생활폐기물 소각시설의 운영 실태 분석을 통한 에너지회수 효율 개선방안 검토 = A Study on Improvement Measures of Energy Recovery Efficiency through Analysis of Operational Status of Municipal Solid Waste Incineration Facilities

다국어 초록 (Multilingual Abstract)

This study was carried out to examine the improvement plan by analyzing the characteristics of imported wastes,operation rate, and benefits of energy recovery for incineration facilities with a treatment capacity greater than 50 ton/day. The incineration facility capacity increased by 3,280 tons over 15 years, and the actual incineration rate increasedto 2,783 ton/day. The operation rate dropped to 76% in 2010 and then rose again to 81% in 2016. The actual calorificvalue compared to the design calorific value increased by 33.8% from 94.6% in 2002 to 128.4% in 2016. The recoveryefficiency decreased by 29% over 16 years from 110.7% to 81.7% in 2002. Recovery and sales of thermal energy fromthe incinerator (capacity 200 ton/day) dominated the operation cost, and operating income was generated by energy sales(such as power generation and steam). The treatment capacity increased by 11% to 18% after the recalculation of theincineration capacity and has remained consistently above 90% in most facilities to date. In order to solve the problemof high calorific value waste, wastewater, leachate, and clean water should be mixed and incinerated, and heat recoveryshould be performed through a water-cooled grate and water cooling wall installation. Twenty-five of the 38 incinerationfacilities (about 70%) are due for a major repair. After the main repair of the facility, the operation rate is expected toincrease and the operating cost is expected to decline due to energy recovery. Inspection and repair should be carriedout in a timely manner to increase incineration and heat energy recovery efficiencies.
