全燃高炉煤气锅炉炉内燃烧过程的数值模拟

摘要

以鞍钢股份公司220t/h全燃高炉煤气锅炉为研究对象,利用CFD软件,对全燃高炉煤气锅炉炉内的燃烧过程进行模拟.得出锅炉炉内的速度场、温度场及NO,的排放量;并分析缩腰形炉膛及对冲布置的燃烧器对炉内燃烧过程的影响.模拟结果可为同类锅炉的优化设计、合理运行提供理论指导.%A 220 t / h BFG fired boiler of Angang Steel Company Limited is researched by using CFD software to simulate the combustion process of BFG fired boiler.The velocity field and temperature field is obtained, furthermore the influence that waist shape furnace and opposed layout combustor impact on the combustion process in furnace.And a theoretical guidance is provided to optimal design and reasonable operation of similar boiler.
