燃气轮机脱硝技术现状及发展策略研究

Present Situation and Development Strategy of Denitration Technology for Gas Turbine

在目前的发电机组烟气的脱硝技术中最为常用的就是SCR技术,但是针对燃气轮机来说,此技术应用中催化剂的研究则比较少。本文针对燃气轮机运行中燃气所表现出的与燃煤机组的不同,结合目前国内外燃气轮机的脱硝现状以及燃机系统的脱硝技术和特点,分析燃气轮机SCR脱硝催化剂的性能以及未来的发展趋势。

SCR technology is the most commonly used in the fl ue gas denitrifi cation technology of generator set at present,but for gas turbine,the research on catalyst in the application of this technology is relatively small.Therefore,in view of the difference between gas turbine and coal-fi red unit in operation,it is necessary to analyze the performance and future development trend of SCR denitration catalyst for gas turbine based on the current denitration status of gas turbine at home and abroad and denitration technology and characteristics of gas turbine system.
