在工業(yè)生產(chǎn)蓬勃發(fā)展的當(dāng)下，環(huán)保與能源利用的問題愈發(fā)凸顯。工業(yè)尾氣作為生產(chǎn)過程中的副產(chǎn)物，長(zhǎng)期以來被視作難以處理的 “廢棄物”，不僅造成了環(huán)境污染，還意味著能源的巨大浪費(fèi)。而工業(yè)尾氣發(fā)電機(jī)組的出現(xiàn)，宛如一道曙光，為解決這些難題提供了有效途徑，開啟了工業(yè)綠色發(fā)展的新篇章。

In the current booming industrial production, the issues of environmental protection and energy utilization have become increasingly prominent. Industrial exhaust gas, as a byproduct of the production process, has long been regarded as a difficult "waste" to deal with. It not only causes environmental pollution, but also means a huge waste of energy. The emergence of industrial exhaust gas generators is like a dawn, providing an effective way to solve these problems and opening a new chapter in industrial green development.

一、工作原理

1、 Working principle

工業(yè)尾氣發(fā)電機(jī)組主要由燃?xì)獍l(fā)動(dòng)機(jī)、發(fā)電機(jī)、控制系統(tǒng)和尾氣處理裝置等部分組成。其核心原理是利用工業(yè)生產(chǎn)中產(chǎn)生的可燃尾氣作為燃料，驅(qū)動(dòng)燃?xì)獍l(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)，進(jìn)而帶動(dòng)發(fā)電機(jī)發(fā)電。

The industrial exhaust gas generator set mainly consists of gas engines, generators, control systems, and exhaust gas treatment devices. The core principle is to use the combustible exhaust gas generated in industrial production as fuel to drive the operation of gas engines, and then drive generators to generate electricity.

具體而言，首先，尾氣從生產(chǎn)設(shè)備排出后，進(jìn)入尾氣處理裝置。在這里，尾氣中的雜質(zhì)、顆粒物和有害氣體被去除或轉(zhuǎn)化，以滿足燃?xì)獍l(fā)動(dòng)機(jī)對(duì)燃料的清潔度要求。例如，在處理含有硫化氫的尾氣時(shí)，會(huì)通過脫硫裝置將其轉(zhuǎn)化為無害的物質(zhì)，避免對(duì)設(shè)備造成腐蝕。

Specifically, firstly, the exhaust gas is discharged from the production equipment and enters the exhaust gas treatment device. Here, impurities, particulate matter, and harmful gases in the exhaust are removed or converted to meet the cleanliness requirements of gas engines for fuel. For example, when dealing with exhaust gas containing hydrogen sulfide, it will be converted into harmless substances through desulfurization devices to avoid corrosion of equipment.

凈化后的尾氣與適量的空氣混合，進(jìn)入燃?xì)獍l(fā)動(dòng)機(jī)的燃燒室。在燃燒室內(nèi)，混合氣被火花塞點(diǎn)燃，發(fā)生劇烈的燃燒反應(yīng)，產(chǎn)生高溫高壓的燃?xì)?。這些燃?xì)庋杆倥蛎洠苿?dòng)活塞在氣缸內(nèi)做往復(fù)直線運(yùn)動(dòng)，將燃?xì)獾臒崮苻D(zhuǎn)化為機(jī)械能?；钊耐鶑?fù)運(yùn)動(dòng)通過連桿傳遞給曲軸，使曲軸做旋轉(zhuǎn)運(yùn)動(dòng)。

The purified exhaust gas is mixed with an appropriate amount of air and enters the combustion chamber of the gas engine. In the combustion chamber, the mixture is ignited by a spark plug, causing a violent combustion reaction and producing high-temperature and high-pressure gas. These gases rapidly expand, pushing the piston to make reciprocating linear motion inside the cylinder, converting the thermal energy of the gases into mechanical energy. The reciprocating motion of the piston is transmitted to the crankshaft through the connecting rod, causing the crankshaft to rotate.

