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 NO_x and SO₂ reducing. The maximum concentrations of NO_x and SO₂ were 77 ppm and 98 ppm in exhaust gas from afterburning chamber, respectively.
