Existing complicated and complex calculation procedures for design of process tubular furnaces create main reason from which the connection of targeting and detail design stage of furnace (i.e. continuous design and/or retrofit approach) is a serious problem in design practice. A complex newly developed approach of furnaces design and/or retrofit is presented in this paper. This comprehensive approach involves application of heat transfer (radiation and convection) in equipment design, thermodynamic analysis for process design from the point of view of furnace integration, and last but not least the latest approach consisting in involving process fluid flow and hydrodynamic analysis to avoid potential troubles in operation. This new methodology bridges existing gaps between modern targeting methods based on Pinch Analysis (providing us with optimised parameters like temperature of preheated air, stack temperature, excess air etc.) and detailed design of furnaces. It is partly interactive and is based on three stages of design: (i) targeting, (ii) synthesis and (iii) detailed design. It can be applied for both grassroots and retrofits problems.