曲軸與發(fā)電機(jī)的轉(zhuǎn)子相連，帶動(dòng)轉(zhuǎn)子在定子的磁場(chǎng)中高速旋轉(zhuǎn)。根據(jù)電磁感應(yīng)原理，在定子繞組中產(chǎn)生感應(yīng)電動(dòng)勢(shì)，從而輸出電能。整個(gè)過程中，控制系統(tǒng)發(fā)揮著關(guān)鍵作用，實(shí)時(shí)監(jiān)測(cè)和調(diào)控機(jī)組的運(yùn)行參數(shù)，確保設(shè)備穩(wěn)定、高效運(yùn)行。

The crankshaft is connected to the rotor of the generator, driving the rotor to rotate at high speed in the magnetic field of the stator. According to the principle of electromagnetic induction, induced electromotive force is generated in the stator winding, thereby outputting electrical energy. Throughout the process, the control system plays a crucial role in real-time monitoring and regulating the operating parameters of the unit, ensuring stable and efficient operation of the equipment.

二、顯著優(yōu)勢(shì)

2、 Significant advantages

（一）節(jié)能減排

（1） Energy conservation and emission reduction

工業(yè)尾氣中通常含有一氧化碳、氫氣、甲烷等可燃成分，直接排放到大氣中不僅會(huì)造成環(huán)境污染，還浪費(fèi)了大量能源。工業(yè)尾氣發(fā)電機(jī)組將這些尾氣轉(zhuǎn)化為電能，實(shí)現(xiàn)了能源的二次利用，減少了對(duì)傳統(tǒng)化石能源的依賴，降低了碳排放。以鐵合金生產(chǎn)為例，每噸硅錳合金可產(chǎn)生 960 - 1100nm3 的尾氣，若采用尾氣發(fā)電機(jī)組，按照一方氣發(fā)一度電計(jì)算，可發(fā)電近千度，極大地減少了能源消耗和溫室氣體排放。

Industrial exhaust gas usually contains combustible components such as carbon monoxide, hydrogen, methane, etc. Direct discharge into the atmosphere not only causes environmental pollution, but also wastes a lot of energy. The industrial exhaust gas generator unit converts these exhaust gases into electrical energy, realizing the secondary utilization of energy, reducing dependence on traditional fossil fuels, and lowering carbon emissions. Taking the production of ferroalloys as an example, each ton of silicon manganese alloy can generate 960-1100nm 3 of exhaust gas. If an exhaust gas generator unit is used, it can generate nearly 1000 kWh of electricity per cubic meter of gas, greatly reducing energy consumption and greenhouse gas emissions.

（二）降低成本

（2） Reduce costs

對(duì)于工業(yè)企業(yè)來說，使用工業(yè)尾氣發(fā)電機(jī)組可以降低用電成本。企業(yè)利用自身產(chǎn)生的尾氣發(fā)電，減少了從電網(wǎng)購(gòu)電的需求，尤其是對(duì)于一些高能耗企業(yè)，這一成本降低效應(yīng)更為顯著。同時(shí)，減少尾氣排放也避免了可能面臨的環(huán)保罰款，從多個(gè)角度為企業(yè)節(jié)省了開支。

For industrial enterprises, using industrial exhaust gas generators can reduce electricity costs. Enterprises use their own exhaust gas to generate electricity, reducing the demand for purchasing electricity from the grid, especially for some high energy consuming enterprises, this cost reduction effect is more significant. At the same time, reducing exhaust emissions also avoids potential environmental fines and saves expenses for businesses from multiple perspectives.

