燃煤电厂烟气提水方案的优化研究

Optimization Research on Flue Gas Water Extraction Scheme for Coal-fired Power Plant

烟气取水方案主要为脱硫塔内提水与脱硫塔外提水两种,为了能较为清晰地反映不同取水方案对燃煤电厂技术经济性的影响,现将脱硫吸收塔内提水及脱硫塔外提水按照相同边界条件进行技术经济比较。通过技术方案对比与现场调研可以得出,脱硫塔内提水方案现场实际应用情况较好,提水量能满足设计提水量,且初投资较低,具有较好的技术经济性。

In order to clearly reflect the influence of different water intake schemes on the technical and economic performance of coal-fired power plants,the technical and economic comparison between the water intake in the desulfurization absorption tower and the water intake outside the desulfurization tower is carried out according to the same boundary conditions.Through the comparison of technical schemes and field investigation,it can be concluded that:The actual application of the water extraction scheme in the desulfurization tower is good,the water extraction can meet the design water extraction,and the initial investment is low,and has a good technical economy.
