我公司承建的河北省承德环能热电有限责任公司#3、#4炉项目烟气净化系统提标改造工程于2025年08月22日通过72+24小时试运行。 The FGC system upgrading for Units #3 & #4 of Chengde Huanneng Thermal Power Co., Ltd. in Hebei Province—constructed by HEPT—has successfully passed the 72+24-hour full-load trial operation since 22nd.Aug 2025.
本次垃圾焚烧炉烟气脱硝系统项目提标改造范围为2×500t/d生活垃圾焚烧发电项目#4炉SCR低温脱硝系统（SGH+SCR）+催化剂和#3、#4炉小苏打干法脱酸系统（SDS）的设计、系统整合、制造、优化改造。其中包含#4炉引风机的设计、安装和改造。 The scope of this flue-gas denitration system upgrade for the waste incineration lines covers the design, system integration, fabrication and optimization of: a low-temperature SCR denitration system (SGH + SCR) + catalyst for Unit #4 of the 2×500 t/d waste-to-energy plant and a sodium-bicarbonate dry deacidification system (SDS) for Units #3 and #4. It also includes the design, installation and modification of the induced-draft fan for Unit #4.
在“72+24”小时不间断满负荷试运行阶段，此项目通过技改升级华星东方SCR低温脱硝系统展现出显著优势——通过提升120-180℃温区的反应活性，使氨逃逸率降低90%以上；配合催化剂成型工艺优化，增强催化剂孔隙均匀性及耐硫性，延长使用寿命，减少停机更换损失。其出口排放的NOx浓度稳定控制在35-45mg/Nm³（远低于50mg/Nm³设计标准），氨逃逸浓度低至0.1-0.8mg/Nm³（远低于8mg/Nm³限值），较传统系统降低40%以上蒸汽耗量，直接削减年度运行成本约350万元（蒸汽单价按120元/t）。 During the uninterrupted 72+24-hour full-load trial, the project demonstrated the striking advantages of HEPT’s upgraded low-temperature SCR denitration system: boosts activity in the 120–180 °C window and reduces NH₃ slip by over 90 %; optimized shaping gives the catalyst more uniform pores and better sulfur tolerance, extending service life and shortening outage time. NOx at the stack was steadily held at 35–45 mg/Nm³, well below the 50 mg/Nm³ design limit; NH₃ slip was as low as 0.1–0.8 mg/Nm³, far under the 8 mg/Nm³ cap; steam consumption dropped by more than 40 % compared with conventional systems, cutting annual operating costs by about CNY 3.5 million (steam priced at CNY 120/t). 这一成果源于华星东方二十余年深耕环保领域的技术积淀与低温脱硝系统创新突破：通过在引进三菱重工先进技术的基础上，历经数百次工况适配实验与十余代技术迭代，持续优化催化剂配方与反应器结构，最终开发出更契合中国复杂气候、多样燃料特性及严苛排放标准的低温脱硝解决方案。 This achievement stems from HEPT’s over twenty years of technical expertise in the environmental field and its breakthroughs in low-temperature denitration systems. Building on MHIEC’ advanced technology, the company has carried out hundreds of adaptation experiments and over ten generations of technical iterations, continuously optimizing catalyst formulations and reactor structures. The result is a low-temperature denitration solution better suited to China’s complex climate, diverse fuel characteristics and stringent emission standards. 当前研发团队正推进150℃超低温运行试验，探索催化剂在更宽温度窗口（120-180℃）的稳定性能，并配套开发智能氨水喷淋控制系统，通过前期设计流场模拟实现精确喷氨及氨分布，实现“精准喷射-高效转化-零逃逸”闭环控制，预计可进一步降低氨耗10%-15%。 The R&D team is now validating 150 °C ultra-low-temperature operation and developing an intelligent aqueous-ammonia spray control system. Up-front CFD modelling of the flow field will enable precise NH₃ injection and distribution, creating a closed loop of "accurate spraying–efficient conversion–zero slip", expected to cut ammonia consumption by a further 10–15 %. 该技改方案不仅解决了传统SCR系统“低温效率衰减、氨耗高、逃逸超标”三大行业难题，更构建了“设计-制造-运维”全链条成本优化模型。结合项目采用的国际领先炉排炉工艺与成熟烟气净化技术，实现了垃圾焚烧发电的“无害化处理+资源化利用”双重目标——通过焚烧发电将废弃物转化为电能，达成减量化与资源化；同时通过超低排放技术助力河北地区生态环境改善与空气质量提升，完美契合国家“双碳”战略与工业绿色转型需求，为客户创造“环保达标+经济降本”的双重价值。 This retrofit package not only solves the three industry pain points of conventional SCR—"low-temperature efficiency decay, high ammonia consumption, excessive slip"—but also builds a full-chain cost-optimization model covering design, manufacture and O&M. Coupled with the world-class grate furnace and proven gas-cleaning technologies adopted in the project, it achieves the dual goals of "harmless treatment + resource utilization" for waste-to-energy: waste is converted into electricity while emissions are kept ultra-low. The solution thus helps improve the ecological environment and air quality in Hebei, aligns perfectly with China’s "dual-carbon" strategy and green industrial transformation, and delivers the dual value of "compliance + cost reduction" for customers.
承德环能热电有限责任公司#3、#4烟气净化系统提标改造工程自2024年11月完成安装进入试运行阶段以来，已连续稳定运行超过一年，该项目采用我司选择性催化还原（SCR）工艺，配套华星东方引进优化的三菱重工低温催化剂，目前系统运行状态良好，工作温度、脱硝效率、氨逃逸等核心参数持续稳定达标，且具备持续稳定运行能力，验证了华星东方低温脱硝系统在低温工况下的可靠性与高效性。 Since the completion of installation and the commencement of trial operation in November 2024, the FGC system upgrade for Units #3 and #4 of Chengde Huanneng Thermal Power Co., Ltd. has been running continuously and stably for over one year. The project adopts HEPT’s selective catalytic reduction (SCR) process, equipped with introduced & optimized MHIEC’s low-temperature catalysts. At present, the system is in good operating condition, with core parameters such as working temperature, denitration efficiency, and ammonia slip remaining stable and compliant, demonstrating sustained and reliable operation. This outcome verifies the reliability and high efficiency of HEPT’s low-temperature denitration system under low-temperature working conditions.
