Time-averaged simulation of the furnace of a Chinese 135 MWe CFB boiler

Research output: Contribution to conference › Conference article › Scientific

Abstract

In the present study, two cases at different loads in the Chinese boiler are simulated and the results are compared to assess the capability of the time-averaged gas-solids CFD models to respond to changes in process conditions. The simulation results show a typical 3D voidage distribution in a CFB. Gas composition profiles show reasonable distributions of oxygen and combustion products inside the furnace. The difference between the two operational modes is at least qualitatively reproduced.
