New MSWI system have been developed. The combustion using oxygen enriched air (OEA) and flue gas recirculated (FGR) from outlet of bag filter are applied in this system. The influences of that combustion on solid combustion, repression of dioxin emission and any more were studied experimentally using bench-scale facility. In the test of the combustion using OEA it was revealed that the ignition loss of bottom ash, dioxin emission and CO emission decreased as oxygen concentration in OEA increase. However, NOx emission increased by oxygen concentration being high. To decrease NOx emission, the test of combustion using OEA and FGR was done. It was found out that NOx emission was repressed till same level as combustion using normal air and 80% dioxin emission decreased by comparison with the dioxin emission in the test of combustion using OEA.
