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 SO(2), NO and NO(2) of solid wastes in the gasifier in different operation condition, the effects of reactor temperatures (650 degrees C-790 degrees C), gasification mediums (air and oxygen) and the flow rate of gas mediums (1m(3)/h, 3m(3)/h and 6m(3)/h) on the emission of SO(2), NO and NO(2) were studied. The results showed that lower reactor temperature and flow rates of gas medium were in favor of the yield of NO(x) and SO(2) reducing. The maximum concentrations of NO(x) and SO(2) were 77ppm and 98ppm in exhaust gas from afterburning chamber, respectively.
