Incineration allows for the recovery of energy from combustible waste. It would be highly beneficial to society if this heat could be used efficiently. However, due to the difficulties involved with storing and transporting heat energy, consumers would need to live near incineration facilities in order to make efficient use of this heat energy. Moreover, it is usually difficult to achieve a balance between heat demand and supply. For instance, although there is a significant demand for heat in Northern Europe, the demand for electricity in that region is larger than the demand for heat in Central/Southern Europe. Hence, the preferred form of energy recovery differs depending on the nation or regional conditions. However, there are no limitations with regard to electricity because it can be used in a variety of ways. As a result, leading countries such as those in the European Union and the United States have been developing technologies and building facilities to recover electricity. In Korea, stable operation (steam condition 200-300℃, 20-25bar) was given priority over energy recovery because the country’s background with regard to the measure for dioxin is different from that of Europe or the United States. In addition, the produced energy has been mostly self-consumed rather than sold. While Korea is implementing incineration energy recovery, the country’s incineration power generation is considerably lower than that of leading nations. According to the 6thbasic plan for power supply(2013–2027), which was announced in 2013, the government of Korea is planning to secure a power generation capacity of 688 MW (as of 2012, a level of 74 MW was attained) from waste. Accordingly, this paper examined trends and efficiency improvements for incineration power generation in leading countries.
