技术介绍
辐射式废热锅炉是能源化工行业显热回收关键设备,被广泛运用于合成气化与废热回收系统中。在煤气化系统中,辐射式废热锅炉通常与气化炉直接连接,气化炉合成气化后的产物,通常是高温并带还原性或氧化性气氛的合成气,其温度通常高于1000℃以上,通过辐射式废热锅炉对合成气的这部分高温显热进行回收,可有效提高系统热效率,有利于全系统的节能减耗。现有技术的辐射式废热锅炉通常为多级圆筒形废炉串联连通而形成,具体包括壳体和套设在壳体内的若干串联排布的筒状水冷壁,从气化炉出来的高温气体从水冷壁顶部的合成气进口进入至水冷壁的内腔中,然后沿着水冷壁的内腔一直向下流走,最终从辐射式废热锅炉底端的合成气出口流出,水冷壁通过热交换吸收这些高温气体中的热量,从而使得高温气体的温度降低。由于现有技术的辐射式废热锅炉的水冷壁为一层,即,其所形成的气体冷却通道为一单向直流通道,因此,若需要将高温气体的温度降低到一定值,则需要设置较长的水冷壁内件,这会导致套设在水冷壁外侧的壳体随之增高,使得材料消耗增加,且整个设备占用 ...
