Abstract
Steam gasification is a well-known technology, which is used to produce a high
quality product of gas, especially for power generation applications. The gas
composition, gas quality and the purity has a great role to play depending on the
end application. Hence the bio mass steam gasification process was studied using
the Computational Particle Fluid Dynamics (CPFD) simulation tool, ‘Barracuda
VRTM’. The software is well suited for simulating dense particle laden fluids
due to its numerical solving methods for both the particles and the fluid.
B oth the experiments and simulations were carried out for a cylindrical
isothermal fluidized bed reactor without chemistry, to compare the deviations of
simulation results from the experimental results. The simulation results were
agreed with the experimental results and they confirmed the same minimum
fluidization velocity.
Three dimensional simulations were carried out for a cylindrical geometry to
study energy, and momentum transport within a simplified dual fluidized bed
steam gasification reactor and the important chemistry were included. According
to the simulation results, the product gas mainly consisted of CO and the amount
of H2 was less in comparison to the higher amounts of CH4.The cumulative
production of combustible gasses (CO, CH4 and H2) was estimated as
280 Sm3/day based on the simulation results.
