　　Core reveal! The six key factors for stable operation of biogas generators are indispensable

　　隨著沼氣資源化利用的不斷推進(jìn)，沼氣發(fā)電機組（Biogas Generator Set）已成為環(huán)保、工業(yè)領(lǐng)域?qū)崿F(xiàn)“變廢為寶”的核心裝備，其穩(wěn)定運行直接決定沼氣能源轉(zhuǎn)化效率與設(shè)備使用壽命。據(jù)行業(yè)數(shù)據(jù)顯示，超60%的沼氣發(fā)電機組故障源于核心系統(tǒng)配置不當(dāng)或操作不規(guī)范，其中脫硫不徹底、進(jìn)氣比例失衡等問題占比超45%。本文結(jié)合沼氣發(fā)電機組的六大核心組成系統(tǒng)，拆解其工作原理與技術(shù)要點，助力行業(yè)從業(yè)者精準(zhǔn)掌握設(shè)備運行關(guān)鍵，提升能源利用效率，規(guī)避運行隱患。

　　With the continuous promotion of biogas resource utilization, biogas generator sets have become the core equipment for environmental protection and industrial fields to achieve "turning waste into treasure". Their stable operation directly determines the efficiency of biogas energy conversion and the service life of equipment. According to industry data, over 60% of biogas generator failures are caused by improper configuration or improper operation of the core system, with over 45% of them being due to incomplete desulfurization and imbalanced intake ratio. This article combines the six core components of biogas generator sets, disassembles their working principles and technical points, and helps industry practitioners accurately grasp the key equipment operation, improve energy utilization efficiency, and avoid operational hazards.

　　作為沼氣發(fā)電機組的“第一道防護(hù)線”，沼氣脫硫及穩(wěn)壓、防爆設(shè)備直接決定設(shè)備使用壽命。沼氣中含有的硫化氫具有強腐蝕性，若不經(jīng)過脫硫處理直接通入發(fā)動機，會加速氣缸、管道的腐蝕老化，縮短設(shè)備使用壽命30%以上。因此，供沼氣發(fā)電機使用的沼氣需先經(jīng)過脫硫設(shè)備，將硫化氫濃度降至設(shè)備允許范圍，從源頭規(guī)避腐蝕風(fēng)險。同時，沼氣進(jìn)氣管路上需設(shè)置穩(wěn)壓設(shè)備，精準(zhǔn)調(diào)整沼氣流量，確?？諝馀c沼氣達(dá)到最佳空燃比，保障燃燒效率；此外，為防止進(jìn)氣管回火引發(fā)安全事故，需在沼氣總管上安裝防回火與防爆設(shè)備，筑牢設(shè)備運行安全防線。

　　As the "first line of protection" for biogas generators, biogas desulfurization, voltage stabilization, and explosion-proof equipment directly determine the service life of the equipment. The hydrogen sulfide contained in biogas has strong corrosiveness. If it is directly introduced into the engine without desulfurization treatment, it will accelerate the corrosion and aging of cylinders and pipelines, and shorten the service life of equipment by more than 30%. Therefore, the biogas used for biogas generators needs to first pass through desulfurization equipment to reduce the concentration of hydrogen sulfide to the allowable range of the equipment, in order to avoid corrosion risks from the source. At the same time, pressure stabilizing equipment should be installed on the biogas inlet pipeline to accurately adjust the biogas flow rate, ensuring the optimal air-fuel ratio between air and biogas and guaranteeing combustion efficiency; In addition, to prevent safety accidents caused by backfire of the intake pipe, it is necessary to install anti backfire and explosion-proof equipment on the biogas main pipe to establish a strong defense line for equipment operation safety.

　　進(jìn)氣調(diào)整體系與發(fā)動機焚燒體系，是保障沼氣發(fā)電機組高效運轉(zhuǎn)的核心。進(jìn)氣總管上配備的精準(zhǔn)、靈敏燃?xì)饣旌掀?，可根?jù)發(fā)動機運行負(fù)荷，實時調(diào)整空氣與沼氣的混合比例，避免因混合比例失衡導(dǎo)致的燃燒不充分、能源浪費等問題，據(jù)實測，合理調(diào)整混合比例可提升沼氣利用效率15%-20%。由于沼氣燃燒速度慢，相較于傳統(tǒng)汽油、柴油及天然氣發(fā)電機組，其發(fā)動機焚燒體系需進(jìn)行針對性改造，優(yōu)化點火系統(tǒng)性能，提升焚燒效率，減少后燃燒現(xiàn)象，既能降低能源損耗，也能有效延長發(fā)動機運行壽命。

