Abstract: Heavy industrialization & modernization of society demands in increasing of power cause to research & develop new technology & efficient utilization of existing power units. Variety of sources are available for power generation such as conventional sources like thermal, hydro, nuclear and renewable sources like wind, tidal, biomass, geothermal & solar. Out of these most common & economical way for producing the power, is by thermal power stations. Various industrial boilers plays an important role to complete the power generation cycle such as CFBC (Circulating Fluidized Bed Combustion), FBC (Fluidized Bed Combustion), AFBC (Atmospheric Fluidized Bed Combustion Boiler), CO Boiler, RG & WHR Boiler (Waster heat recovery Boiler). This paper is intended to comprehensively give an account of knowledge related to refractory & its failure in CFBC boiler with due effect of flue gas flow during operation on refractory by using latest technology of CAD (Computer aided Design) & CAE (Computer aided Engineering). By conceptual application of these technology the full scale model is able to analyze in regards the flow of flue gas & bed material flow inside the CFBC loop via CFD (Computational Fluid Dynamics) software. The results obtained are helpful to understand the impact of gas & particles on refractory in different areas & also helped to choose suitable refractory material in different regions.
