The bubbling fluidized bed gasifier is the one most important technology of the gasification through which biomass fuel like Municipal Solid Waste (MSW) is incompletely burnt in the presence of air and then converted into high calorific value gases fuel. The capabilities of bubbling fluidized bed gasifier are affected by feedstocks characteristics, process parameters and design parameters. CFD simulation have been done for improvement of process parameters for Municipal Solid Waste and Sugarcane Bagasse. CFD simulations are carried for a cylinder-shaped bubbling fluidized bed with a static bed height of 0.665m with 0.144m diameter of rector chamber and 1.46m reactor height. The gas-solid hydrodynamics and gasification process inside a fluidized-bed biomass gasifier are calculated using the CFD solver ANSYS-FLUENT 20.0. A 2-D rectangular model based on Eulerian-Eulerian approach attached with granular kinetic theory has been established to simulate the bed hydrodynamics for the BFBG where volume fraction, bed pressure drops and velocities has been focused using ANSYS Fluent software. The effects of particle properties, gas velocity and temperature of bed material within the reactor has been examined approximately for simulation which provides a significant basis for detailed design of BFBG.
