Dynamic modeling of the flue gas side of large-scale circulating fluidized bed boilers
Paper i proceeding, 2021

This paper presents a 1.5D dynamic model of the gas side of large-scale circulating fluidized bed boilers. The model accounts for the solid’s hydrodynamics, the fuel conversion and the heat transfer to the waterwalls. The model is validated with industrial data from a 100 MWth unit, showing a good agreement between simulation results and measured data. The validated model is used to study the dynamics of the furnace after a load change is introduced. Simulation results show that regions with large concentration of solids are slower to reach steady-state but are less sensitive to load changes.
