焦炉煤气发电机组：唤醒“工业尾气”，驱动绿色未来

　　Coke oven gas generator set: awakening "industrial exhaust gas" and driving a green future

　　在钢铁厂的巨型高炉旁,除了炽热的铁水,还有一股看不见的庞大能量在持续不断地产生-焦炉煤气。过去,焦炉煤气被视作废气直接排放或焚烧,既造成能源浪费,也加重环保负担。如今,借助先进的技术,昔日的工业尾气正被高效回收,转化为驱动生产的绿色电能。今天,就让我们一起揭开焦炉煤气发电的神秘面纱。

　　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 producing coke oven gas. In the past, coke oven gas was treated as waste gas and directly discharged or burned, 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 coke oven gas power generation together.

　　01焦炉煤气：从“必然副产”到“城市能源”#

　　01 Coke oven gas: from "inevitable byproduct" to "urban energy"#

　　焦炉煤气并非特意制造,而是高炉炼铁过程中自然生成的副产物。当焦炭和煤粉在千度高温下还原铁矿石时,会产生大量以一氧化碳（CO）和氢气（H?）为主的可燃气体,也就是焦炉煤气 。然而,它天生“体质特殊”：热值低（约为天然气的十分之一）,成分复杂（含有粉尘、硫化物等杂质）。但其产量极为可观,每生产1吨铁水,大约会产生1500-2000立方米的焦炉煤气。作为钢铁大国,我国焦炉煤气年产生量高达数千亿立方米,正因如此,它被称作“未被看见的能源宝藏”。

　　Coke oven 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 coke oven 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, with approximately 1500-2000 cubic meters of coke oven gas produced for every ton of molten iron produced. As a major steel producing country, China's annual production of coke oven gas reaches hundreds of billions of cubic meters, which is why it is known as the 'unseen energy treasure'.

　　过去焦炉煤气是棘手废气,现在它是绿色能源。随着技术和理念的升级,焦炉煤气高效回收已成为钢铁企业实现循环经济的关键一环,其回收利用率甚至成为衡量企业绿色发展水平的重要指标。

　　In the past, coke oven gas was a tricky waste gas, but now it is a green energy source. With the upgrading of technology and concepts, efficient recovery of coke oven 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净化：从“粗犷”到“精制”的必经之路

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

　　如同矿石需要冶炼才能成材,刚出炉的焦炉煤气也必须经过严格的净化“洗礼”,才能成为发电设备的优质“食粮”。煤气净化主要包括脱硫、除尘、除焦等关键环节,目的是要确保气体的安全性与清洁度。

　　Just as ore needs to be refined to become material, freshly produced coke oven 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.

　　经过高效净化,煤气中的粉尘、焦油、硫化物等有害物质被大幅去除,氧气含量严格控制在安全范围内,气体既洁净又安全,为后续发电系统的高效转化和稳定运行奠定了基础。

　　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发电：将气体转化为光与热#

　　03 Power Generation: Converting Gas into Light and Heat#

　　净化后的焦炉煤气,最主要的应用方向之一就是发电。在众多发电技术中,燃气内燃机发电因其独特的优势,受到中小型钢铁企业的青睐。燃气内燃式发电机组就像一套高度集成的“能源心脏”,将清洁煤气作为燃料,通过燃烧做功直接驱动发电机稳定发电。同时,机组还能高效回收发动机缸套水与高温尾气的余热,用于供暖、生产蒸汽或制冷,实现“冷热电三联供”。将能源“吃干榨净”,大幅提升综合能效,做到能源循环高效利用。

　　One of the main applications of purified coke oven 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：不止于电，未来更广阔#

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

　　将焦炉煤气转化为电能,从来不止是一项技术革新,更象征着传统重工业从“资源消耗型”向“资源循环型”的深度转变。每一方煤气的高效利用,都意味着一份能源的回收,一次碳排放的减少。

　　Converting coke oven 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.
