生活廢棄物 處理方法에 따른 運營效率 比較 分析

The comparative analysis of operation efficiency by treatment process of municipal waste

For incinerating life wastes, Goyang-City set up and operated Stoker-type incinerating treatme nt facility from 1995.12.1 to 2009.12.14, and then Goyang-city set up and operated pyrolysis/gasification․melting type incinerating treatment facility which is the only work place in the country installing and running the incinerating treatment from 2006.05.12 to 2010.04.01 So the analysis results for operation factors to life wastes by incinerating treatment method(Stoker, pyrolysis/gasification·melting) showed that the average treatment volume for life wastes was very high by 137% in a pyrolysis/gasification·melting treatment compared to Stoker type(comparison based on lower calorific value of 2,900Kcal/kg), and the generation volume of fly ash by pyrolysis/gasification․melting treatment which is 4.69% compared to incineration volume was a bit more as the generation volume of fly ash by Stoker type which is 4.0% compared to incineration volume. And, supplying in Korea District Heating Corporation were a bit high as those by Stoker type was 392Gca/day, and that by pyrolysis/gasification·melting treatment was 383Gcal /day, and the treatment efficiency of nitrogen oxide(NOx) by pyrolysis/gasification·melting treatment was 85.6%. and the treatment efficiency of nitrogen oxide(NOx) by Stoker type was 73.9%. It showed that the treatment efficiency of nitrogen oxide(NOx) by pyrolysis/gasification·melting treatment was more efficient than the treatment efficiency of nitrogen oxide(NOx) by Stoker type about 11.7%. It indicated a good treatment efficiency going beyond the theoretical treatment efficiency(70%) of Nitrogen Oxide in SNCR System as one of treatment methods for nitrogen oxide of atmospheric pollutants exhausted from incineration treatment facilities. The comparison of exhaust concentrations of hydrogen chloride(HCl) and sulfur oxide(SOx) showed that HCl concentration by pyrolysis/gasification·melting treatment emitted 1.9ppm(average) in 150tons/day × two units, and sulfur oxides (SOx) concentration by pyrolysis/gasification·melting treatment emitted 0.8ppm, and HCl concentration by Stoker type incinerating facility was 1.3ppm in 300tons/day, and sulfur oxides(SOx) concentration by Stoker type emitted 0.6ppm, which indicated that the exhaust concentration of HCl and sulfur oxides(SOx) by incineration method was not so much different.
