摘　　要：煤炭地下气化与燃气—蒸汽联合循环发电技术具有节约资源和改善环境的优点。在华亭试验的基础上,计算了地下气化联合循环发电在作为自备电厂时的经济参数并进行了敏感性分析。其内部收益率为16.8%、净现值为3 948.16万元、动态投资回收期为8.93 a,在经济上是完全可行的。敏感性分析得出销售电价对项目的影响较大。在目前情况下,在我国东部地区有较好的商业化前景。从长期看来,地下气化要加快发展,也需要国家出台相关政策支持。Underground coal gasification and gas-steam combined cycle power generation technology has the advantages of saving resources and improving environment.At the basis of Huating trial,we calculate the economical parameters and analyze sensitivity when Underground coal gasification combined with power generation with gas-evapour combined cycle as captive power plant.Its internal rate of return is 16.8%,the NPV is 3 948.16 yuan,and the dynamic investment recovery period is 8.93 years.It’s economically feasible.Sensitivity analysis results greater impact on the project’s sales price.In the present case,it has good commercial prospects in eastern.From a long-term view,to accelerate the development of underground coal gasification,we need the introduction of relevant national policies to support.
