Abstract

국내 무연탄을 사용하는 미분탄 화력보일러(영동화력 2호기)를 대상으로 비교적 고효율, 저비용으로 전기를 생산하는 청정보일러인 순환유동층 보일러로의 전환 시 경제성 평가 및 민감도 분석을 수행하였다. 경제성 평가는 크게 순환유동층 보일러로의 전환 시와 기존의 미분탄 보일러를 유지 시에 각각의 투자금액에 대한 경제성 평가와 이의 비교를 수행하였으며, 더불어 전력시장의 상황 변화에 따른 경제성 민감도 분석을 수행하였다. 경제성 평가 결과, 현 상태에서는 전력산업기반기금이 지원을 받고 있는 무연탄 발전사업의 특성상 기존 보일러를 유지하는 것이 경제성 지표가 더 좋은 것으로 평가되었으나, 전력산업기반기금의 지원 형태 및 그 규모에 따라 순환유동층으로의 전환이 장기적 발전사업 및 기반기금의 효율적 집행 그리고 국가 에너지 이용률에 있어 더 좋은 경제 지표를 나타내는 것으로 평가되었다.

The economical efficiency of conversion of the PC (pulverized coal) firing boiler to the CFB (circulating fluidized bed) boiler which used Koran anthracite as fuel was evaluated. The economic feasibility study was also carried out with regard to maintenance of the existing PC boiler. The sensitivity of economical efficiency with variation of the electric power and coal industry and the policy of government was analyzed and compared. As a results of the evaluation, the economical efficiency of maintenance of the existing PC boiler was higher than that of conversion to the CFB boiler because of the special policy of the government for Korean anthracite. However, the conversion to the CFB boiler was more economically attractive from a point of view of effective use of energy resources and future electric power industry. Additionally, the fund support for electric power industry using Korean anthracite would be effective as changing the policy of the government.
