| This article introduces the working principle and parameters of the flue gas desulfurization. In view of the dry desulfurization transformation of Hanfeng Power Plant2×660MW unit, the advantages and disadvantages of various methods of desulfurization transformation are analysised and studied deeply. Then the paper introduces the reasons why Hanfeng Power Plant ultimatly makes the choice of the transformation scheme of Circulating Fluidized Bed Desulfurization (CFB-FGD). After transformation of the dry desulfurization, Hanfeng Power Plant makes the operation adjustment and technological transformation for the characteristics of dry desulfurization and the new problems encountered in operation in order to improve the economy and stability of the unit. Take a dry desulfurization, The social benefit, environmental benefit and economic benefit of Hanfeng Power Plant are improved significantly after taking the dry flue gas desulphurization. |
