Abstract — In present investigation numerical analysis is performed in CFB boiler tube with different mass flow rate, the observed value of exit temperature of water is compared with numerical model developed in CFD with optimization in CFB boiler tube fin profile pattern i.e. rounded wedge, perforated square and wedge shaped fin to predict effective temperature distribution further, In a Computational Fluid Dynamics (CFD), the trial has been conducted on the temperature, for a boiler water tube. In the CFD investigation it was assumed that, the flow of water is along length of tube. This investigation was carried out on a mass flow rate of 5, 10, 20, 30 kg/s.
