燃煤电厂在线监测系统颗粒物浓度排放系数影响因素的探讨

摘要

Seven coal-fired power plants without GGH in Shanghai were selected as the research objects. The change of particle matter emission concentration coefficient K of CEMS was studied and the impact of coal, dust remover,simultaneous removal effect of desulfurization and load conditions on the value of coefficient K was discussed in this paper.The paper found that the above-mentioned factors impact the coefficient K by changing the import concentration of particulate matter.When the import concentration of PM is low and the fluctuation range is small,the coefficient K also maintains a relatively stable state.While the import concentration of PM is high and the fluctuation range is large,the coefficient K will make a major change.%选取上海市7家未安装气-气换热器的国控燃煤电厂作为研究对象，从煤质、除尘器、脱硫协同脱除作用以及锅炉工况负荷等方面探讨对颗粒物浓度排放系数 K值产生的影响，得出上述因素通过改变脱硫进口颗粒物浓度值影响 K值，当脱硫进口颗粒物浓度较低、波动范围较小时，其 K值也维持相对稳定的状态；当脱硫进口颗粒物浓度较高、波动范围较大时，其 K值也会发生较大的变化等结论。
