喚醒“工業尾氣”，驅動綠色未來

　　Awaken the 'industrial exhaust' and drive a green future

　　在鋼鐵廠的巨型高爐旁,除了熾熱的鐵水,還有一股看不見的龐大能量在持續不斷地產生—高爐煤氣。過去,高爐煤氣被視作廢氣直接排放或焚燒,既造成能源浪費,也加重環保負擔。如今,借助先進的技術,昔日的工業尾氣正被高效回收,轉化為驅動生產的綠色電能。今天,就讓我們一起揭開高爐煤氣發電的神秘面紗。

　　Beside the giant blast furnace in the steel plant, in addition to the hot molten iron, there is also an invisible and massive energy continuously produced - blast furnace gas. In the past, blast furnace gas was treated as waste gas and directly discharged or incinerated, which not only caused energy waste but also increased the burden on environmental protection. Nowadays, with the help of advanced technology, industrial exhaust gases from the past are being efficiently recovered and converted into green electricity to drive production. Today, let's unveil the mysterious veil of blast furnace gas power generation together.

　　01高爐煤氣：從“必然副產”到“城市能源”#

　　01 Blast furnace gas: from "inevitable byproduct" to "urban energy"#

　　高爐煤氣并非特意制造,而是高爐煉鐵過程中自然生成的副產物。當焦炭和煤粉在千度高溫下還原鐵礦石時,會產生大量以一氧化碳（CO）和氫氣（H?）為主的可燃氣體,也就是高爐煤氣 。然而,它天生“體質特殊”：熱值低（約為天然氣的十分之一）,成分復雜（含有粉塵、硫化物等雜質）。但其產量極為可觀,每生產1噸鐵水,大約會產生1500-2000立方米的高爐煤氣。作為鋼鐵大國,我國高爐煤氣年產生量高達數千億立方米,正因如此,它被稱作“未被看見的能源寶藏”。

　　Blast furnace gas is not intentionally produced, but a byproduct naturally generated during the process of blast furnace ironmaking. When coke and coal powder reduce iron ore at a high temperature of 1000 degrees, a large amount of combustible gases, mainly carbon monoxide (CO) and hydrogen (H?), are produced, which is blast furnace gas. However, it is born with a unique constitution: low calorific value (about one tenth of natural gas) and complex composition (containing impurities such as dust and sulfides). But its output is extremely considerable, producing about 1500-2000 cubic meters of blast furnace gas for every ton of molten iron produced. As a major steel producing country, China's annual production of blast furnace gas reaches hundreds of billions of cubic meters, which is why it is known as the 'unseen energy treasure'.

　　過去高爐煤氣是棘手廢氣,現在它是綠色能源。隨著技術和理念的升級,高爐煤氣高效回收已成為鋼鐵企業實現循環經濟的關鍵一環,其回收利用率甚至成為衡量企業綠色發展水平的重要指標。

　　In the past, blast furnace gas was a tricky waste gas, but now it is a green energy source. With the upgrading of technology and concepts, efficient recovery of blast furnace gas has become a key link for steel enterprises to achieve a circular economy, and its recovery and utilization rate has even become an important indicator for measuring the level of green development of enterprises.

　　02凈化：從“粗獷”到“精制”的必經之路

　　02 Purification: The necessary path from "rough" to "refined"

　　如同礦石需要冶煉才能成材,剛出爐的高爐煤氣也必須經過嚴格的凈化“洗禮”,才能成為發電設備的優質“食糧”。煤氣凈化主要包括脫硫、除塵、除焦等關鍵環節,目的是要確保氣體的安全性與清潔度。

　　Just as ore needs to be refined to become material, freshly produced blast furnace gas must also undergo strict purification and "baptism" in order to become high-quality "food" for power generation equipment. Gas purification mainly includes key processes such as desulfurization, dust removal, and coke removal, with the aim of ensuring the safety and cleanliness of the gas.

　　經過高效凈化,煤氣中的粉塵、焦油、硫化物等有害物質被大幅去除,氧氣含量嚴格控制在安全范圍內,氣體既潔凈又安全,為后續發電系統的高效轉化和穩定運行奠定了基礎。

　　After efficient purification, harmful substances such as dust, tar, and sulfides in the gas are greatly removed, and the oxygen content is strictly controlled within a safe range. The gas is both clean and safe, laying the foundation for the efficient conversion and stable operation of the subsequent power generation system.

　　03發電：將氣體轉化為光與熱#

　　03 Power Generation: Converting Gas into Light and Heat#

　　凈化后的高爐煤氣,最主要的應用方向之一就是發電。在眾多發電技術中,燃氣內燃機發電因其獨特的優勢,受到中小型鋼鐵企業的青睞。燃氣內燃式發電機組就像一套高度集成的“能源心臟”,將清潔煤氣作為燃料,通過燃燒做功直接驅動發電機穩定發電。同時,機組還能高效回收發動機缸套水與高溫尾氣的余熱,用于供暖、生產蒸汽或制冷,實現“冷熱電三聯供”。將能源“吃干榨凈”,大幅提升綜合能效,做到能源循環高效利用。

　　One of the main applications of purified blast furnace gas is power generation. Among various power generation technologies, gas internal combustion engine power generation is favored by small and medium-sized steel enterprises due to its unique advantages. The gas internal combustion generator set is like a highly integrated "energy heart", using clean gas as fuel to directly drive the generator to generate stable electricity through combustion. At the same time, the unit can efficiently recover the waste heat from the engine cylinder liner water and high-temperature exhaust gas, which can be used for heating, steam production, or refrigeration, achieving the "combined cooling, heating, and power supply". Fully utilize energy resources, significantly improve overall energy efficiency, and achieve efficient energy recycling.

　　04展望：不止于電，未來更廣闊#

　　04 Outlook: Beyond electricity, the future is even broader#

　　將高爐煤氣轉化為電能,從來不止是一項技術革新,更象征著傳統重工業從“資源消耗型”向“資源循環型”的深度轉變。每一方煤氣的高效利用,都意味著一份能源的回收,一次碳排放的減少。

　　Converting blast furnace gas into electricity is not just a technological innovation, but also symbolizes the deep transformation of traditional heavy industry from a "resource consuming" to a "resource recycling" model. The efficient utilization of every coal gas means the recovery of energy and the reduction of carbon emissions.

　　當下,在中國從鋼鐵大國邁向鋼鐵強國的征程中,高爐煤氣發電等綠色低碳技術正扮演著至關重要的角色。中拓從未止步于單一的“變廢為寶”,而是致力于以技術創新為錨點,構建起“廢氣凈化-能源轉化-碳資產運營”的全鏈條服務體系,為企業提供從環保合規到價值提升的全生命周期解決方案,助力企業綠色升級增值增效。

　　Currently, in China's journey from a steel giant to a steel powerhouse, green and low-carbon technologies such as blast furnace gas power generation are playing a crucial role. Zhongtuo has never stopped at a single "turning waste into treasure", but is committed to building a full chain service system of "waste gas purification energy conversion carbon asset operation" with technological innovation as the anchor point, providing enterprises with full lifecycle solutions from environmental compliance to value enhancement, and helping enterprises achieve green upgrading, value-added and efficiency improvement.
