| Abstract: | Based on the enlargement of fine particles by heterogeneous condensation,removal of particles from LIFAC(Limestone Injection into the Furnace and Activation of Calcium) desulfurization system was investigated experimentally.Supersaturation required for fine particles growth was achieved by adding adequate steam to the wet flue gas at the inlet of condensation chamber.The enlarged dusty droplets were removed by a high efficiency demister.The particle number concentration,size distribution,temperature and hum... |
