Abstract

순환유동층 연소로에서 폐목질계 바이오매스를 이용한 5 MWe 규모의 발전시설에 대한 경제적 타당성에 대하여 고찰하였다. 초기투자비, 폐목재의 가격, 탄소배출권, 계통한계가격과 같은 주요 변수들이 사업의 경제성에 미치는 영향을 분석하였다. 폐목재를 무상으로 공급하고, 기반투자비용 106.5억원, 계통한계가격 99원/kWh의 기준에서 사업의 내부수익률은 16.67%로 계산되어 사업성이 비교적 높은 것으로 예상되었다. 사업의 수익에 영향을 크게 미치는 인자는 계통한계가격, 가동율, 초기투자비, 폐목가격, 탄소배출권의 순으로 나타났다. 또한 사업 위험도를 관리하기 위하여 판매처를 다양화할 수 있는 방안의 하나로 열판매가 가능한 열병합발전을 고려할 필요가 있는 것으로 판단된다.

Economic feasibility of power generation system using waste woody biomass in a circulating fluidized bed combustor has been investigated. Effects of important variables such as capital investment, cost of waste wood, certified emission reduction(CER), system marginal price(SMP) on the benefit of business have been analyzed. Internal rate of return(IRR) was predicted as 16.67%, which implicates the business is promising based on the assumptions such as SMP_x000D_ of 99Won/kWh, capital cost of 10.65 billion won, and complimentary providing of waste wood. Major factors affecting the benefit of business were as follows; system marginal price, operational rate, capital investment, expenditure of waste wood, certified emission reduction. In addition, it must be necessary to consider CHP power plant providing steam as one of the means to diversify sales network, for the management of the business risk.
