CONVECTION SECTION FAILURE ANALYSIS AND FITNESS-FOR-SERVICE ASSESSMENT

摘要

In-service equipment failures present a considerable challenge to reliability engineers. Since these events are unplanned, the spare parts and resources to quickly and efficiently make repairs may not be readily available. Facility management is faced with decisions to perform short-term repairs to equipment to safely operate until repair parts, equipment, manpower and product supply permit an extended outage and long-term repair. In these instances, the reliability engineer will need to answer many questions, but in the case of a failure of convection tubes in a furnace (as presented in this article), they will need to answer whether the facility can restart the furnace and continue to operate reliably until the next planned shutdown.
