日本东洋工程公司开发了以套管式转化炉管代替常规转化炉管的节能型制氢装置,达到了节减燃料消耗的目的。这种烃类蒸汽转化法制氢的节能型装置已经通过了工业化验证,可作为制氢、合成氨、甲醇等生产装置的组成部分。图1和图2分别示明常规型和节能型转化炉管的结构。节能型为套管式转化炉管,在内管和外管之间的环形空间内,下部1/3长
Japan’s Toyo Engineering Co., Ltd. has developed an energy-saving hydrogen plant that uses a bushing-type converter tube instead of a conventional converter tube to achieve the purpose of reducing fuel consumption. The energy-efficient plant for hydrogen production from hydrocarbon steam reforming has been industrialized and approved as part of hydrogen, ammonia, methanol and other production plants. Figures 1 and 2 illustrate the construction of a conventional and energy-saving reformer tube, respectively. Energy-saving bushing-type reformer tube, the inner tube and the outer tube between the annular space, the lower 1/3 long
