地,助力14臺(tái)機(jī)組快速實(shí)現(xiàn)并網(wǎng)發(fā)電,大幅縮短項(xiàng)目投產(chǎn)周期,贏得了項(xiàng)目方的高度認(rèn)可。

  As a leader in the field of domestic gas power generation equipment, Jichai not only has excellent product strength, but also comprehensive service support, which is one of the core reasons why Yixing Coal Mine chose Jichai. From customized project construction plans to installation, debugging, and operation guidance in the later stages, Jichai provides exclusive services throughout the entire process, following up on project implementation and helping 14 units quickly achieve grid connected power generation, significantly shortening the project production cycle and winning high recognition from the project party.

  從行業(yè)價(jià)值來(lái)看,濟(jì)柴沼氣發(fā)電機(jī)組的應(yīng)用,為煤礦瓦斯資源化利用提供了可復(fù)制、可推廣的方案。我國(guó)煤礦瓦斯儲(chǔ)量豐富,若能廣泛推廣此類(lèi)機(jī)組,既能破解瓦斯安全與環(huán)保難題,又能補(bǔ)充清潔能源供應(yīng),契合“雙碳”發(fā)展趨勢(shì)。據(jù)悉,濟(jì)柴各類(lèi)氣體發(fā)電產(chǎn)品國(guó)內(nèi)市場(chǎng)占有率接近70%,總裝機(jī)容量超700兆瓦,年均減排二氧化碳600萬(wàn)噸,持續(xù)領(lǐng)跑行業(yè)發(fā)展。

  From the perspective of industry value, the application of Jichai biogas generator sets provides a replicable and promotable solution for the utilization of coal mine gas resources. China's coal mines have abundant gas reserves. If such units can be widely promoted, it can not only solve the problems of gas safety and environmental protection, but also supplement the supply of clean energy, which is in line with the trend of "dual carbon" development. It is reported that Jichai's various gas power generation products have a domestic market share of nearly 70%, with a total installed capacity of over 700 megawatts and an average annual reduction of 6 million tons of carbon dioxide, continuing to lead the industry's development.

  對(duì)比同類(lèi)品牌,濟(jì)柴沼氣發(fā)電機(jī)組憑借百年制造底蘊(yùn),在適配性、穩(wěn)定性上優(yōu)勢(shì)凸顯——既能適配煤礦低濃度瓦斯的復(fù)雜工況,又能實(shí)現(xiàn)高效發(fā)電、低碳排放,同時(shí)依托全流程服務(wù)保障,降低項(xiàng)目運(yùn)維風(fēng)險(xiǎn)。宜興煤礦項(xiàng)目的成功落地,不僅彰顯了濟(jì)柴“王牌動(dòng)力”的實(shí)力,更推動(dòng)煤礦行業(yè)向綠色、低碳、高效轉(zhuǎn)型。

  Compared with similar brands, Jichai biogas generator sets have outstanding advantages in adaptability and stability with a century of manufacturing experience - they can adapt to complex working conditions of low concentration gas in coal mines, achieve efficient power generation and low-carbon emissions, and rely on full process service guarantees to reduce project operation and maintenance risks. The successful implementation of the Yixing coal mine project not only demonstrates the strength of Jichai's "ace power", but also promotes the transformation of the coal mining industry towards green, low-carbon, and efficient.
