One of the concepts of energy recovery, waste energy has attracted attention as a technology that contributesconsiderably to the replacement of fossil fuels which are becoming depleted and to the dissemination of renewable energy forIntended Nationally Determined Contributions (INDC). In this study, the long-term operation data of domestic municipal solidswaste (MSW) incineration facilities were evaluated for the steam power generation efficiency when applying the elementaltechnologies. In addition, the energy savings and GHG reductions were calculated by the power generation efficiency increment. Interms of enhancing the capability of waste heat recovery, the power generation efficiency was examined based on the assumptionthat the low calorific power of 2,000~3,000 kcal/kg, 5,000~7,000 m3/ton exhaust gas, boiler outlet temperature of 190~300℃ andthe combustion air ratio of 1.0~2.0. When applying elemental technologies to the incineration procedure, the power generationefficiencies 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 LTEand 178,892 ton-CO2/yr in LARC. This is expected to reduce operation costs by 4,328 million and 3,757 million KRW byconversion to economic benefits.
Abstract
One of the concepts of energy recovery, waste energy has attracted attention as a technology that contributesconsiderably to the replacement of fossil fuels which are becoming depleted and to the dissemination of renewable energy forIntended Nationally Determined Contributions (INDC).

In addition, the energy savings and GHG reductions were calculated by the power generation efficiency increment.
