煤氣發(fā)電機組是以鋼鐵、化工等工業(yè)生產(chǎn)過程中產(chǎn)生的副產(chǎn)煤氣——包括高爐煤氣、焦?fàn)t煤氣、轉(zhuǎn)爐煤氣、礦熱爐煤氣等——為燃料進行發(fā)電的專用設(shè)備。煉鋼過程中產(chǎn)生的煤氣占鋼鐵生產(chǎn)二次能源的一半以上，是行業(yè)節(jié)能降碳的主要目標(biāo)。煤氣發(fā)電機組正是解決這一“廢氣”資源化利用問題的核心裝備。

Gas generator set is a specialized equipment that generates electricity using by-product gas generated in industrial production processes such as steel and chemical industry, including blast furnace gas, coke oven gas, converter gas, and ore blast furnace gas, as fuel. The gas generated during the steelmaking process accounts for more than half of the secondary energy used in steel production, and is the main goal of energy conservation and carbon reduction in the industry. The gas generator set is the core equipment to solve the problem of resource utilization of waste gas.

二、資源浪費問題：將“廢氣”變“綠電”

2、 The problem of resource waste: turning "waste gas" into "green electricity"

煤氣發(fā)電機組解決的首要問題是工業(yè)副產(chǎn)煤氣的巨大浪費。傳統(tǒng)上，大量高爐煤氣、轉(zhuǎn)爐煤氣被直接排空或簡單燃燒，既浪費了寶貴的能源，又造成了環(huán)境污染。煤氣發(fā)電機組通過出色燃燒這些低熱值煤氣，將其轉(zhuǎn)化為電能，實現(xiàn)了“變廢為寶”。以濟柴動力在廣東某鋼廠的實踐為例，10臺轉(zhuǎn)爐煤氣發(fā)電機組搭配氣體預(yù)處理、余熱回收和尾氣凈化裝置，已經(jīng)穩(wěn)定運行超過2800小時，煤氣回收利用率高達99%。

The primary problem solved by gas generators is the huge waste of industrial by-product gas. Traditionally, a large amount of blast furnace gas and converter gas have been directly discharged or simply burned, which not only wastes valuable energy but also causes environmental pollution. Gas generators efficiently burn these low calorific value gases and convert them into electrical energy, achieving the goal of "turning waste into treasure". Taking the practice of Jichai Power in a steel plant in Guangdong as an example, 10 converter gas generator units equipped with gas pretreatment, waste heat recovery, and exhaust gas purification devices have been running stably for more than 2800 hours, with a gas recovery utilization rate of up to 99%.

三、能源效率問題：突破傳統(tǒng)發(fā)電效率瓶頸

3、 Energy efficiency issue: breaking through the bottleneck of traditional power generation efficiency

煤氣發(fā)電機組解決的第二個問題是傳統(tǒng)煤氣利用方式效率低下的瓶頸。鋼鐵企業(yè)普遍采用的“鍋爐蒸汽驅(qū)動汽輪機發(fā)電”方式，在轉(zhuǎn)換效率、產(chǎn)能適配和建設(shè)周期方面都存在明顯短板。新型煤氣發(fā)電技術(shù)通過提升主蒸汽參數(shù)至超高溫/超高壓乃至超高溫/亞臨界，并廣泛應(yīng)用中間一次再熱技術(shù)，發(fā)電效率可達38%–40%，較傳統(tǒng)中溫中壓機組提高約13個百分點。首鋼工程公司的高參數(shù)小型化煤氣發(fā)電技術(shù)，發(fā)電效率可達雙超至亞臨界水平。濟柴動力的轉(zhuǎn)爐煤氣發(fā)電方案綜合能源利用效率達44%，比傳統(tǒng)發(fā)電解決方案提高近10個百分點。

The second problem solved by gas generators is the bottleneck of low efficiency in traditional gas utilization methods. The commonly used method of "boiler steam driven turbine power generation" in steel enterprises has obvious shortcomings in conversion efficiency, capacity adaptation, and construction period. The new gas power generation technology improves the main steam parameters to ultra-high temperature/ultra-high pressure or even ultra-high temperature/subcritical, and widely applies the intermediate reheating technology. The power generation efficiency can reach 38% -40%, which is about 13 percentage points higher than traditional medium temperature and medium pressure units. The high parameter miniaturized gas power generation technology of Shougang Engineering Company can achieve power generation efficiency ranging from double super to subcritical levels. The comprehensive energy utilization efficiency of Jichai Power's converter gas power generation solution reaches 44%, which is nearly 10 percentage points higher than traditional power generation solutions.

四、節(jié)能減排問題：助力“雙碳”目標(biāo)實現(xiàn)

4、 Energy conservation and emission reduction issues: helping achieve the "dual carbon" goal

煤氣發(fā)電機組直接助力鋼鐵等高耗能行業(yè)實現(xiàn)“雙碳”目標(biāo)。煤氣出色發(fā)電技術(shù)的應(yīng)用，減少了鋼鐵企業(yè)對外購電力的依賴，間接提升了碳減排能力。以某鋼廠為例，一年可回收電能1.2億度，減少二氧化碳排放9.8萬噸，直接創(chuàng)造經(jīng)濟效益5700多萬元。首鋼工程公司的超臨界煤氣發(fā)電技術(shù)發(fā)電效率可達43%-45.6%。漣鋼超超臨界煤氣發(fā)電技術(shù)，單臺150MW機組相比亞臨界發(fā)電機組多節(jié)約標(biāo)準(zhǔn)煤約3.2萬噸，減少二氧化碳排放約8.5萬噸以上。

Gas generators directly assist high energy consuming industries such as steel in achieving their "dual carbon" goals. The application of high-efficiency gas power generation technology has reduced the dependence of steel enterprises on purchased electricity, indirectly enhancing their carbon emission reduction capabilities. Taking a certain steel plant as an example, it can recover 120 million kilowatt hours of electricity per year, reduce carbon dioxide emissions by 98000 tons, and directly create economic benefits of over 57 million yuan. The power generation efficiency of Shougang Engineering Company's supercritical gas power generation technology can reach 43% -45.6%. Liangang's ultra supercritical gas power generation technology saves about 32000 tons of standard coal and reduces carbon dioxide emissions by more than 85000 tons per 150MW unit compared to subcritical power generation units.

五、建設(shè)周期與投資回報問題

5、 Construction period and investment return issues

煤氣發(fā)電機組還解決了傳統(tǒng)發(fā)電項目建設(shè)周期長、投資回收慢的問題。新型煤氣發(fā)電機組從設(shè)計到投產(chǎn)只需4到6個月，比傳統(tǒng)技術(shù)方案建設(shè)時間少60%，資金回收期縮短到1.5年。機組容量覆蓋35MW至150MW，可靈活匹配不同規(guī)模鋼鐵企業(yè)的煤氣資源量和場地條件，尤其適合老舊機組升級改造或新建分布式能源站。

Gas generator sets also solve the problems of long construction cycles and slow investment recovery in traditional power generation projects. The new gas-fired power generation unit only takes 4 to 6 months from design to operation, which is 60% less than the construction time of traditional technical solutions, and the payback period is shortened to 1.5 years. The unit capacity covers 35MW to 150MW, which can flexibly match the gas resources and site conditions of different scale steel enterprises, especially suitable for upgrading and renovating old units or building new distributed energy stations.
