摘要
在某 30 0MW机组燃煤锅炉电除尘器上对PAHs排放进行了试验研究 ,分析比较了不同煤种燃烧后电除尘器前后PAHs的浓度变化。为了定量评价不同PAHs排放对环境的危害 ,引入了毒性当量的概念。试验结果表明 ,电除尘器对PAHs脱除效果并不理想 ,且受工况影响较大。
Test and study on polycyclic aromatic hydrocarbons (PAHs) emissions have been carried out on electric precipitators (EP) in a 300MW coalfired power plant, the variation of PAHs concentration before and after the EP under combustion conditions of different coal sorts being analysed and compared. In order to quantitatively evaluate influence of different PAHs emissions upon the harmfulness to environment, the concept of toxicity equivalence has been introduced into this paper. The test results show that the affect of EP on PAHs removal is not very good, and being greatly influenced by operation conditions of the EP.
