高效低NOx 煤粉燃烧器配套锅炉水冷壁改造∗

摘要

High efficiency and low-NOx pulverized coal combustion technologies have obvious advan-tages in energy efficiency and emission reduction. And using those technologies, boiler structure has great different requirements than traditional coal-fired industrial boilers. The promotion of this tech-nology needs to reconstruct traditional industrial boiler structure. Aimed at this problem, the plan for reconstruction was provided, and the solutions were theoretical arguments and experimental verifica-tion, and the results showed that reconstructed boiler performs well.%高效低NOx 煤粉燃烧技术在节能减排方面优势明显，采用该技术的燃烧器对锅炉结构要求较传统燃煤工业锅炉有较大不同，导致该技术的推广应用过程中需要对传统工业锅炉水冷壁结构进行改造。该文针对此问题提出了的工业锅炉水冷壁结构改造方案，并对方案进行理论论证和实验验证，结果表明改造后锅炉运行效果较好。
