Dry Flue Gas Desulfurization Technologies for Pulverized Coal Fired Boilers

  • Recent years have seen an increase worldwide in the awareness of environmental protection, while its dramatic growth is forecast as well. Such predictions highlight the importance of reducing the impact of pollutants, contaminating air, water, and soil. An area of particular importance regards the potentials for acid rain formation due to the emission of sulfur dioxide and nitrogen oxides during the combustion of fossil fuels. Particularly notable are the programs of flue gas desulfurization that have been carried out in power plants worldwide for decades now and also in our country in recent years. Dry flue gas desulfurization technologies for pulverized coal fired boilers are described in this paper, such as: furnace direct sorbent injection, duct sorbent injection, application of activation reactor and lime spray drying process. In addition, the economic aspects and the efficiency of sulfur dioxide emission reduction are specially considered in the paper. The choice of desulfurization method is often based on the comparison of costs associated with the application of a particular method. There fore, for the technologies described, the average emission reduction costs are presented and the most effective methods are highlighted.
