Recently, many countries have been interested in waste-to-energy policy and technology due to the economic crisis from high oil price and the demands on securing the sustainable energy sources. As one of the efforts to achieve the sustainable society and maintain low impact of global warming in Korea, the act on the promotion of saving and recycling resources was enacted to implemetnt the effective reduction of waste at source level, reduce, recycling and recovery of waste to energy. Attaining an efficient recovery of waste heat in a cogeneration plant from incineration facilities is important as a resource recovery of waste to energy. In this study, the waste heat recoveries changed by reducing feed pressure in incineration conditions were analyzed. As results, changing the operating condition in steam header resulted in stable heat supply and increase of waste heat recovery.
