Zhundong has large coal reserves and low mining costs, making it the most economical fuel in the Xinjiang Zhundong region. However, Zhundong coal has strong slagging and fouling properties, which seriously restricts the safe and stable operation of boilers. Boilers in the Zhundong region usually require burning at least 20% low alkali coal, the low reserves and high prices of low alkali coal seriously constrain the cost reduction of power plants. In order to promote cost reduction, an experimental study on burning high ratio of Zhundong high alkali coal was conducted on the 350 MW unit boiler of Wucaiwan Power Plant. A collaborative optimization strategy was adopted to prevent and control slag and contamination on the heating surface of the boiler. This included adding kaolin to coal to regulate the composition of coal ash, and deeply optimizing the operating parameters of the pulverization system, combustion system, and soot blowing system. The test results show that the collaborative optimization strategy has solved the long-standing problems of large-scale slag flow on the water-cooled wall, clogging of the burner nozzle, and severe fouling of the convective heating surface of this type of boiler. The safety and load capacity of the boiler operation have been greatly improved, and the coal structure can be lastingly maintained as 92.5% Zhundong high alkali coal and 7.5% kaolin, with significant safety and economic benefits.

准东煤储量大、开采成本低,是新疆准东地区最经济的动力煤种。但准东煤结渣、沾污性极强,严重制约锅炉安全稳定运行。准东地区锅炉通常需要掺烧20%以上低碱煤,而该地区低碱煤储量少、价格贵,发电厂降本增效受到严重制约。为了促进企业降本增效,在五彩湾电厂350 MW机组锅炉上开展了高比例燃用准东高碱煤试验研究。采用燃料燃烧全过程协同优化策略防控锅炉受热面结渣沾污,向煤中添加高岭土调控煤灰成分,对制粉系统、燃烧系统、吹灰系统的运行参数进行了深度优化。现场试验结果显示:协同优化策略解决了该型锅炉长期存在的水冷壁大面积流渣、燃烧器喷口结渣堵塞、对流受热面严重沾污的难题,锅炉运行安全性和带负荷能力大幅度提高,入炉煤结构可长期保持为92.5%准东高碱煤+7.5%高岭土,综合经济效益显著。

准东煤储量大、开采成本低,是新疆准东地区最经济的动力煤种。但准东煤结渣、沾污性极强,严重制约锅炉安全稳定运行。准东地区锅炉通常需要掺烧20%以上低碱煤,而该地区低碱煤储量少、价格贵,发电厂降本增效受到严重制约。为了促进企业降本增效,在五彩湾电厂350 MW机组锅炉上开展了高比例燃用准东高碱煤试验研究。采用燃料燃烧全过程协同优化策略防控锅炉受热面结渣沾污,向煤中添加高岭土调控煤灰成分,对制粉系统、燃烧系统、吹灰系统的运行参数进行了深度优化。现场试验结果显示:协同优化策略解决了该型锅炉长期存在的水冷壁大面积流渣、燃烧器喷口结渣堵塞、对流受热面严重沾污的难题,锅炉运行安全性和带负荷能力大幅度提高,入炉煤结构可长期保持为92.5%准东高碱煤+7.5%高岭土,综合经济效益显著。

Zhundong has large coal reserves and low mining costs, making it the most economical fuel in the Xinjiang Zhundong region. However, Zhundong coal has strong slagging and fouling properties, which seriously restricts the safe and stable operation of boilers. Boilers in the Zhundong region usually require burning at least 20% low alkali coal, the low reserves and high prices of low alkali coal seriously constrain the cost reduction of power plants. In order to promote cost reduction, an experimental study on burning high ratio of Zhundong high alkali coal was conducted on the 350 MW unit boiler of Wucaiwan Power Plant. A collaborative optimization strategy was adopted to prevent and control slag and contamination on the heating surface of the boiler. This included adding kaolin to coal to regulate the composition of coal ash, and deeply optimizing the operating parameters of the pulverization system, combustion system, and soot blowing system. The test results show that the collaborative optimization strategy has solved the long-standing problems of large-scale slag flow on the water-cooled wall, clogging of the burner nozzle, and severe fouling of the convective heating surface of this type of boiler. The safety and load capacity of the boiler operation have been greatly improved, and the coal structure can be lastingly maintained as 92.5% Zhundong high alkali coal and 7.5% kaolin, with significant safety and economic benefits.
