摘要
为了解常规燃煤机组碳捕集系统的技术经济性,以基准情景为基础,根据国内某10万t CO_2燃烧后捕集系统的投资情况,利用生产能力指数法对5种脱碳情景的投资进行估算。在保证内部收益率为8%的前提下,分析了5种脱碳情景的上网电价、CO_2综合减排成本及其敏感性。结果表明,CO_2综合减排成本中,厂内碳捕集成本比例最大;随着燃料价格的上涨,CO_2综合减排成本逐渐增加;随着CO_2综合收益的增加,上网电价可以逐渐下降。
In order to investigate technology and economy of carbon capture system of conventional coal-fired unit,based on the standard situation and the investment of one 105 tons of post-combustion CO2 capture system in domestic, the investments of five kinds of decarburization situation were estimated by production capacity index method. On the premise of 8% internal rate of return, the electricity prices, CO2 comprehensive cost and sensitivity of five kinds of decarburization situation were analyzed . The results showed that carbon cap- ture cost in the plant was the largest part in the total CO2 emission reduction cost. With the fuel prices rising, CO2 emission reduction cost gradually increased. With CO： comprehensive income increasing,feed-in tariff gradually declined.
