Study on Combustion Performances of Burners in Furnace in Coal Fired Power Plants

Steam generation are one of the critical components of a thermal powerplant. Studies of the performance of combustion in a steam generator are very complex in nature. In this work numerical simulations are used to investigate the characteristics of gas and coal particle two-phase flow in boiler furnaces. In order to examine the detailed behavior of the flow different load conditions were given with varying the velocity of flow of air and fuel. Flow characteristics with multiple number of burners and firing at different locations resembeling variation of load is studied. Studies of effect of different operating conditions are studied using commercial code FLUENT. To determine velocity, temperature characteristics a 3D combustor model isused in this case study. Change of size in burners is done in order to find the temperature profiles changes in furnace. Analyses of particle trajectories are done so as to study the emission characteristics, fouling on burners etc.
