초록
Industrial waste heat available from ceramic plants is investigated to understand economic benefits gained from the heatintegration of waste heat with the district heating systems. One of the scenarios for the case study is to consider the combineduse of waste heat for generating electricity via the ORC (Organic Rankine Cycle), as well as for supplying heat as a heatingsource to the district heating systems, while the other is to maximize the utilization of waste heat as heating only. A processsimulation framework using AspenHYSYS® is built to estimate the amount of waste heat available from the kiln exhaust gas. The integration of ORC and district heating systems is also modeled by an established framework. Two profiles forcharacterizing changes in heating demand are considered on a daily basis and annual basis, while three levels of insulationefficiency for the heat storage facility are considered. Case study clearly illustrates that heat recovery with only using districtheating systems can provide more benefits than using ORC about 64~86% of cost savings. Technical issues related to overthe-fence heat recovery in practice are discussed.
