Abstract
We installed water cooled grate bars in a domestic MSW plant, and we confirm steady operation. No wear of the grate bars was observed after one year operation. We also applied exhaust gas re-circulation (EGR) system to domestic MSW plant. As a result, the following merits were confirmed compared with the case that EGR system is not used. -the air ratio was reduced to 1.3. -CO concentration at stack inlet has been reduced by 25% -NOx concentration at DeNOx tower inlet has been reduced by 31% -Flue gas quantity has been reduced by 9%
