Numerical Simulation of Gas Flow in a 48 t/h Biomass Fired Grate Boiler with Inner Dust Removal Device
This paper presents the numerical simulation of a 48t/h biomass fired grate boiler with an inner boiler dust removal device located in the third pass. The results show that the inner dust removal device can correct the decline of the gas flow in the passes effectively on the basis of dust separation. The best air flow ratio of RPA: RSA: RIA is = 4: 4: 2 correspondingly. Therefore, the new inner dust removal device should be applied in current commercial biomass boilers to improve their operation performance.
