摘    要:针对大型燃煤循环流化床锅炉,研究锅炉负荷和钙硫比对烟气中及电除器飞灰中多环芳烃含量和种类的影响,试验结果表明:随着锅炉负荷和钙硫比升高,烟气中和飞灰中多环芳烃的种类和含量减少,但负荷和钙硫比对烟气中和飞灰中多环芳烃的影响效果是不同的。

关 键 词:锅炉负荷  钙硫化  多环工  燃煤流化床锅炉  PAHs排放  试验  烟气除尘  飞灰

Abstract:The influence of boiler load and Ca/S ratio on the distribution of polycyclic aromatic hydrocarbons (PAHs) in ESP (Electric Static Precipitator) ash and flue gas was studied on a commercial operated 220T/H CFBB (Circulated Fluidized Bed Boiler). The results demonstrated that the boiler load and Ca/S ratio have different influences on the categories and concentrations of PAHs in ESP ash and flue gas.
Keywords:boiler load  Ca/S ratio  PAHs
