循环流化床锅炉(Circulating Fluidized Bed Boiler, CFB锅炉)是一种高效清洁的燃烧技术设备,其核心原理是通过高速气流使燃料颗粒在炉膛内处于悬浮流动状态(即“流态化”),并利用气固分离器将未燃尽的颗粒回收至炉膛循环燃烧。其工作过程包含以下关键环节:
流态化燃烧
燃料(煤、生物质等)与惰性床料(如砂砾)混合后从炉膛底部送入,高压一次风从布风板喷入,使混合物形成类似流体的沸腾状态。燃料在850–900℃的低温燃烧环境下与空气充分混合燃烧,有效抑制氮氧化物(NOₓ)的生成。
颗粒循环系统
烟气携带未燃尽颗粒上升至炉膛出口,经旋风分离器进行气固分离。分离后的固体颗粒通过返料器重新注入炉膛底部,形成循环燃烧。此设计显著延长了燃料停留时间,使燃烧效率提升至95%以上,并适应高灰分、低热值的劣质燃料。
污染控制优势
炉内可直接添加石灰石等脱硫剂,与燃烧生成的二氧化硫(SO₂)发生反应实现原位脱硫,脱硫率可达90%。低温燃烧特性同时降低了热力型NOₓ的生成,无需额外脱硝装置即可满足环保排放标准。
工业应用场景
该技术广泛应用于燃煤电厂、城市垃圾焚烧、生物质发电等领域。例如中国自主研发的600MW超临界CFB锅炉,通过提高蒸汽参数(压力25.4MPa/温度571℃)进一步降低煤耗,成为高硫煤地区的主力机组。国际能源署(IEA)报告指出,CFB锅炉在燃用高水分褐煤时仍能保持稳定燃烧,其燃料灵活性显著优于传统煤粉炉。
