焦化气发电机组：盘活焦化废弃气源，年创产值超百亿，传统煤化工循环转型核心装备

　　Coking gas generator set: Activate coking waste gas source, annual output value exceeds 10 billion yuan, core equipment for traditional coal chemical cycle transformation

　　传统煤化工行业长期陷入两大困局：焦化生产过程中产生的大量焦炉煤气，要么直接排空燃烧，要么仅作简易热源利用，优质可燃气源白白浪费，既造成巨额能源损耗，又带来环保与碳排放压力；单一焦化生产利润微薄，产业链短、附加值低，高碳排属性更不符合双碳政策要求。而贵州水城总投资200亿的煤-焦-化-电一体化项目，凭借**焦化气发电机组**实现破局，将焦化副产煤气、氢气等废弃气源高效转化为清洁电能，搭配热电循环耦合，真正做到一块煤“吃干榨尽”，不仅让焦化废气变废为宝，更带动项目年总产值突破100亿，成为传统煤化工绿色循环、降本增效的标杆方案。

　　The traditional coal chemical industry has long been trapped in two major dilemmas: the large amount of coke oven gas generated during coking production is either directly discharged for combustion or only used as a simple heat source, resulting in the waste of high-quality combustible gas sources, causing huge energy losses and environmental and carbon emission pressures; Single coking production has meager profits, a short industrial chain, low added value, and high carbon emission attributes that do not meet the requirements of the dual carbon policy. The coal coke chemical electricity integration project in Shuicheng, Guizhou, with a total investment of 20 billion yuan, has achieved breakthrough through the use of coking gas generator units. It efficiently converts waste gas sources such as coking by-product gas and hydrogen into clean electricity, coupled with thermal electric cycles, truly achieving the goal of "eating dry and squeezing out" a piece of coal. This not only turns coking waste gas into treasure, but also drives the annual total output value of the project to exceed 10 billion yuan, becoming a benchmark solution for traditional coal chemical green circulation, cost reduction and efficiency improvement.

　　焦化气藏巨能，废弃气源成发电黄金燃料

　　Coking gas reservoir has tremendous energy, and waste gas sources are used as gold fuel for power generation

　　焦炉煤气是煤焦化过程中的必然副产物，属于高热值可燃气体，富含甲烷、氢气等可燃成分，是绝佳的发电燃料，却长期被行业忽视。传统焦化厂仅将其作为辅助热源，大量富余煤气直接放空燃烧，不仅浪费能源，还增加碳排放，每万吨焦炭副产的焦炉煤气，若直接浪费，相当于损失数万度电能与巨额经济收益。

　　Coke oven gas is an inevitable byproduct of coal coking process, belonging to high calorific value combustible gas, rich in combustible components such as methane and hydrogen, and is an excellent fuel for power generation, but it has long been overlooked by the industry. Traditional coking plants only use it as an auxiliary heat source, and a large amount of surplus gas is directly vented and burned, which not only wastes energy but also increases carbon emissions. If every 10000 tons of coke by-product coke oven gas is directly wasted, it is equivalent to losing tens of thousands of kilowatt hours of electricity and huge economic benefits.

　　焦化气发电机组专为焦化行业气源特性定制，可高效适配焦炉煤气、灰氢等混合燃料，无需复杂改造，仅需配套简易净化预处理设备，即可将废弃气源稳定转化为电能，彻底改变“焦化只产焦炭、废气白白浪费”的传统模式。贵州水城项目中，焦化环节产生的富余煤气、衍生灰氢，直接就近供给焦化气发电机组发电，电厂产生的蒸汽又回供焦化生产，一墙之隔实现能源双向循环，不让任何一份能量空转，最大化挖掘焦化气源价值。

　　The coking gas generator set is specially customized for the gas source characteristics of the coking industry, and can efficiently adapt to mixed fuels such as coke oven gas and ash hydrogen. It does not require complex modifications and only needs to be equipped with simple purification and pretreatment equipment to stably convert the waste gas source into electrical energy, completely changing the traditional mode of "coking only produces coke and waste gas". In the Guizhou Shuicheng project, the surplus coal gas and derived ash hydrogen generated in the coking process are directly supplied to nearby coking gas generators for power generation. The steam generated by the power plant is then returned to coking production, achieving a two-way energy cycle separated by a wall, preventing any energy from idling and maximizing the value of coking gas sources.

　　循环耦合发力，产业链价值翻倍增长

　　Circular coupling drives growth, doubling the value of the industrial chain

　　焦化气发电机组的核心价值，不仅在于发电创收，更在于打通煤化工循环产业链，实现“焦化-发电-新能源”一体化协同。贵州水城项目布局2×66万千瓦燃煤发电、200万吨煤焦化、264万千瓦新能源三大板块，焦化气发电机组作为核心纽带，将焦化副产废气全部资源化利用，去年焦化项目试运营即产出焦炭56万吨，产值近10亿，配套发电系统同步运行，形成“废气发电、蒸汽回供、多品产出”的闭环模式。

　　The core value of coking gas power generation units lies not only in generating revenue, but also in connecting the coal chemical cycle industry chain and achieving integrated synergy of "coking power generation new energy". The Guizhou Shuicheng project layout consists of three major sectors: 2 × 660000 kW coal-fired power generation, 2 million tons of coal coking, and 2.64 million kW of new energy. The coking gas generator set serves as the core link, utilizing all coking by-products and waste gas as resources. Last year, the coking project produced 560000 tons of coke during trial operation, with a production value of nearly 1 billion yuan. The supporting power generation system operates synchronously, forming a closed-loop model of "waste gas power generation, steam supply, and multi product output".

