초록
포항철강산업단지에서 발생하는 폐열을 회수하기 위하여 주요 기업의 폐에너지 발생 규모에 대한 데이터베이스를 설문조사를 통해 구축하고, 가시적인 기법을 적용하여 에너지 교환망 구축방안을 고려하였다. 폐열의 온도 수준, 유효에너지 발생량, 폐에너지 발생 기업과 예상 수요 기업의 거리, 구축비용 등의 관점에서 잠재성이 높은 에너지 교환망을 제시하고 경제성을 평가하였다. 최종 제안된 4개 기업의 에너지 교환망의 투자비 회수기간은 평균 2.8년이고, 에너지 절감량은 연간 4,778TOE로 분석되었다. 현재 사용되는 LNG를 폐열 회수로 대체하면 연간 약 11,160 CO2 ton을 감축할 수 있다.
A detailed database of waste heat is built to propose energy exchange networks to recover waste energy in Pohang Steel Industrial Complex. A visualized technique is used to figure out the status of waste heat energy and to suggest potential energy exchange networks. Several energy networks are proposed in terms of temperature level, the amount of available energy, distance, and construction cost. A simple economical assessment is applied to the energy exchange networks which have higher economic potential. Their average payback period is estimated to be 2.8 years. The total amount of energy saving by constructing the proposed energy exchange networks is 4,778 TOE per year. It corresponds to 11,160 ton CO2 reduction with the assumption that the recycled waste energy replaces the use of LNG in energy-demanding companies.
