Abstract: The reactor feed furnace is one of the essential equipment in hydrotreating units, operating under ?severe conditions? and handling ?multiple operating modes?. The flow regime, inner film temperature, tube wall temperature, flux density are key parameters within furnace-front hydrogen mixing reaction furnace tubes?. In recent years, multiple accidents of radiation tube rupture have occurred in reaction furnaces. Based on a case study of an enterprise in western China, this paper briefly analyzes the causes of tube rupture and provides several suggestions for safe operation.
Key words: reactor, furnace tube rupture, flow regime, inner film temperature