　　相较于单一焦化生产，配套焦化气发电机组后，项目不再区分主副产物，从单一焦炭产出，延伸至焦炭、煤焦油、电力、蒸汽等20余种产品，每一份气源、每一份余热都得到充分利用，彻底告别能源浪费。机组运行稳定，适配焦化生产连续作业工况，发电既可满足焦化厂自身生产、设备运转用电需求，实现用电自给自足，省去大额外购电费，多余电量还可并入电网，额外创造发电收益，大幅提升项目整体盈利能力。

　　Compared to single coking production, with the installation of coking gas generator units, the project no longer distinguishes between main and by-products. It extends from single coke production to more than 20 products such as coke, coal tar, electricity, steam, etc. Every gas source and waste heat is fully utilized, completely bidding farewell to energy waste. The unit operates stably and is suitable for continuous operation in coking production. Its power generation can meet the electricity needs of the coking plant's own production and equipment operation, achieving self-sufficiency in electricity consumption and saving large external electricity costs. The excess electricity can also be integrated into the power grid, creating additional power generation revenue and significantly improving the overall profitability of the project.

　　降碳减污增效，传统能源存量优化最优解

　　Reducing carbon emissions, reducing pollution, and increasing efficiency, optimizing the optimal solution for traditional energy storage

　　在双碳目标下，传统煤化工并非只能一刀切关停，存量优化、循环利用才是更贴合现实的转型路径，而焦化气发电机组正是核心支撑。通过将原本排空的焦化气回收发电，替代直接燃烧排空，大幅降低项目碳排放强度，同时搭配灰氢掺烧技术，进一步减污降碳，提升机组调峰能力，让高碳煤化工实现低碳化运行。

　　Under the dual carbon goal, traditional coal chemical industry cannot be shut down in a one size fits all manner. Optimizing inventory and recycling are more realistic transformation paths, and coking gas generator units are the core support. By recycling the originally emptied coking gas for power generation, replacing direct combustion and emptying, the carbon emission intensity of the project is significantly reduced. At the same time, combined with ash hydrogen co firing technology, further pollution reduction and carbon reduction are achieved, and the peak shaving capacity of the unit is improved, enabling low-carbon operation of high carbon coal chemical industry.

　　贵州水城项目通过焦化气发电与产业链耦合，把一块煤的碳排强度降至最低，既保留了传统能源的产业价值，又实现绿色低碳转型，还带动数千个就业岗位，拉动物流、服务等上下游产业发展，实现环保、经济、社会效益三丰收。对比传统煤化工模式，配套焦化气发电机组后，企业能耗成本直降，环保合规压力大幅缓解，无需承担废气浪费带来的环保处罚，投资回报率显著提升。

　　The Guizhou Shuicheng project couples coking gas power generation with the industrial chain to minimize the carbon emission intensity of a single piece of coal, retaining the industrial value of traditional energy while achieving green and low-carbon transformation. It also drives thousands of job opportunities, stimulates the development of upstream and downstream industries such as logistics and services, and achieves three harvests of environmental protection, economic, and social benefits. Compared with the traditional coal chemical industry model, with the installation of coking gas generator units, the energy consumption cost of enterprises has been directly reduced, and the pressure of environmental compliance has been greatly alleviated. There is no need to bear the environmental penalties caused by waste gas, and the return on investment has been significantly improved.

　　煤化工转型刚需，循环经济核心装备

　　The transformation of coal chemical industry is urgently needed, and the core equipment of circular economy is essential

　　在可再生能源完全替代化石能源之前，焦化气发电机组为传统煤化工转型指明方向，它不是颠覆性技术，却是产业链循环的关键纽带，能将废弃能源转化为核心收益，让单一生产转向多元增值，让高碳排放转向低碳利用。对于焦化企业而言，布局焦化气发电机组，就是打通循环经济最后一环，实现“一块煤吃干榨尽”，在降本、增效、减碳的同时，助力企业完成绿色转型，适配当下产业政策与市场需求，成为传统煤化工高质量发展的必备核心装备。

　　Before renewable energy completely replaces fossil fuels, coking gas power generation units point the way for the transformation of traditional coal chemical industry. It is not a disruptive technology, but a key link in the industrial chain cycle. It can convert waste energy into core income, shift single production to diversified value-added, and shift high carbon emissions to low-carbon utilization. For coking enterprises, the layout of coking gas power generation units is to open up the last link of circular economy, achieve "one piece of coal to eat and squeeze", help enterprises complete green transformation while reducing costs, increasing efficiency, and reducing carbon emissions, adapt to current industrial policies and market demand, and become an essential core equipment for the high-quality development of traditional coal chemical industry.
