Abstract: In this thesis the steam flow in steam boiler tubes is modeled using PRO-E design software. The thesis will focus on thermal and CFD analysis with different velocities (25, 30, 35& 40m/s).Thermal analysis done for the steam boiler by steel, stainless steel& brass at different heat transfer coefficient values. These values are taken from CFD analysis at different velocities. In this thesis the CFD analysis to determine the heat transfer coefficient, heat transfer rate, mass flow rate, pressure drop and thermal analysis to determine the temperature distribution, heat flux with different materials. 3D modeled in parametric software Pro-Engineer and analysis done in ANSYS.

Keywords: Finite element analysis, steam boiler, CFD analysis, thermal analysis.
