广东省燃煤机组超低排放改造成本收益分析

收集了300 MW及以上燃煤机组进行超低排放改造的12项典型技术组合,对各项技术组合的建设成本、运行费用、年收益进行核算,计算出各项技术的单位改造成本和收益,并绘制出广东省300 MW及以上燃煤机组进行超低排放改造的成本-收益曲线。结果显示：当累计发电量为2 333亿kW·h,广东地区燃煤机组改造总成本与总收益相平衡,纳入统计的机组包括：执行特别限值地区的所有300 MW及以上燃煤机组以及执行一般限值地区的7台1 000 MW及以上新建机组进行超低排放改造。

Cost Benefit Analysis on Coal-Fired Unit Modification with Ultra-Low Emission in Guangdong

In this paper, the investment cost, running expenses and annual benefit of 12 typical ultra-low emission technical combinations are examined based on the data collected from the 300-MW and above coal-fired power generation units in Guangdong Province. The unit cost and benefit of each combination are calculated and the cost-benefit curve is produced. The results show that the total control cost and benefit are balanced when the cumulative generation volume reaches 233.3 billion kW·h. To realize the balance, the ultra-low emission modification should be implemented by all the 300-MW and above coal-fired units in the key regions and seven 1 000-MW and above units in the general regions.
