1、换热器设计采用AspenHFTS+进行设计，设计结果如下，并根据GB150-1998《钢制压力容器》和GB151-1998《管壳式换热器》对模拟的结果进行圆整和结构的设计。E0101AR0101A选择固定管板式换热器，管程通合成气，合成气主要组分含氢气、一氧化碳、二氧化碳，最高工作温度为700°C,壳程通烟气，主要成为二氧化碳和氮气，最高工作温度为400°Co壳程材料选择20g,列管材料选择0Crl9Ni9o列管排列采用正三角形排布，前端管箱为封头管箱，后端为与封头管箱相类似的固定管板式结构，壳体与列管温差较大，壳

2、体设计波形膨胀节，列管与管板的连接采用采用胀接。最后设计结果如下，型号为BEM2200-0.11-1345-4.5/25-1I。1234Size2150x4500SucMUnit(gro$$/eff/finned)Surf/Shell(gross/eff/finned)TypeBEM13455}12399.4I1345.5/1239.9fHorConnectedinShels/unit1010parallel1series5DesignPERFORMANCEOFONEUNIT6ShellSideTubeSideHe