（三）靈活便捷

（3） Flexible and convenient

工業(yè)尾氣發(fā)電機(jī)組的安裝和調(diào)試相對(duì)簡(jiǎn)便，占地面積較小，可根據(jù)企業(yè)的實(shí)際需求和場(chǎng)地條件進(jìn)行靈活配置。無論是大型工業(yè)企業(yè)，還是小型工廠，都能找到適合自身規(guī)模的尾氣發(fā)電解決方案。而且，其啟動(dòng)速度較快，能夠在短時(shí)間內(nèi)響應(yīng)電力需求的變化，滿足企業(yè)的應(yīng)急用電需求。

The installation and commissioning of industrial exhaust gas generator sets are relatively simple, with a small footprint, and can be flexibly configured according to the actual needs of enterprises and site conditions. Both large industrial enterprises and small factories can find exhaust power generation solutions that are suitable for their own scale. Moreover, it has a fast start-up speed and can respond to changes in power demand in a short period of time, meeting the emergency power needs of enterprises.

（四）促進(jìn)循環(huán)經(jīng)濟(jì)發(fā)展

（4） Promote the development of circular economy

工業(yè)尾氣發(fā)電是循環(huán)經(jīng)濟(jì)理念在工業(yè)領(lǐng)域的生動(dòng)實(shí)踐。通過回收利用尾氣中的能源，實(shí)現(xiàn)了資源的高效利用和廢棄物的減量化，形成了 “資源 - 生產(chǎn) - 廢棄物 - 再利用” 的良性循環(huán)，推動(dòng)了工業(yè)企業(yè)向綠色、可持續(xù)方向發(fā)展。

Industrial exhaust gas power generation is a vivid practice of the circular economy concept in the industrial field. By recycling energy from exhaust gases, efficient utilization of resources and reduction of waste have been achieved, forming a virtuous cycle of "resources production waste reuse" and promoting the development of industrial enterprises towards green and sustainable directions.

三、應(yīng)用領(lǐng)域

3、 Application Fields

（一）鐵合金行業(yè)

（1） Ferroalloy industry

鐵合金生產(chǎn)過程中會(huì)產(chǎn)生大量富含一氧化碳和氫氣的尾氣。如硅錳合金、高碳鉻鐵、硅鐵等生產(chǎn)環(huán)節(jié)，尾氣產(chǎn)量巨大。這些尾氣通過工業(yè)尾氣發(fā)電機(jī)組進(jìn)行發(fā)電，不僅解決了尾氣排放問題，還為企業(yè)提供了可觀的電力資源，降低了企業(yè)的用電成本，提高了企業(yè)的經(jīng)濟(jì)效益和市場(chǎng)競(jìng)爭(zhēng)力。

During the production process of ferroalloys, a large amount of exhaust gas rich in carbon monoxide and hydrogen is generated. The production processes of silicon manganese alloy, high carbon ferrochrome, ferrosilicon, etc. have a huge output of exhaust gas. These exhaust gases are generated by industrial exhaust gas generators, which not only solve the problem of exhaust emissions, but also provide considerable power resources for enterprises, reduce their electricity costs, and improve their economic benefits and market competitiveness.

（二）焦炭和蘭炭行業(yè)

（2） Coke and Blue Charcoal Industry

在焦炭和蘭炭生產(chǎn)過程中，會(huì)產(chǎn)生大量的干餾煤氣，主要成分包括氫氣、一氧化碳和甲烷等。這些煤氣以往大多被直接排空或低效燃燒，造成了嚴(yán)重的能源浪費(fèi)和環(huán)境污染。如今，利用工業(yè)尾氣發(fā)電機(jī)組，將這些煤氣轉(zhuǎn)化為電能，實(shí)現(xiàn)了能源的有效回收利用，減少了對(duì)環(huán)境的污染。

In the production process of coke and blue coke, a large amount of dry distillation gas is generated, mainly composed of hydrogen, carbon monoxide, and methane. These gases were mostly directly discharged or burned inefficiently in the past, causing serious energy waste and environmental pollution. Nowadays, the use of industrial exhaust gas generators to convert these gases into electrical energy has achieved effective energy recycling and reduced environmental pollution.

