State Analysis on the Main Components of Reformer Furnace Pipe Used for a Design Cycle

Abstract:

Comprehensive state analysis and life evaluation of the main components of reformer furnace run over service period by EPMA, microstructure and high temperature rupture property. The results show that element distribution and microstructure of reformer pipe, riser pipe, low collecting pipe and socket is normal and the remaining life is longer. The material of furnace pipe for the HK40 are able to meet the process requirement, but the wall thickness of reformer pipe is too large, affecting the thermal efficiency and the inner diameter is small to limit the catalyst and flow. It is good proposal to production enterprises that higher level of material such as ZG50Ni35Cr25NbM is selected to reduce the wall thickness properly, expand the diameter and improve efficiency. Similarly, it can also be appropriate for the riser pipe to choose a lower grade material and reduce the wall thickness and save cost.
