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.
