Abstract :
A laboratory scale updraft fixed bed gasifier was designed to study the characteristics of gasification and incineration of organic solid wastes. Research had been carried out on the emission characteristics of SO2, NO and NO2 of solid wastes in the gasifier in different operation condition, the effects of reactor temperatures (650degC-790degC), gasification mediums (air and oxygen) and the flow rate of gas mediums (1 m3/h, 3 m3/h and 6 m3/h) on the emission of SO2, NO and NO2 were studied. The results showed that lower reactor temperature and flow rates of gas medium were in favor of the yield of NOx and SO2 reducing. The maximum concentrations of NOx and SO2 were 77 ppm and 98 ppm in exhaust gas from afterburning chamber, respectively.
