Abstract
The sensitivity of a homogeneous equilibrium model devised to predict the steady state performance of a fluidized bed straw gasifier was tested for different parameters. Bed temperature proved sensitive to changes in fuel distribution function, nitrogen-oxygen ratio, solid circulation coefficient, fluidization velocity, bed height, and equivalence ratio. The higher heating value and composition of produced gas were influenced only by the N-O ratio and the equivalence ratio. The fluidization velocity, N-O ratio, and equivalence ratio affected normalized gas production.
