    • PURPOSE: A circulation fluidized bed boiler is provided to reduce corrosion generated in a heat exchanger tube of an external heat exchanger and accordingly to expand the life span of the heat exchanger tube. CONSTITUTION: A circulation fluidized bed boiler(1) is composed of a furnace(2) for burning fuel with fluidizing fuel together with a bed material(11); a cyclone(3) into which exhaust gas generated by burning in the furnace is introduced, for trapping particles contained in the exhaust gas; a detaching loop(13) into which the particles trapped by the cyclone is first introduced; and an external heat exchanger(6) for performing heat exchange between the particles. The inflow of corrosion factorial materials into the external heat exchanger is prevented by burning unburnt fuel in the particles by mounting the detaching loop.
    • 目的:提供循环流化床锅炉,以减少在外部热交换器的热交换器管中产生的腐蚀,从而延长热交换器管的寿命。 构成:循环流化床锅炉(1)由用于燃烧燃料和炉床材料(11)的流化燃料的炉(2)组成; 引入在炉内燃烧产生的废气的旋风分离器(3),用于捕集废气中所含的颗粒; 首先引入被旋风分离器捕获的颗粒的分离回路(13); 和用于在颗粒之间进行热交换的外部热交换器(6)。 通过安装分离环来防止腐蚀因素材料流入外部热交换器,这是通过在颗粒中燃烧未燃烧的燃料来防止的。
