One of the concepts of energy recovery, waste energy has attracted attention as a technology that contributes considerably to the replacement of fossil fuels which are becoming depleted and to the dissemination of renewable energy for Intended Nationally Determined Contributions (INDC). In this study, the long-term operation data of domestic municipal solids waste (MSW) incineration facilities were evaluated for the steam power generation efficiency when applying the elemental technologies. In addition, the energy savings and GHG reductions were calculated by the power generation efficiency increment. In terms of enhancing the capability of waste heat recovery, the power generation efficiency was examined based on the assumption that the low calorific power of 2,000~3,000 kcal/kg, 5,000~7,000 ㎥/ton exhaust gas, boiler outlet temperature of 190~300℃ and the combustion air ratio of 1.0~2.0. When applying elemental technologies to the incineration procedure, the power generation efficiencies were 0.74~0.85%. Energy savings per ton of MSW were estimated to be 79.2 MWh/ton in low temperature economizer (LTE) and 68.8 MWh/ton in low air ratio combustion (LARC). The estimated GHG reductions were 206,072 ton-CO₂/yr in LTE and 178,892 ton-CO₂/yr in LARC. This is expected to reduce operation costs by 4,328 million and 3,757 million KRW by conversion to economic benefits.
