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

Research output: Contribution to conferenceConference articleScientific

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.
