有个老外的工艺包里面规定高压加热炉的对流段不允许加热 ...? the absorbed duty specified is the radiant heat energy absorbed by the process fluid only. no process coils are allowed in the convection section. steam generation, steam superheat, and/or air preheat are not included and shall be determined during detailed design. 吸收的负荷(热量)只是工艺流体在辐射的热量吸收。没有工艺盘管在对流区。不包含蒸汽发生器、过热器、空气加热器。决定在详设中。 没说“对流段不允许加热物料”。这是辐射段的描述和对辐射段的要求。查看更多
