伴随我国能源结构调整政策的实施，燃煤火电机组节能减排技术得到了极大的发展，近年来国内出现了一批现役燃煤火电机组提升参数改造的典型案例。本文对提升参数改造技术的发展历程、技术特点和典型案例进行了综述。在此基础上，针对提升参数改造技术在节能潜力、机组增容、受热面调整方式、投资收益比和未来发展等方面进行了分析。提升参数改造若与现役机组延寿改造同步实施，将会提高该技术的经济性，同时也会提升改造后机组的生存几率。

Energy saving and emission reduction technology of coalfired thermal power units has been greatly developed along with the implementation of China′s energy structure adjustment policy. In recent years,a number of typical cases of parameters increasing reformation have been conducted for active coalfired thermal power units. In this paper,the development process,technical characteristics and typical cases of parameters increasing reformation technology are reviewed and analyzed. On this basis,aiming at the parameters increasing reformation technology,the analyses are focused on the energy saving potential,unit power output capacity increase,heating surface adjustment mode,investment income rate and trend of development. If parameters increasing reformation and lifeextension reformation can be conducted synchronously,the technical economy and the power units competitiveness can be both improved.
