摘要
某600MW燃煤机组石灰石-石膏湿法脱硫装置进行经超低排放改造后,脱硫性能仍未达标。后经再次改造,提升了吸收塔的二氧化硫脱除能力和硫负荷适应能力,实现了二氧化硫总量和运行能耗的降低,给电厂带来了环境和经济上的效益。
After ultra-low emission transformation,the limestone gypsum wet desulfurization device of a 600 MW coal-fired unit failed to meet the desulfurization performance standard.After the reconstruction,the sulfur dioxide removal capacity and sulfur load adaptability of the absorption tower were improved,and the total sulfur dioxide and operation energy consumption were reduced,which brought environmental and economic benefits to the power plant.
