Abstract: In the current scenario energy demand plays a major role for which biomass technology meets global target on renewable energy. In which boilers performance evaluation is more essential. The major objective of this work is to evaluate the turbulent air flow distribution in wind box channel of travelling grade stoker boiler. In order to improve the optimum performance of the boiler used in the biomass power plant, the air should uniformly distributed to the burner. In this paper the sever turbulent flow and high pressure zones are generated by examining the recirculation flow at several locations in wind box channel. Due to these process the unequal air flow exits at exit valve. Computational fluid dynamics (CFD) modelling is the simulation tool used to determine the high pressures zones and turbulent flow of wind box segment. The results indicates that the design of wind box segment and combustion is more effective in increasing the performance of boiler and the amount velocity of air flow is decreased from around 30%. Increasing amount of the additive from around 90% of O2 level, and 80% of CO2 level and there by temperature distribution in combustion bed is grown upto 40%.
