城市生活垃圾_MSW_与煤混烧过程中气体污染物的排放

人者在0．2MW循环流化床上进行了城市生活垃圾与煤混烧实验。在线测量了NOx,NO,N2O,SO4,HCl和Cl2排放浓度，探讨了城市生活垃圾与煤掺煤比（R）和温度对气体污染物排放的影响。实验结果显示，在混烧过程中，随拉圾加入量的增加，NOx,NO,N2O和SO4排放量减少，Cl2排放浓度啬 。当掺烧比R不变，温度增加时，NOx，NO排放量增加，N2O排放减少，SO2，HCl和Cl2排放浓度基本不变，飞灰和底渣中二恶英含量减少。

Gaseous Pollutants Emissions during the Process of Mixed Burning of Municipal Solid Waste (MSW) and Coal

Tests involving the mixed burning of municipal solid waste and coal were conducted on a 0.2 MW circulating fluidized bed. During the tests an on line measurement of the emissions concentration of NO x , NO, N 2O, SO 2, HCl and Cl 2 was performed. An exploratory study was undertaken of the effect of municipal solid waste and coal mixed burning ratio (R) and temperature on gaseous pollutant emissions. The test results indicate that during the mixed burning process NO x , NO, N 2O and SO 2 emissions will decrease and Cl 2 emission concentration increase in case the municipal solid waste feeding amount was increased. With the mixed burning ratio R being kept constant and the temperature increased there will be an increase in the NO x and NO emissions. Meanwhile, there will also be a decrease in N 2O emissions while the emission concentration of SO 2, HCl and Cl 2 remains basically unchanged and the dioxin content in fly ash and bottom slag will decrease.
