摘要
针对200 MW富氧燃烧示范项目开展典型方案设计研究和经济性比较分析,采用模拟计算和设计分析相结合的方式,研究确定了新建、兼容富氧燃烧干湿循环锅炉炉膛尺寸和热负荷指标,并完成脱硫、脱硝及烟风系统方案设计。针对空气燃烧、富氧燃烧干/湿循环兼容、富氧燃烧干/湿循环新建等5种方案从技术指标、投资和运行成本3个方面进行比较分析,获得了综合指标最佳的富氧燃烧技术方案。
Typical scheme research and economic analysis was carried out according to a 200 MW oxygen-enriched combustion demonstra-tion project. Using theoretical calculation and design analysis,the furnace dimensions and heat load indexes of new compatible oxygen-en-riched combustion boiler with drying and wetting cycle was determined. Meanwhile,desulfurization,denitration,air and flue gas system werealso designed. The technical indicators,investment and running cost of five schemes were compared,and the best comprehensive indexesoxygen-enriched combustion scheme was gained.