（三）化工行業(yè)

（3） Chemical industry

化工生產(chǎn)涉及眾多復(fù)雜的化學(xué)反應(yīng)，會(huì)產(chǎn)生各種類型的尾氣。例如，在電石生產(chǎn)中產(chǎn)生的電石尾氣，含有大量的一氧化碳；在一些有機(jī)合成反應(yīng)中，會(huì)產(chǎn)生富含甲烷、氫氣等可燃?xì)怏w的尾氣。工業(yè)尾氣發(fā)電機(jī)組可以針對(duì)不同化工尾氣的特點(diǎn)進(jìn)行優(yōu)化設(shè)計(jì)，實(shí)現(xiàn)尾氣的資源化利用，為化工企業(yè)帶來經(jīng)濟(jì)效益和環(huán)境效益。

Chemical production involves numerous complex chemical reactions that produce various types of exhaust gases. For example, the calcium carbide tail gas generated in the production of calcium carbide contains a large amount of carbon monoxide; In some organic synthesis reactions, exhaust gases rich in combustible gases such as methane and hydrogen are produced. Industrial exhaust gas generator sets can be optimized and designed according to the characteristics of different chemical exhaust gases, achieving the resource utilization of exhaust gases and bringing economic and environmental benefits to chemical enterprises.

（四）鋼鐵行業(yè)

（4） Steel industry

鋼鐵生產(chǎn)中的高爐煤氣和轉(zhuǎn)爐煤氣也是重要的工業(yè)尾氣資源。高爐煤氣熱值較低，但產(chǎn)量巨大；轉(zhuǎn)爐煤氣則具有較高的熱值。通過合理的技術(shù)手段，將這些煤氣引入工業(yè)尾氣發(fā)電機(jī)組進(jìn)行發(fā)電，不僅可以減少鋼鐵企業(yè)的能源消耗，還能降低對(duì)外部電力的依賴，提高企業(yè)的能源自給率。

Blast furnace gas and converter gas in steel production are also important industrial exhaust resources. The calorific value of blast furnace gas is low, but the output is huge; Converter gas has a higher calorific value. By using reasonable technological means, introducing these gases into industrial exhaust gas generators for power generation can not only reduce the energy consumption of steel enterprises, but also reduce their dependence on external electricity and improve their energy self-sufficiency rate.

四、技術(shù)挑戰(zhàn)與應(yīng)對(duì)策略

4、 Technical Challenges and Response Strategies

（一）尾氣成分復(fù)雜

（1） The exhaust composition is complex

工業(yè)尾氣成分復(fù)雜多樣，不同行業(yè)、不同生產(chǎn)工藝產(chǎn)生的尾氣成分差異很大，且常常含有雜質(zhì)、腐蝕性氣體和顆粒物等。這對(duì)尾氣處理技術(shù)和發(fā)電機(jī)組的適應(yīng)性提出了很高的要求。例如，高含氫尾氣容易導(dǎo)致內(nèi)燃機(jī)回火，影響設(shè)備的可靠性和穩(wěn)定性。

The composition of industrial exhaust gas is complex and diverse, and the exhaust gas generated by different industries and production processes varies greatly, often containing impurities, corrosive gases, and particulate matter. This places high demands on the adaptability of exhaust gas treatment technology and generator sets. For example, high hydrogen content exhaust gas can easily cause internal combustion engine backfire, affecting the reliability and stability of the equipment.

應(yīng)對(duì)策略是研發(fā)針對(duì)性的尾氣凈化技術(shù)和適應(yīng)性強(qiáng)的發(fā)電機(jī)組。如采用先進(jìn)的脫硫、脫硝、除塵技術(shù)，去除尾氣中的有害成分；開發(fā)專門針對(duì)高含氫尾氣的燃燒技術(shù)，如科美控股的雙路進(jìn)氣雙增壓、單缸控制、缸內(nèi)混合等技術(shù)，有效解決了高含氫尾氣燃燒不穩(wěn)定的問題。

The response strategy is to develop targeted exhaust gas purification technology and adaptable generator sets. If advanced desulfurization, denitrification, and dust removal technologies are used to remove harmful components from exhaust gas; Developing combustion technologies specifically for high hydrogen exhaust gases, such as dual intake and dual boost, single cylinder control, and in cylinder mixing technologies from Kemei Holdings, effectively solves the problem of unstable combustion in high hydrogen exhaust gases.

