本次垃圾点火炉烟气脱硝系统项目提标刷新领域为2×500t/d生涯垃圾点火发电项目#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、、制作、、优化刷新。 。其中蕴含#4炉引风机的设计、、装置和刷新。 。 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伟德国际官网东方SCR低温脱硝系统展示出显著优势——通过提升120-180℃温区的反映活性，使氨逃逸率降低90%以上；；；共同催化剂成型工艺优化，加强催化剂孔隙均匀性及耐硫性，耽搁使用寿命，削减；；；凰鹗。 。其出口排放的NOx浓度不变节制在35-45mg/Nm?（远低于50mg/Nm?设计尺度），氨逃逸浓度低至0.1-0.8mg/Nm?（远低于8mg/Nm?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 NH? 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/Nm?, well below the 50 mg/Nm? design limit; NH? slip was as low as 0.1–0.8 mg/Nm?, far under the 8 mg/Nm? 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). 这一成就源于伟德国际官网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尝试与十余代技术迭代，持续优化催化剂配方与反映器结构，最终开发出更符合中国复杂气象、、多样燃料个性及严苛排放尺度的低温脱硝解决规划。 。 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. 当前研发团队正推动150℃超低温运行试验，索求催化剂在更宽温度窗口（120-180℃）的不变机能，并配套开发智能氨水喷淋节制系统，通过前期设计流场仿照实现精确喷氨及氨散布，实现“精准喷射-高效转化-零逃逸”闭环节制，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 NH? injection and distribution, creating a closed loop of "accurate spraying–efficient conversion–zero slip", expected to cut ammonia consumption by a further 10–15 %. 该技改规划不仅解决了传统SCR系统“低温效能衰减、、氨耗高、、逃逸超标”三大行业难题，更构建了“设计-制作-运维”全链条成本优化模型。 。结合项目选取的国际当先炉排炉工艺与成熟烟气净化技术，实现了垃圾点火发电的“无害化处置+资源化利用”双重指标——通过点火发电将拔除物转化为电能，达成减量化与资源化；；；同时通过超低排放技术助力河北地域生态环境改善与空气质量提升，美满符合国度“双碳”战术与工业绿色转型需要，为客户创制“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.
运城环能热电有限责任公司#3、、#4烟气净化系统提标刷新工程自2024年11月实现装置进入试运行阶段以来，已陆续不变运行超过一年，该项目选取我司选择性催化还原（SCR）工艺，配套伟德国际官网东方引进优化的三菱重工低温催化剂，目前系统运行状态优良，工作温度、、脱硝效能、、氨逃逸等主题参数持续不变达标，且具备持续不变运行能力，验证了伟德国际官网东方低温脱硝系统在低温工况下的靠得住性与高效性。 。 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.
