The zone from 12 Furnace Outlet Plane (FOP) till RH section in upper furnace of super critical boiler has been modelled. 13 CFD analyses are carried out using Conjugate Heat Transfer (CHT) method by capturing transfer of 14 heat through metal walls, from flue gas to steam flowing inside selected RH tubes. The metal 15 temperature of these selected RH tube is predicted. Four cases have been studied covering 16 RH tube 16 assemblies and the pattern of metal temperature distribution on selected RH tube walls is predicted. 17 Three dimensional surfaces of wall temperature verses tube length for each of the RH tubes in 16 18 assemblies have been plotted which will help the designer in identifying likely zones of RH tube rupture 19 at power plant sites. Commercial tools Gambit, Icem Cfd and Ansys Fluent have been used for carrying 20 out the CFD analyses and plotting tool Gnu Octave has been used to generate three dimensional surface 21 plots. 22
