1、摘要管式加热炉是一种火力加热设备，它利用燃料在炉膛内燃烧时产生的高温火焰与烟气作为热源，加热在炉管中高速流动的介质，使其达到工艺规定的温度，以供给介质在进行分馏、裂解或反应等加工过程中所需要的热量，保证生产正常进行。本设计为年产200万吨原油圆筒管式加热炉，在本设计中主要完成对辐射段、对流段以及烟道的工艺尺寸的计算、热量的衡算、钢结构的计算及校核和加热炉各零部件的选用。其中辐射室工艺尺寸包括辐射室炉管的直径、炉管的壁厚、炉管的长度、炉管的根数、辐射室的外形尺寸等；对流室的工艺尺寸包括对流炉管的形式、炉管的直径、炉管的壁厚、炉管的排数及
2、每排的根数、热量衡算的部分包括计算燃料量、燃烧器的规格和根数。本设计的要点是加热炉高的热效率，提高燃油的利用率。常采用的措施有降低炉子的排烟温度、减小过热空气系数、减少化学部完全燃烧损失、减少机械不完全燃烧损失、减少炉壁散热等。也可以设置烟气余热回收系统来提高加热炉的热效率。关键字：加热炉；钢结构；炉管；辐射；对流；AbstractTubular-furnaceheatingequipmentisakindoffirepower,whichtheuseoffuelcombustioninthefurnacewhentheflamean
