Abstract
Integrated gasification combined cycle (IGCC) is an efficient, low-pollution clean coal power generation technology and efficient use of IGCC technology is helpful to realize clean conversion and comprehensive utilization of coal resources in China. This paper analyzed the factors that influence the power supply efficiency of IGCC power plants, determined assessment model for power supply efficiency of IGCC power plants. Then based on IGCC power plant construction specific data including power supply efficiency, combining the general technical and economic evaluation of the project, the technical and economic evaluation step of IGCC plant was determined. The economic evaluation of IGCC power plant was carried out as well as sensitivity analysis in terms of static total investment, utilization hours and standard coal tax price. The results showed that introduced IGCC of 40 megawatt had higher tariff and utilization hours had maximum impact on tariff.
