摘要
因煤质变化,锅炉烟气SO_2浓度超过石灰石-石膏湿法脱硫装置设计值,严重影响脱硫系统的正常稳定运行,导致烟气出口SO_2含量频繁超标。介绍了石灰石粉、脱硫浆液、石膏中各化学工艺参数对石灰石-石膏湿法脱硫装置运行的影响,并根据电厂实际情况提出相应的优化指标,改善运行工况。
Due to coal quality decline, the SO_2 in boiler fume exceeded the designed value of the limestone-gypsum wet desulfurization system, which seriously affected the normal stable operation of the desulfurization system and caused frequent SO_2 out-of-limits.The effect of chemical process parameters of limestone powder, desulfurization sludge and gypsum on the operation of the limestone-gypsum wet desulfurization system is introduced.Corresponding optimization index is also put forward according to the actual situation of the power plant to improve operation condition.