（二）發(fā)電效率有待提高

（2） Power generation efficiency needs to be improved

目前，部分工業(yè)尾氣發(fā)電機(jī)組的發(fā)電效率還相對(duì)較低，影響了能源的有效利用和企業(yè)的經(jīng)濟(jì)效益。這主要是由于尾氣的低熱值特性以及發(fā)電設(shè)備本身的技術(shù)限制。

At present, the power generation efficiency of some industrial exhaust gas generators is relatively low, which affects the effective utilization of energy and the economic benefits of enterprises. This is mainly due to the low calorific value characteristics of exhaust gas and the technical limitations of the power generation equipment itself.

為提高發(fā)電效率，一方面需要不斷優(yōu)化燃?xì)獍l(fā)動(dòng)機(jī)的燃燒過程，提高熱效率；另一方面，可以采用聯(lián)合循環(huán)發(fā)電技術(shù)，將尾氣發(fā)電與余熱回收利用相結(jié)合，實(shí)現(xiàn)能源的梯級(jí)利用。例如，通過余熱鍋爐將發(fā)電過程中產(chǎn)生的余熱轉(zhuǎn)化為蒸汽，用于供熱或驅(qū)動(dòng)蒸汽輪機(jī)發(fā)電，進(jìn)一步提高能源利用率。

To improve power generation efficiency, on the one hand, it is necessary to continuously optimize the combustion process of gas engines and improve thermal efficiency; On the other hand, combined cycle power generation technology can be used to combine tail gas power generation with waste heat recovery and utilization, achieving cascading energy utilization. For example, by using a waste heat boiler to convert the waste heat generated during the power generation process into steam, it can be used for heating or driving steam turbines to generate electricity, further improving energy utilization efficiency.

（三）設(shè)備維護(hù)成本高

（3） High equipment maintenance costs

工業(yè)尾氣發(fā)電機(jī)組在運(yùn)行過程中，由于尾氣的腐蝕性和雜質(zhì)的影響，設(shè)備的磨損和故障率相對(duì)較高，導(dǎo)致維護(hù)成本增加。而且，一些關(guān)鍵零部件可能需要從國(guó)外進(jìn)口，進(jìn)一步提高了維護(hù)成本和維修周期。

During the operation of industrial exhaust gas generators, due to the corrosiveness and impurities of the exhaust gas, the wear and failure rate of the equipment is relatively high, resulting in increased maintenance costs. Moreover, some key components may need to be imported from abroad, further increasing maintenance costs and repair cycles.

為降低設(shè)備維護(hù)成本，需要加強(qiáng)設(shè)備的日常維護(hù)和保養(yǎng)，定期檢查設(shè)備的運(yùn)行狀況，及時(shí)更換易損件。同時(shí)，加大國(guó)內(nèi)關(guān)鍵零部件的研發(fā)和生產(chǎn)力度，提高零部件的國(guó)產(chǎn)化率，降低采購(gòu)成本和維修周期。

To reduce equipment maintenance costs, it is necessary to strengthen the daily maintenance and upkeep of equipment, regularly check the operation status of equipment, and replace vulnerable parts in a timely manner. At the same time, we will increase the research and production efforts of key domestic components, improve the localization rate of components, and reduce procurement costs and maintenance cycles.

