【 摘 要 】

The operation mode of slurry recirculation pump and the limestone slurry feed were optimized in order to reduce the power consumption and material consumption of the wet flue gas desulfurization facility in a 330MW ultra low emission coal-fired power unit. The results show that the electricity consumption of WFGD has decreased by optimizing the operation mode of the slurry recirculating pumps. The operating current of the slurry recirculation pumps decreased by 33.25A on average and the electricity charge could be saved 441,000 yuan per year. A feed-forward PID control strategy of limestone slurry feed has been successfully used in the WFGD. A desired tracking performance is achieved and the limestone slurry supply was reduced by 0.0187 ton/(ten thousand of kWh).
