在鋼鐵、焦化等重工業(yè)領(lǐng)域，焦化發(fā)電機(jī)組正成為能源循環(huán)利用的核心裝備。這類機(jī)組通過(guò)捕捉焦化副產(chǎn)的高爐煤氣、焦?fàn)t煤氣等可燃廢氣，將其轉(zhuǎn)化為清潔電能，既緩解了工業(yè)廢氣排放壓力，又開(kāi)辟了二次能源利用新路徑。

　　In heavy industries such as steel and coking, coking power generation units are becoming the core equipment for energy recycling. This type of unit captures combustible waste gases such as blast furnace gas and coke oven gas from coking by-products and converts them into clean electrical energy, which not only alleviates the pressure of industrial waste gas emissions but also opens up a new path for the utilization of secondary energy.

　　焦化過(guò)程中產(chǎn)生的高爐煤氣含有一氧化碳、氫氣等可燃成分，傳統(tǒng)處理方式多以燃燒排放為主，既浪費(fèi)能源又加劇碳排放。焦化發(fā)電機(jī)組采用燃?xì)廨啓C(jī)或內(nèi)燃機(jī)技術(shù)，將這類低熱值氣體引入燃燒室，通過(guò)精確控制空燃比實(shí)現(xiàn)穩(wěn)定燃燒。燃?xì)廨啓C(jī)機(jī)組利用高溫燃?xì)怛?qū)動(dòng)渦輪旋轉(zhuǎn)，帶動(dòng)發(fā)電機(jī)產(chǎn)生電能；內(nèi)燃機(jī)機(jī)組則通過(guò)活塞往復(fù)運(yùn)動(dòng)完成能量轉(zhuǎn)換，兩者均配備余熱回收裝置，將尾氣中的顯熱轉(zhuǎn)化為蒸汽或熱水，形成熱電聯(lián)產(chǎn)模式。

　　The blast furnace gas produced during the coking process contains combustible components such as carbon monoxide and hydrogen. Traditional treatment methods mainly rely on combustion emissions, which not only waste energy but also exacerbate carbon emissions. Coking power generation units use gas turbine or internal combustion engine technology to introduce low calorific value gases into the combustion chamber, and achieve stable combustion through precise control of air-fuel ratio. Gas turbine units use high-temperature gas to drive the turbine to rotate, driving the generator to generate electrical energy; The internal combustion engine unit completes energy conversion through the reciprocating motion of the piston, and both are equipped with waste heat recovery devices to convert the sensible heat in the exhaust into steam or hot water, forming a cogeneration mode.

　　在鋼鐵聯(lián)合企業(yè)，焦化發(fā)電機(jī)組與高爐、轉(zhuǎn)爐等工序形成能源閉環(huán)。高爐煤氣經(jīng)除塵、脫硫后進(jìn)入發(fā)電機(jī)組，產(chǎn)生的電力供廠區(qū)使用，余熱用于預(yù)熱助燃空氣或加熱原料。這種自給自足的能源模式，使企業(yè)外購(gòu)電量顯著降低，能源成本得到有效控制。部分先進(jìn)機(jī)組采用IGCC技術(shù)，將煤氣化合成清潔燃?xì)猓M(jìn)一步提升發(fā)電效率與環(huán)保性能。

　　In steel joint ventures, coking power generation units form an energy loop with processes such as blast furnaces and converters. After dust removal and desulfurization, blast furnace gas enters the generator set, and the generated electricity is used for the plant area. The waste heat is used to preheat the combustion air or heat the raw materials. This self-sufficient energy model significantly reduces the amount of electricity purchased by enterprises and effectively controls energy costs. Some advanced units adopt IGCC technology to synthesize clean gas through coal gasification, further improving power generation efficiency and environmental performance.

　　焦化發(fā)電機(jī)組的經(jīng)濟(jì)性源于廢氣零成本與政策補(bǔ)貼雙重驅(qū)動(dòng)。傳統(tǒng)處理方式需消耗大量能源進(jìn)行煤氣加壓、燃燒排放，而發(fā)電機(jī)組將這部分成本轉(zhuǎn)化為電力收益。隨著碳交易市場(chǎng)完善，機(jī)組減排量可轉(zhuǎn)化為可交易碳資產(chǎn)，形成新的利潤(rùn)增長(zhǎng)點(diǎn)。此外，機(jī)組運(yùn)行產(chǎn)生的蒸汽可替代燃煤鍋爐，減少企業(yè)燃料采購(gòu)支出。

　　The economy of coking power generation units is driven by both zero waste gas cost and policy subsidies. The traditional processing method requires a large amount of energy for gas pressurization and combustion emissions, and the generator set converts this cost into electricity revenue. With the improvement of the carbon trading market, the emission reduction of units can be converted into tradable carbon assets, forming new profit growth points. In addition, the steam generated by the operation of the unit can replace coal-fired boilers and reduce fuel procurement expenses for enterprises.

　　環(huán)保效益是焦化發(fā)電機(jī)組的核心價(jià)值。傳統(tǒng)焦化煤氣燃燒排放會(huì)產(chǎn)生大量二氧化碳及氮氧化物，而發(fā)電機(jī)組通過(guò)高效燃燒與尾氣凈化，使污染物排放濃度顯著降低。部分機(jī)組配置SCR脫硝裝置與布袋除塵器，使氮氧化物、粉塵排放優(yōu)于燃?xì)鈾C(jī)組標(biāo)準(zhǔn)。這種能源化利用方式，使工業(yè)廢氣從排放源轉(zhuǎn)變?yōu)榍鍧嵞茉摧d體。

　　Environmental benefits are the core value of coking power generation units. Traditional coking gas combustion emissions produce a large amount of carbon dioxide and nitrogen oxides, while generator sets significantly reduce pollutant emission concentrations through efficient combustion and exhaust gas purification. Some units are equipped with SCR denitrification devices and bag filters, which result in nitrogen oxide and dust emissions exceeding the standards of gas-fired units. This energy utilization method transforms industrial waste gas from an emission source into a clean energy carrier.

　　焦化發(fā)電機(jī)組通過(guò)技術(shù)創(chuàng)新，將工業(yè)廢氣轉(zhuǎn)化為綠色電能，重構(gòu)了傳統(tǒng)重工業(yè)的能源利用模式。其價(jià)值不僅體現(xiàn)在經(jīng)濟(jì)效益提升，更在于推動(dòng)高耗能行業(yè)向低碳轉(zhuǎn)型，為循環(huán)經(jīng)濟(jì)提供可復(fù)制的能源解決方案。隨著材料科學(xué)與控制技術(shù)的進(jìn)步，這類機(jī)組將在工業(yè)領(lǐng)域發(fā)揮更大的節(jié)能減排作用。

　　Coking power generation units have transformed industrial waste gas into green electricity through technological innovation, reconstructing the energy utilization mode of traditional heavy industry. Its value is not only reflected in the improvement of economic benefits, but also in promoting the low-carbon transformation of high energy consuming industries and providing replicable energy solutions for the circular economy. With the advancement of materials science and control technology, such units will play a greater role in energy conservation and emission reduction in the industrial field.