　　The intake adjustment system and engine combustion system are the core to ensure the efficient operation of biogas generators. The precise and sensitive gas mixer equipped on the intake manifold can adjust the mixing ratio of air and biogas in real time according to the engine operating load, avoiding problems such as insufficient combustion and energy waste caused by imbalanced mixing ratios. According to actual tests, adjusting the mixing ratio reasonably can improve biogas utilization efficiency by 15% -20%. Due to the slow combustion rate of biogas, compared to traditional gasoline, diesel, and natural gas generator sets, its engine incineration system needs to be modified in a targeted manner to optimize ignition system performance, improve incineration efficiency, and reduce post combustion phenomena. This can not only reduce energy loss but also effectively extend the engine's operating life.

　　調(diào)速體系與預(yù)熱運用體系，進(jìn)一步提升了沼氣發(fā)電機組的穩(wěn)定性與能源利用率。若沼氣發(fā)電機組單獨運行，用電設(shè)備的并入與卸載會導(dǎo)致發(fā)電機負(fù)荷波動，極易影響設(shè)備正常運行，因此調(diào)速體系必不可少，其可實時響應(yīng)負(fù)荷變化，穩(wěn)定機組運行轉(zhuǎn)速，確保發(fā)電質(zhì)量達(dá)標(biāo)。預(yù)熱運用設(shè)備則可回收發(fā)動機冷卻水與排氣中的熱量，實現(xiàn)余熱再利用，大幅提升沼氣的能源利用效率，據(jù)行業(yè)統(tǒng)計，配備預(yù)熱運用系統(tǒng)的機組，綜合能源利用率可提升至85%以上，實現(xiàn)節(jié)能降耗的雙重目標(biāo)。

　　The speed control system and preheating application system further enhance the stability and energy utilization efficiency of biogas generators. If the biogas generator unit operates independently, the integration and unloading of electrical equipment will cause fluctuations in the generator load, which can easily affect the normal operation of the equipment. Therefore, a speed control system is essential, which can respond to load changes in real time, stabilize the operating speed of the unit, and ensure that the power generation quality meets the standards. Preheating equipment can recover heat from engine cooling water and exhaust, achieving waste heat reuse and greatly improving the energy utilization efficiency of biogas. According to industry statistics, units equipped with preheating systems can increase the comprehensive energy utilization rate to over 85%, achieving the dual goal of energy conservation and consumption reduction.

　　并網(wǎng)控制體系是沼氣發(fā)電機組實現(xiàn)規(guī)?；╇姷年P(guān)鍵支撐，其組成復(fù)雜、專業(yè)性強，主要包含發(fā)電機調(diào)壓電路、自動準(zhǔn)同期并列控制電路、手動并列和解列控制電路、測量電路及燃?xì)獍l(fā)動機輔助設(shè)備控制電路等。完善的并網(wǎng)控制體系可實現(xiàn)發(fā)電機組的精準(zhǔn)調(diào)壓、平穩(wěn)并網(wǎng)，確保發(fā)電量穩(wěn)定輸入電網(wǎng)，同時便于工作人員實時監(jiān)測設(shè)備運行數(shù)據(jù)，及時排查故障，提升設(shè)備運行的可控性與安全性，適配工業(yè)生產(chǎn)、污水處理廠等規(guī)?；╇妶鼍?。

　　The grid connected control system is a key support for the large-scale power supply of biogas generators. Its composition is complex and highly specialized, mainly including generator voltage regulation circuit, automatic quasi synchronous parallel control circuit, manual parallel and uncoupling control circuit, measurement circuit, and gas engine auxiliary equipment control circuit. A comprehensive grid control system can achieve precise voltage regulation and smooth grid connection of generator units, ensuring stable input of power generation into the grid. At the same time, it facilitates real-time monitoring of equipment operation data by staff, timely troubleshooting, and improves the controllability and safety of equipment operation, adapting to large-scale power supply scenarios such as industrial production and sewage treatment plants.

　　At present, China's biogas power generation technology has become mature, and biogas generator sets are widely used in sewage treatment plants, breeding farms, industrial parks and other fields due to their advantages of simple structure, convenient operation, energy conservation and environmental protection. It is reported that a complete biogas generator set, with six core systems operating in coordination, can achieve efficient conversion of biogas energy. The annual power generation of a single unit can reach over 1.8 million kWh, while reducing methane emissions and helping to achieve the "dual carbon" goal. Mastering the technical key points of these six core systems can not only avoid equipment operation failures, but also maximize the energy conversion value of biogas generators and promote the high-quality development of the biogas resource utilization industry.
