摘要
对上海锅炉厂有限公司600 MW等级低NOx排放超临界W火焰锅炉方案进行了简要介绍,主要包括锅炉的技术规范、总体布置、受压件设计、燃烧系统设计、空气预热器设计等。上海锅炉厂有限公司W火焰超临界锅炉的主要优势技术为低NOx排放,对于常用的无烟煤在不降低原有燃烧效率的基础上能够达到550 mg/Nm3的排放水平。同时在水冷系统设计中采用西门子公司的低质量流速垂直管技术,确保了水冷系统的安全。其他部分采用了已经运行业绩的成熟技术,所有这些设计确保了机组安全、高效和低排放。
The Shanghai Boiler Works Ltd. （SBWL） design of 600 MW arch fire supercritical boiler was introduced, which includes the technical specification, general arrangement, pressure part design, firing system design and air pre-heater design. The main advance of the design is the state-of-the-art advanced firing system technology, which can reach 550 mg/Nm^3 NO, emission without reducing the original firing efficiency. Besides, the SIEMENS low mass flux vertical waterwall technology was adopted also to ensure the safety and simplify the mechanical design of waterwall. Other proved technology and above technology contribute to the safety, high-efficiency and low NO. emission of the unit.
