我公司承建的河北省承德環(huán)能熱電有限責(zé)任公司#3、#4爐項目煙氣凈化系統(tǒng)提標(biāo)改造工程于2025年08月22日通過72+24小時試運行。
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.

本次垃圾焚燒爐煙氣脫硝系統(tǒng)項目提標(biāo)改造范圍為2×500t/d生活垃圾焚燒發(fā)電項目#4爐SCR低溫脫硝系統(tǒng)（SGH+SCR）+催化劑和#3、#4爐小蘇打干法脫酸系統(tǒng)（SDS）的設(shè)計、系統(tǒng)整合、制造、優(yōu)化改造。其中包含#4爐引風(fēng)機(jī)的設(shè)計、安裝和改造。
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”小時不間斷滿負(fù)荷試運行階段，此項目通過技改升級華星東方SCR低溫脫硝系統(tǒng)展現(xiàn)出顯著優(yōu)勢——通過提升120-180℃溫區(qū)的反應(yīng)活性，使氨逃逸率降低90%以上；配合催化劑成型工藝優(yōu)化，增強(qiáng)催化劑孔隙均勻性及耐硫性，延長使用壽命，減少停機(jī)更換損失。其出口排放的NOx濃度穩(wěn)定控制在35-45mg/Nm3（遠(yuǎn)低于50mg/Nm3設(shè)計標(biāo)準(zhǔn)），氨逃逸濃度低至0.1-0.8mg/Nm3（遠(yuǎn)低于8mg/Nm3限值），較傳統(tǒng)系統(tǒng)降低40%以上蒸汽耗量，直接削減年度運行成本約350萬元（蒸汽單價按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/Nm3, well below the 50 mg/Nm3 design limit; NH? 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).
這一成果源于華星東方二十余年深耕環(huán)保領(lǐng)域的技術(shù)積淀與低溫脫硝系統(tǒng)創(chuàng)新突破：通過在引進(jìn)三菱重工先進(jìn)技術(shù)的基礎(chǔ)上，歷經(jīng)數(shù)百次工況適配實驗與十余代技術(shù)迭代，持續(xù)優(yōu)化催化劑配方與反應(yīng)器結(jié)構(gòu)，最終開發(fā)出更契合中國復(fù)雜氣候、多樣燃料特性及嚴(yán)苛排放標(biāo)準(zhǔn)的低溫脫硝解決方案。
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.
當(dāng)前研發(fā)團(tuán)隊正推進(jìn)150℃超低溫運行試驗，探索催化劑在更寬溫度窗口（120-180℃）的穩(wěn)定性能，并配套開發(fā)智能氨水噴淋控制系統(tǒng)，通過前期設(shè)計流場模擬實現(xiàn)精確噴氨及氨分布，實現(xiàn)“精準(zhǔn)噴射-高效轉(zhuǎn)化-零逃逸”閉環(huán)控制，預(yù)計可進(jìn)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 %.
該技改方案不僅解決了傳統(tǒng)SCR系統(tǒng)“低溫效率衰減、氨耗高、逃逸超標(biāo)”三大行業(yè)難題，更構(gòu)建了“設(shè)計-制造-運維”全鏈條成本優(yōu)化模型。結(jié)合項目采用的國際領(lǐng)先爐排爐工藝與成熟煙氣凈化技術(shù)，實現(xiàn)了垃圾焚燒發(fā)電的“無害化處理+資源化利用”雙重目標(biāo)——通過焚燒發(fā)電將廢棄物轉(zhuǎn)化為電能，達(dá)成減量化與資源化；同時通過超低排放技術(shù)助力河北地區(qū)生態(tài)環(huán)境改善與空氣質(zhì)量提升，完美契合國家“雙碳”戰(zhàn)略與工業(yè)綠色轉(zhuǎn)型需求，為客戶創(chuàng)造“環(huán)保達(dá)標(biāo)+經(jīng)濟(jì)降本”的雙重價值。
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.

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.
