660MW机组基建过程中对脱硫装置的改进

国家环保部对脱硫装置取消旁路烟道提出明确的要求,2011版《火电厂大气污染物排放标准》对SO2排放提出了更高的标准。某电厂660 MW机组在建设过程中,积极采取措施,对相关系统进行配套优化,提高机组的可靠性和脱硫装置的性能保证值,避免机组投产后的后期改造,节约了投资成本,并保证了脱硫设施满足环保执行标准提高的需要。

Improvement of Desulphurization System of 660 MW Power Unit During Construction Process

The State Environment Protection Department has made clear requirement for removing the bypass flue in the desulfurization systems. The 2011 version of Emission Standard of Air Pollutants for Thermal Power plants has also imposed higher demand on the sulfur dioxide emissions. In the construction process of one 600 MW power unit, active measures were adopted to optimize the related systems and improve the reliability of generation units. This can ensure that no more large reform is needed in future. The investment cost is reduced, the adopted desulphurization system, however, can meet higher demand.