五、發(fā)展前景

5、 Development prospects

隨著全球?qū)Νh(huán)境保護(hù)和可持續(xù)發(fā)展的關(guān)注度不斷提高，以及 “雙碳” 目標(biāo)的推進(jìn)，工業(yè)尾氣發(fā)電機(jī)組的市場(chǎng)前景十分廣闊。未來，工業(yè)尾氣發(fā)電技術(shù)將朝著更高效率、更低成本、更智能化的方向發(fā)展。

With the increasing global attention to environmental protection and sustainable development, as well as the promotion of the "dual carbon" goal, the market prospects for industrial exhaust gas generators are very broad. In the future, industrial exhaust power generation technology will develop towards higher efficiency, lower cost, and greater intelligence.

在技術(shù)創(chuàng)新方面，新的尾氣處理技術(shù)、燃燒技術(shù)和發(fā)電技術(shù)將不斷涌現(xiàn)，進(jìn)一步提高尾氣發(fā)電的效率和可靠性。例如，隨著人工智能、物聯(lián)網(wǎng)等技術(shù)的發(fā)展，工業(yè)尾氣發(fā)電機(jī)組將實(shí)現(xiàn)智能化監(jiān)控和管理，通過遠(yuǎn)程監(jiān)控系統(tǒng)實(shí)時(shí)掌握設(shè)備的運(yùn)行狀態(tài)，及時(shí)發(fā)現(xiàn)并解決故障，提高設(shè)備的運(yùn)維效率。

In terms of technological innovation, new exhaust treatment technologies, combustion technologies, and power generation technologies will continue to emerge, further improving the efficiency and reliability of exhaust power generation. For example, with the development of technologies such as artificial intelligence and the Internet of Things, industrial exhaust gas generators will achieve intelligent monitoring and management. Through remote monitoring systems, the real-time operation status of the equipment can be monitored, faults can be detected and resolved in a timely manner, and the operation and maintenance efficiency of the equipment can be improved.

在市場(chǎng)應(yīng)用方面，工業(yè)尾氣發(fā)電將在更多行業(yè)得到推廣應(yīng)用，不僅局限于傳統(tǒng)的高能耗行業(yè)，一些新興產(chǎn)業(yè)如新能源汽車電池材料生產(chǎn)等行業(yè)也可能引入尾氣發(fā)電技術(shù)，實(shí)現(xiàn)能源的循環(huán)利用。同時(shí)，隨著環(huán)保政策的日益嚴(yán)格，企業(yè)對(duì)尾氣處理和能源利用的需求將不斷增加，為工業(yè)尾氣發(fā)電機(jī)組的發(fā)展提供了強(qiáng)大的市場(chǎng)動(dòng)力。

In terms of market application, industrial exhaust power generation will be promoted and applied in more industries, not limited to traditional high energy consuming industries. Some emerging industries such as the production of new energy vehicle battery materials may also introduce exhaust power generation technology to achieve energy recycling. Meanwhile, with the increasingly strict environmental policies, the demand for exhaust gas treatment and energy utilization from enterprises will continue to increase, providing strong market momentum for the development of industrial exhaust gas generators.

工業(yè)尾氣發(fā)電機(jī)組作為一種實(shí)現(xiàn)工業(yè)尾氣資源化利用的重要設(shè)備，在節(jié)能減排、降低成本、促進(jìn)循環(huán)經(jīng)濟(jì)發(fā)展等方面發(fā)揮著重要作用。盡管目前還面臨一些技術(shù)挑戰(zhàn)，但隨著技術(shù)的不斷進(jìn)步和市場(chǎng)的逐步成熟，其必將在工業(yè)綠色轉(zhuǎn)型的道路上發(fā)揮更大的作用，為構(gòu)建綠色、低碳的工業(yè)體系做出重要貢獻(xiàn)。

The industrial exhaust gas generator set, as an important equipment for realizing the resource utilization of industrial exhaust gas, plays an important role in energy conservation, emission reduction, cost reduction, and promoting the development of circular economy. Although there are still some technological challenges at present, with the continuous progress of technology and the gradual maturity of the market, it will play a greater role in the path of industrial green transformation and make important contributions to building a green and low-carbon industrial system.
