通用的蒸汽转化装置由充满催化剂的许多管子组成 ,装在一矩形箱内 ,只作一般性密封 ,因此通常在稍低于常压的压力下操作 ,由位于热回收部分下游的烟道气吸入式鼓风机加以保持和控制。德国卡洛里克装置公司最近开发了一种新的密封型蒸汽转化装置 ,能使装置在 0 .0 5 MPa超压—— The common steam reforming unit consists of a number of tubes filled with catalyst packed in a rectangular box for general sealing only and is therefore operated normally at slightly lower atmospheric pressure and is drawn into the flue gas downstream of the heat recovery section Blowers to maintain and control. Germany Kallik equipment company recently developed a new sealed steam reforming device that enables the device at 0 0 5 MPa overpressure -
