Tubular process furnaces are widely used especially in the chemical and petrochemical process plants and refineries. Retrofit of furnace is usually recommended for increasing plant capacity or improvement of the furnace (and/or plant) energy efficiency. A many different constraints of an existing furnace are the reasons from which the retrofit of a furnace is a very difficult task. At existing furnace the main operational and geometrical constraints are taken into account in furnace retrofit integration approach proposed by Z. Jegla et al. (2000a). This approach was developed primarily for improvement of the furnace energy efficiency. When furnace retrofit is performed for increasing the plant capacity additional criteria must be considered. The fluid hydrodynamic behaviour than plays an important role and influences the retrofit strategy. This problem is discussed in the paper and results in suggestion of the global conceptual algorithm for furnace retrofit strategy. Several practical case studies demonstrate applicability of proposed global furnace retrofit algorithm.
