08 Steam raising (boiler operation/design) compatible with the EU, Turow decided to, replace and upgrade six units (l-6) from 200 to 230 MW units and remove one unit 7. Units 8, 9 and 10 were equipped with dry sorbent desulfurization technology. Units 1 and 2 were replaced with new clean coal, circulating fluidized bed technology. These changes will make Turow, with six CFR units, the largest power station in the world based on fluidized bed technology.
Dynamic simulation of a circulating fluidized bed boiler of low circulating ratio with wide particle size distributions Lu, H. et al. Proc. Int. Conf Fluid. Bed Comhusr., 1999, 432440. This paper presents a steady state model of a coal fired CFB boiler considering the hydrodynamics, heat transfer and combustion. This model predicts the flue gas temperature, the chemical gas species (Oz, HaO, CO, COz and SOz) and char concentration distributions in both the axial and radial location along the furnace including the bottom and upper portion. To validate the model, it was compared to experimental data generated in a 35 t/h commercial CFB boiler with low circulating ratio.
