“…The traditional methods can accurately detect the status of the coke by detecting the unique frequency of the acoustic vibration signals generated by high pressure water impacting the drum wall during the process of removing coke [5,6]. Furthermore, Wang et al [7] found that the total energy spectrum distribution of vibration signals generated at the same height increased according to the fixed curve of the drum.…”

A distance and acoustic intensity reverberation (DAIR) physical model is developed that can be successfully applied to the signal processing of the hydraulic decoking process online monitoring. In this model, the transmission characteristics of acoustic signals generated by a moving sound source in a dynamic confined space are first analyzed using data recursion and correction according to the coordinate continuity in adjacent area and adjacent time. The results show that the nondetection zone of acoustic signals generated directly by the impact of water is eliminated, and the surface distribution of coke in the drum can be mapped in real time.
