Abstract: The 1. 0Mt/a reforming unit in Zhenhai Refining and Petrochemical Co. Ltd is the largest continuous reforming unit in China. It has special requirements on selection of furnace type, pipeline system, burner, waste heat recovery on convection interval and dew point corrosion prevention methods. The inlet temperature of coal economizer is leveled up in design to prevent dew point corrosioa Industrial application indicates that all furnace parameter designs are rational, they can meet the requirements of production, and the thermal efficiency of the whole furnace is up to 90. 4%.
